Rotary hydraulic engine having oppositely disposed pistons in a scotch yoke assembly

Patent ·
OSTI ID:5503832
A rotary hydraulic engine is described comprising, in combination; frame means; crankshaft means supported by aid frame means in substantially fixed relation therewith and having an eccentric crank portion; housing means encircling the crankshaft means and being rotatable relative thereto, the housing means defining a plurality of pairs of cylinders disposed in laterally opposed sets such that each cylinder is laterally opposed to and co-axial with an opposed cylinder; a piston slidingly disposed within each of the cylinders; a scotch yoke assembly having a pair of discrete slide members each of which interconnects the pistons disposed within the laterally opposed set of cylinders and has cooperative relation with the eccentric crank portion so as to effect tandem movement of the interconnected pistons and thereby effect relative movement between the housing means and the crankshaft means; external valve means operatively associated with each of the cylinders so as to enable selective application of fluid pressure to the pistons in a manner adapted to effect predetermined sequential movement of the pistons and associated scotch yoke assembly, thereby imparting rotary motion to the housing.
