ABSTRACT:
The former art provides multi stroke hydrostatic motors, which perform at a single revolution of the rotor multiple inward and outward strokes of the pistons. A high torque was thereby obtained. The invention discovers, that the known multi stroke motors are still too heavy, obtain small overall efficiencies and their power per size and weight is limited because the known motors failed to provide means to carry the tangential loads by fluid pressure power. The invention increases the power and efficiency of multiple stroke motors by the provisions of control means to control the flow of fluid pressure into pockets open to the piston faces and cylinder walls, whereby the torque of the rotor is transferred from the pistons to the cylinder walls by pressure in fluid in the pockets. The invention also provides means to enlarge the stroke of the pistons in a given size and weight of the device. The fluid pressure pockets make high pressures possible and the angles of inclination of the guide faces can be increased. The torque of the device of a given size becomes multiplied and the efficiency of the device increases by the application of the provisons of the invention.
