ABSTRACT:
An hydraulic pressure converter comprises a differential piston which works in a stepped bore in a housing. A pressure space is defined in the housing at the end of a portion of the piston which is of smaller area so that reciprocation of the piston in the bore causes hydraulic fluid to be drawn into the pressure space through a first one-way valve and then pumped to an outlet through a second one-way valve. Reciprocation of the piston is accomplished by subjecting the piston to pressure from a pump to move the piston in a first direction away from a stop face and against the force in a compression spring so that hydraulic fluid is drawn into the pressure space. A valve assembly is operative to reduce the force urging the piston in the first direction when the displacement attains a predetermined value whereafter the spring is operative to urge the piston in a second opposite direction to force fluid to the outlet from the pressure space.
