Description: ELECTROMAGNETICALLY POWERED HYDRAULIC ENGINE APPARATUS AND METHOD TECHNICAL FIELD: This invention relates to engine apparatus and 5 methods for producing work at an output thereof. More particularly, the present invention relates to electrically powered engine apparatus and method of producing work at an output thereof. Even more particularly, the present invention relates to 10 electromagnetical ly powered apparatus that produce work at an output thereof by means of combining electromagnet devices and hydraulic devices to produce work useful in propulsion of vehicles and other power input dependent apparatus. 15 BACKGROUND ART: The principles of work are considered well known to the artisan as they relate to rectilinear and rotary motion of an object, suffice it to say that it concerns the transference of energy produced by the motion of an 20 object by application of a force and is measured by the product of the force and displacement of the object. The internal combustion engine is a known apparatus employed to perform work by cranking a crankshaft. The advantage to mankind in having the internal combustion 25 engine, is without question, superior to other tools developed by man to manage the daily tasks of living, including the electric motor whose rotor equates to the crankshaft in performing work. The internal combustion engine has had much research attention and has been 30 perfected to yield great satisfaction in work efficiency, torque and speed. But, while the advantages are recognized by all, the polluting disadvantages to the environment have been largely ignored to the detriment of society. Electric motors ιi- 35 have replaced many machine application formerly relying on the internal combustion engines, and while they have also enjoyed much technological advances, they have not been perfected to the point of replacing the greatest source of pollution, namely the automobile engine, (see Wall Street Journal Article entitled: "GM Says It Plans an Electric Car, but Details Are Spotty", page Bl , dated Thursday April 19, 1990) . The internal combustion engine requires timely firing of a spark within a cylinder chamber having gone through a compression stroke to produce the power stroke that moves a piston/rod in a re iproca ing manner to drive a crankshaft having a power output attachment. The end-use apparatus of the power output attachment are many, and include the automobile which has required many engine variations and cylinder block configurations to harness the energy produced at the crankshaft that results into propulsion of the automobile. The electric motors traditionally require large battery units to continually produce rotating drive train power, and as alluded to in the Wall Street article, have yet to be commercially attractive as an alternative engine technology. Therefore, a need is seen to exist for an engine apparatus that maintains the attributes of an internal combustion engine, including high performance parameters such as horsepower ratings, speed and torque packaged in a small volume and that further includes the non-polluting attributes of an electric motor without the need for large storage battery units. DISCLOSURE OF INVENTION: Accordingly, the primary object of the present invention is to provide an engine apparatus having high performance parameters, such as horsepower ratings, speed and torque without the disadvantages of an internal combustion engine, primarily pollution associated with the combustion of petroleum products. Another object of the present invention is to provide an engine that operates clean similar to the electric motor but that is more efficient in the conversion of electrical energy to mechanical energy and that also utilizes petroleum products in a non- combustible manner. A related object of the present invention is to provide a vehicular apparatus that utilizes an engine having the foregoing objects. In the most basic embodiment, the present invention satisfies the foregoing objects by providing an engine apparatus that utilizes electrical energy to activate an opposing arrangement of electromagnets that controllably produce magnetic fields acting on a piston having an embedded permanent magnet to produce repeated compression strokes that act on a fluid within a cylinder to drive a hydraulic motor shaft. The electromagnet arrangement includes a dual-wire wound coil arrangement such that the piston with the permanent magnet is repeatedly repelled within the cylinder during alternating pulsed 0N-0FF STATES of energization on each of the wire windings of the electromagnets to produce alternating polarities to effect delivery of pressurized fluid to the hydraulic motor. The repulsion force acting at one end of the piston is complemented by the attraction force acting at the opposite end of the piston, which repulsion and attraction forces are reversed at each end upon the occurrence of a change in polarity of the electromagnets. Under controlled electrical, closed-loop primed hydraulic conditions, and during any given cycle of operation, consisting of a compression stroke and a return stroke of the piston, an input fluid is introduced at an input port corresponding to the chamber-end of the cylinder associated with the piston in a return stroke, concurrently an output fluid is delivered from an output port corresponding to the compression chamber-end of the cylinder associated with the piston in a compression stroke. The output fluid is delivered to and maintained at a high pressure by a pressure stabilizer to either, drive a hydraulic motor, or to be directed to a bypass valve for an idle state of operation, both the hydraulic motor and bypass valve being hydraul ical ly coupled back to the input ports of the cylinder via a fluid reservoir. In a vehicular application, the hydraulic motor's drive shaft is coupled to the drive train of a vehicle to produce propulsion. The underlying principles of the electromagnetical ly driven hydraulic pump facilitate the design of other engine configurations having at least one set of dual piston-permanent magnet means within a respective cylinder, each set of dual piston- permanent magnet means being interconnected by a common shaft to synchronize delivery of the pressurized fluid output to the hydraulic motor and being responsive to alternating polarity states on oppositely disposed electromagnets. The interconnecting common shaft region may be modified to increase operating pressure of the hydraulic engine by placement of a third electromagnet centrally in a given cylinder bank to complement the compression and return strokes produced by the end electromagnets. Therefore, to the accomplishments of the foregoing objects, the invention consists of the foregoing features hereinafter fully described and particularly pointed out in the claims, the accompanying drawings and the following disclosure describing in detail the invention, such drawings and disclosure illustrating but three embodiment of the various ways in which the invention may be practiced.

BEST MODE OF CARRYING OUT THE INVENTION: Figs. 1 and 2 illustrate a basic embodiment 10 comprising a block arrangement 11, first and second electromagnetic means EMI and EM2 disposed at opposite ends of block 11, and check—valved fluid input ports CV1 , CV3 for controlling input fluid flow FI, F3 and output port CV2, CV for controlling fluid output flow F2, F . Electromagnetic means EMI, EM2 each comprising a stationary, centrally disposed core member CRl, CR2, dual-winding coil members Wl , W2 and mechanical interface ends Bl , B2. As best seen in Fig. 2, basic embodiment 10 also comprises a single piston-permanent magnet means 50 disposed in a cylindrical chamber 51 of block 11, which block 11 is provided with ports 52, 53, 5<^ and 55 for the attachment of check valves CV1-CV - which control the flow of fluid Fn, initially delivered into cylinder chamber 51 during a return stroke, as indicated by fluid flow arrows FI , F3, and which is expelled during a compression stroke, as indicated by fluid flow arrows FI, F3. Piston-permanent magnet means 50 is designed having rings RI , R , for maintaining compression, and an embedded permanent magnet 56 which by example, is shown polarized south S and north N, and which is understood to be an arbitrary arrangement of the embedded permanent magnet. Any arrangement of the permanent magnet 56 is suitable so long as the polarity of the end electromagnets is synchronized to complement a repelling state at one end of the embedded permanent magnet with ar. attraction state at the other end of the permanent magnet. Thus, as illustrated in Fig. 2 and assuming that piston 51 is to move in the direction of arrow Al, then electromagnet EMI will be electrically energized to magnetically polarize core member CRl to a north (N) polarity during the time associated with arrow Al, and concurrently, electromagnet EM2 will be energized to polarize core member CR2 to a south S polarity. Also, assuming that piston 50 has reached the end of stroke Al to begin a return stroke, as indicated by motion arrow A2, then electromagnet EMI will be electrically energized to polarize core member CRl to a south S polarity during the time associated with motion arrow A2, and concurrently, electromagnet EM2 will be energized to polarize core member CR2 to a north (N) polarity. Fig. 2, shows permanent magnet 56 having protruding ends 56a, 56b, which are intended to be received within respective cavities CRa, CRb, and which are intended to increase the magnetic pull by the electromagnets, hence generation of higher fluid pressures. By design, cylinder chamber 51 is filled with fluid via either of the input ports/check valves (52/CV1) or (5 VCV3) during a return stroke, depending which end of cylinder 51 is in a return stroke state that creates a vacuum that draw fluid from fluid reservoir 600, see Fig. 3. Similarly, cylinder 51 is emptied under compression via either of the output ports/check valves (53/CV2) or <55/CV<+>, also depending upon which side of cylinder 51 is under compression. Fluid Fn may be any petroleum fluid product, such as those commonly used in automatic transmissions. Figs. <+ and 5 illustrate a second embodiment 100 comprising a block arrangement 111, first and second electromagnetic means 200 and 300 disposed at opposite ends of block 111, and check-valved fluid input ports CV1, CV3, CV5 and CV7 for controlling input fluid flow FI, F3, F5, and F7 and output ports CV2, CV , CV6, and CVB for controlling fluid output flow F2, F , F6, and F8. Electromagnetic means 200, 300 each comprising a a stationary, centrally disposed core member CRll, CR22, dual-winding coil members Wll, W22 and mechanical interface ends Bl, B . Electromagnetic means 200, 300 differ from electromagnets EMI, EM2 in their magnetic characteristics relating to attraction/repulsion capabilities for reciprocating a dual piston configuration illustrated in Fig. 5. As best seen in Fig. 5, embodiment 100 also comprises a dual piston- permanent magnet means 103, 10-+ within respective cylinder chambers 101a, 101b, interconnected by a non¬ magnetic common shaft 102 used for synchronized operation and increased fluid throughput. Block 111 is provided with ports lll(a-h) for the attachment of check valves CV1-CV8 which control the flow of fluid Fn, initially delivered into cylinder chambers 101a, 101b during a return stroke, as indicated by fluid flow arrows FI , F3, F5, and F7, and which fluid Fn is expelled during a compression stroke, as indicated by fluid output flow arrows F2, F-+, F6, and F8, Piston- permanent magnet means 103, 10^ and interconnecting common shaft 102 are designed having rings 103a, 10-+a, 102a, respectively, for maintaining compression. Piston-permanent magnet means 103, 10-H- ar≡ each provided with an embedded permanent magnet PMl, PM , which by example, are shown polarized south S and north N, respectively, at ends adjacent core members CRll, CR22, and which polarization is understood to be an arbitrary arrangement of the embedded permanent magnets. Any arrangement of the permanent magnets PMl, PM2 is suitable so long as the polarity at the inner ends of electromagnets 200, 300 is synchronized to repel one of the embedded permanent magnet and concurrently attract the other embedded permanent magnet. The non-magnetic interconnecting shaft 102 serves the mechanical function of maintaining synchronized reciprocating action of piston-permanent magnet means 103, 10-+. Thus, as illustrated in Fig. 5 and assuming that pistons 103, 10 are to move in the direction of arrow A22, then electromagnet 200 will be electrically energized to magnetically polarize core member CRll to a north N polarity at an inner end during the time associated with motion indicated by arrow A2 , and concurrently, electromagnet 300 will be energized to polarize core member CR22 to a south N polarity also at an inner end. Also, assuming that pistons 103, 104 have reached the end of a compression stroke, as indicated by motion arrow A22, then the polarity of electromagnets 200, 300 will be reversed such that electromagnet 200 will be electrically energized to polarize core member CRll to a south (S) polarity during the time associated with motion arrow All, and concurrently, electromagnet 300 will be energized to polarize core member CR22 to a north <S> polarity. Fig. 5 also shows permanent magnets PMl, PM2 having protruding ends 103b, 10<+b which are intended to be received within respective cavities CRlla, CR22a, and which are intended to increase the magnetic pull by the electromagnets, hence generation of higher fluid pressures.

Similarly, cylinders 101a, 101b are emptied under compression via either of the output ports/check valves 111 (b ,f) /CV(2,6) or 111 (d ,h)/CV<<+»8> » also depending upon which side of cylinders 101a, 101b is under compression. Fluid Fn may be any petroleum fluid product, such as those commonly used in automatic transmissions. Figs. 6 and 7 illustrate a third embodiment 3000 comprising a cylindrical arrangement 301, 302, 303 having electromagnets 700, 800 at opposing ends and a third electromagnet 900 centrally disposed within cylinder portion 302 to complement the compression and return strokes produced by end electromagnets 700, BOO. Embodiment 3000 also comprises check-valved fluid input ports CV1 and CV3 for controlling input fluid flow FI and F3 and output ports CV2 and CV4 for controlling fluid output flow F2 and F4. Fig. 7 illustrates embodiment 3000 also having a dual iston-permanent magnet means 304, 305 within respective cylinder chambers 301c, 303c and having mechanically interconnecting, non-magnetic, common shaft 901 and oppositely adjoining magnetic shafts 702, 802.

Similarly, piston-permanent magnet means 305 being magnetically coupled at one end via electromagnet 800 and at an opposite end via another end of third electromagnet 900. Central, non-magnetic common shaft 901 and oppositely adjoining magnetic shafts 702, 802 reciprocate within bores 701, 902, 801 and aid in maintaining synchronized re iprocating action of apparatus embodiment 3000 and further are aid to increase the magnetic influence of the electromagnets and hence the generation of higher fluid pressures. Electromagnetic means 700, 800 each comprising a stationary, centrally disposed core member CR , CRy (including bores 701, 801), dual-winding coil members Wa, Wb and are mechanically secured to cylinder end portions 301e, 303e via a thread arrangements Ta, Tb . Central electromagnetic means 900 comprising a stationary, centrally disposed core member CRc (including bore 902 and dual-winding coil member Wc . Central electromagnet 900 and central cylinder portion 302 being joined to inner cylinder end portions 301d, 303d via thread arrangement Tc . Electromagnetic embodiments 700, 800 differ from electromagnets (EM1,EM2), (200, 300) in their magnetic characteristics relating to attraction/repulsion capabilities for reciprocating the dual piston configuration illustrated in Fig. 7. Cylinder block portions 301, 303 are provided with ports 301 (a,b), 303(a,b) for the attachment of check valves CV(l-4) which control the flow of fluid Fn, initially delivered into cylinder chambers 301c, 303c during a return stroke, as indicated by fluid flow arrows FI and F3, and which fluid Fn is expelled during a compression stroke, as indicated by fluid output flow arrows F2 and F4. Piston-permanent magnet means 304, 305 and interconnecting shafts 702, 901, 802 are designed having rings Rb , Re, Ra, Re, and Rd , respectively, for maintaining compression. Piston-permanent magnet means 304, 305 are each provided with an embedded permanent magnet PMa, PMb, which by example, are shown polarized (north N) and (north N), respectively, at ends adjacent inner portions of core members CRx, CRy, and which polarization is understood to be an arbitrary arrangement of the embedded permanent magnets. The innermost portions of permanent magnets PMa, PMb are shown polarized (south S> and (south S), respectively, at ends adjacent opposite ends of core member CRc. Any arrangement of the permanent magnets PMa, PMb is suitable so long as the polarity of the end electromagnets 700, BOO and 900 is synchronized to repel one of the embedded permanent magnet and concurrently attract the other embedded permanent magnet. Thus, as illustrated in Fig. 7 and assuming that pistons 304, 305 are to move in the direction of arrow Aa, then electromagnet 700 will be electrically energized to magnetically polarize core member CRx to a south (S) polarity, and concurrently, electromagnet 900 will be energized to polarize one end of core member CRc to a south S polarity while the other end will be polarized to a north N polarity, and electromagnet 800 will be electrically energized to magnetically polarize core member CRy to a north N polarity, also during the time associated with arrow Aa . Also, assuming that pistons 304, 305 have reached the end of a stroke, indicated by motion arrow Aa, then the polarity of electromagnets 700, 800 and 900 will be reversed to produce motion indicated by arrow Ar of pistons 304, 305 such that ele tromagnet 700 will be electrically energized to polarize core member CRx to a north (N) polarity, and concurrently, electromagnet 900 will be energized to polarize one end of core member CRc to a north (N) polarity, while the other end will be polarized to a south (S) polarity, and electromagnet BOO will be electrically energized to magnetically polarize core member CRy to a south (S) polarity, also during the time associated with arrow Ar . Repeated and controlled changes in the polarity of electromagnets 700, BOO, and 900 will result in a reciprocating action for continuous pumping of fluid Fn in and out of chambers 301c, 303c. By design, cylinder chambers 301c, 303c are filled with fluid Fn via either of the input ports/check valves 301a/CVl or 303a/CV3 during a return stroke, depending which end of cylinders 301c, 303c is in a return stroke state that creates a vacuum that draws fluid from fluid reservoir 600, see Fig. 3. Similarly, cylinders 301c, 303c are emptied under compression via either of the output ports/check valves 301b/CV2 or 303b/CV4, also depending upon which side of cylinders 301c, 303c is under compression. Fluid Fn may be any petroleum fluid product, such as those commonly used in automatic transmissions. Fig. 5a illustrates a dc power source 400 coupled to a magnetic polarity control box 401 for changing the magnetic polarity of the electromagnets. The polarity change is facilitated by output switching means 402, 403 feeding a predetermined quantity of the electromagnets, shown generally as EM , EMn. Polarity control box 402 can be configured to electrically couple to embodiments 10, 100 or 3000, such that the appropriate dc output polarity feeds the corresponding winding lead in the dual-windings of electromagnets EMI, EM2, 200, 300, 700, 800, and 900 to generate the desired polarity, consistent with the polarity of the embedded electromagnets that are to be attracted and repelled. INDUSTRIAL APPLICABILITY: Fig. 3 illustrates a generalized vehicular application 500 comprising controlled power source 400, 401 (see Fig. 5a), electrically coupled to an electromagnetic pump 10 (100), (3000), which pump is central to a closed-loop hydraulic drive system. The close-loop system comprises an electromagnetic pump 10, (100), (3000), a fluid pressure regulator 600, a control valve 630, a bypass valve 610, a fluid reservoir 620, and a hydraulic motor 640 which includes return line 642 feeding back to fluid reservoir 620. Motor 640 is provided with an output drive shaft 641 coupled to a vehicle's drive train 700 which includes propulsion components such as transmissions and wheels (not shown). In operations power source 400, 401 provides alternating electrical energy for changing the magnetic polarities at the electromagnets EMI, EM2 (200, 300,), (700, BOO, 900) to produce reciprocating motion Al , A2, (All, A22) , (Aa, Ar ) which, assuming that the close-loop hydraulic system has been suitably primed, will cause pressurized fluid to flow in the system. The system is designed to maintain a high fluid pressure by virtue of fluid stabilizer 600 and can operate in an idle state by the use of bypass valve 610 which feeds fluid back to reservoir 620 and back to the E-MAG pump 10, (100), (3000) via hydraulic line 621, or be in a mechanical energy producing state by engagement of control valve 630. Engagement of control valve 630 produces rotary motion at shaft 641 for controlled engagement to drive train 700. Fluid used to produce the rotary motion at shaft 641 is returned back to the fluid reservoir 620 which then feeds the input ports of cylinder 51. Therefore, while the present invention has been shown and described herein in what is believed to be the most practical and preferred embodiments, it is recognized that departures can be made therefrom within the scope of the invention. As an example, a very basic embodiment (not shown) would comprise only one electromagnetic means energized on and off in conjunction with the permanent magnet to produce the compression strokes. Therefore the invention is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent apparatus.
