摘要： A hydraulic pump assembly including a first pump, a second pump, a shaft, and fluid lines is disclosed. The first pump includes a first piston assembly. The second pump including a second piston assembly. Each piston assembly of the first and second pumps includes a cylinder and a piston slidably disposed in the cylinder. The shaft connects the first pump to the second pump and is configured to displace the pistons within the cylinders of the first and second piston assemblies. The fluid lines fluidly couple the first piston assembly with the second piston assembly to form paired piston assemblies. The first piston assembly is phase shifted from the second piston assembly.

摘要： It is a positive displacement, non-pulsating hydraulic pump with a double action piston that is non-reciprocating and generates fixed volume with high pressure. The piston moves in one direction through the inside of a toroid chamber in which two movable walls isolate the loading and unloading cavities. When a movable wall opens to give way to the piston the other movable wall splits two cavities within this chamber. When hydraulic pressure is supplied it works as a hydraulic motor, which allows the use of high efficiency and performance of the piston in the production of electric energy. It also substantially reduces size and considerably simplifies the mounting of the piston's operating mechanism. All of this improves performance of the hydrostatic transmission.

摘要： A hydraulic motor of variable cubic capacity with retractable partitions sed in radial grooves in a rotor. The partitions are each integral with a guide pin trapped in an endless cam groove of approximately ovoid shape in a surface stator. The partitions also pass through radial grooves in a sleeve housed in a circular groove in the rotor in order to slide therein parallel to the axis of the motor. A reaction member passes through an aperture in the stator in order to remain in frictional contact with an end surface of the sleeve. The driving force comes from oil pressure in a circular groove defined between the end surface of the sleeve and the surface of the stator. The sleeve and reaction member slide jointly.
