Title: Rotary engine driven by differential pressure
Inventor: YONEDA SHIN
IPC: F03G7/00
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To generate a movement by hydraulic pressure by opposing the propelling force of cylinders with force acting point of a resistant gear between a propelling gear engaged with a rack and, a discharge gear provided on the same axis of a reversely rotating gear engaged with transmitting gear fixed on the same axis of the propelling gear. SOLUTION: When cylinders 11, 12, 13 are equally pressurized by a pressurizing circuit 7, the cylinder 12 rotates a gear 19 via a rack 31 and rotates a propelling gear 16 clockwise via gears 18, 17. The propelling force of an opposing cylinder 13 is opposed to the propelling force of three times against a discharge cylinder 12 by rotating a gear 20 having a diameter less than a half of the diameter of the gear 18. Therefore, only the propelling force of the cylinder 11 is applied to move the axis of a gear 16 forward and the discharge cylinder 12 is axially moved backward by the rotation of the gear 19 to push out fluid in the cylinder 12 and to circulate it for filling cylinders 11, 13 therewith. The opposing cylinder 13 is axially moved forward by the rotation of the gear 20.  If the volume of the cylinder 11 is equal to that of the cylinder 12, an advancing differential movement mainly acted by hydraulic pressure can be realized without refilling fluid.

Abstract: PURPOSE:To prevent a rotary shaft from being subjected to excessive load, by such a simple structure that a ring shaped optical position detector is fixed to a rotary shaft so as to surround the same. CONSTITUTION:The luminous fluxes emitted from through-holes 9a, 9b rotationally move along with the rotation of a rotary shaft 9. By this rotational movement of luminous fluxes, the irradiation positions of light spots irradiating the ring inner peripheral surfaces of light position detectors 12a, 12b move and the intensities of lights obtained from both end parts of the detectors 12a, 12b change. Light detectors 13a, 13b receive the incidence of lights having intensities corresponding to the irradiation positions of light spots through reflectors 12a1, 12a2 and 12b1, 12b2 to send out electric signals. Said electric signals are inputted to operators 14a, 14b which, in turn, calculate the irradiation positions of light spots. A converter 15 calculates the absolute angle or angle-of- rotation displacement quantity of the rotary shaft 9 from the irradiation positions of the light spots to output the same. Because insensitive band regions are present in the detectors 12a, 12b, a part of an angle becomes impossible to measure but the measurement of said angle is performed by the position detector at the other side.
