Patent EP-0011360-A1 (EP)
Inventor: SHOWALTER MERLE ROBERT
IPC: F02M33/06
Filed: 1979-09-24
Abstract: A vortex fuel air mixer is positioned between the air throttle (4) and the intake manifold of an engine. Part (20,22) of the expansion flow velocity past the air throttle (4) flows tangentially into the vortex chamber (18) of the mixer, providing angular momentum which drives the flow into a vortical pattern. The flow streamlines within the vortical flow form into a generally irrotational flow pattern which swirls from the outside wall of the vortex chamber (18) inwardly to a central vortex chamber outlet (32). This outlet feeds the engine intake manifold. Centrifugal forces in the swirling flow fling fuel droplets to the outside wall of the vortex chamber (18) (in the manner of a cyclone scrubber). This liquid fuel must evaporate in order to leave the vortex chamber.

Abstract: A valve assembly especially for a breathing apparatus comprises a housing 14, an inlet for admitting gas into the housing from a source of gas at a superatmospheric pressure, a movable valve member 21 which is capable of closing the gas inlet and which, in operation, is acted upon, at least when ist is closed or nearly closed, by a force resulting from the pressure difference between the higher pressure gas upstream of the inlet and the lower pressure gas in the housing 14, the effect of which force is to tend to move the valve member 21 to open the gas inlet, and means 16 responsive to the difference between the pressure in the housing 14 and the ambient pressure, the pressure-responsive means 16 being so connected to the valve member 21 that, if the pressure in the housing 14 exceeds the ambient pressure, at least by a certain amount, the pressure-responsive means 16 exerts a force on the valve member 21 which tends to cause the valve member to move to close the inlet

Abstract: The armrest (12,14) incorporates a parallelogram linkage (24, 30) which permits the armrest (12, 14) to be raised or lowered through a series of parallel positions and locked in any one against downward movement. A ratchet (40) and pawl arrangement permits the armrest (12, 14) to be tilted while in various fixed positions of the linkage (24, 30), or, simultaneously as the linkage is moved. Movements of the arm or linkage in a lowering direction are controlled by a pair of manually operated buttons which operate separate, spaced apart pawls which engage different teeth on a single ratchet member (40). The buttons are not required for upward movement. The armrest (12,14) can function as such or can be lowered to be flush with the seat so as to extend the seat width. It can also be tilted downwardly to a hip supporting position or upwardly to a vertical storage position. Various cam and stop arrangements restrict movements of the armrest outside a preferred range.

Abstract: In this machine, vanes (5, 6, 7) are supported in such a manner in a rotatable drum (4) that they simultaneously rotate about the axis of rotation and oscillate about this axis in the longitudinal direction, separating various gas chambers of variable size in a housing from one another. The housing consists of the planar base and cover plates (1, 2) and a swung wall (3) connecting these plates and standing perpendicularly between them, which wall (3) touches the central drum (4) tangentially or in short conformity at three points (12) and is at a maximum distance from the drum at three points (13) opposite the three contact points. The diameter of the housing, measured through the axis of rotation, is always equal to the length of the vanes (5, 6, 7). The drum (4) and thus the drive shaft connected to it are set in rotation by pressure of the gas on the part of the vanes (5, 6, 7) standing proud of the drum (4). Bore holes and indentations (14, 15) in the drum (4) and openings (9, 10, 11) in the plates (1, 2), which release the gas paths alternately at the right time, are used for controlling the inlet and outlet flow of the gas. <IMAGE>

Abstract: An internal combustion engine has an orbital inner body or piston member (21,200) working in a housing (10, 204) and eccentrically connected with a power output shaft (36,38) to rotate the latter while orbiting within the housing. 
     A compact, efficient design is obtained by associating each pair of interfitting lobes (16,28; 18,30; 20,32), formed respectively in the housing and inner body and together providing a combustion chamber (70) and an exhaust chamber (72), with an intake and compression chamber (56) formed by a recess (42, 44, 46) in the inner body and a slidable element (46) accommodated therein. During orbital movement of the inner body, the slidable element (46) slides into sealing engagement with the associated lobes to form a sealed space containing the chambers (70,72). The housing, inner body and slidable element (46) feature an arrangement of grooves (86, 88, 90) which, during the orbital movement, cause fluid to be admitted to the chamber (56) for compression therein, then admit the compressed fluid to the combustion chamber, and thereafter exhaust the expanded fluid from the exhaust chamber (72). Each inner body lobe includes a surface (70a) parallel to the axis of eccentricity whereby combustion forces act normal to the axis in order to attain enhanced efficiency of power transfer to the shaft (36, 38).
