A hydraulic pressure multiplier having a housing, a bore in the housing and an outer piston slidably positioned within the bore. The pressure multiplier also includes an inner piston having a bore therethrough, the inner piston being positioned within a bore within the outer piston. An opening is provided through an end wall of the outer piston, and a mechanism is provided to selectively control hydraulic fluid flow into the bore within the outer piston. Hydraulic fluid first flows through the opening in the outer piston and through the bore through the inner piston to actuate a slave cylinder or a hydraulic piston within a brake. After a threshold pressure is reached within the slave cylinder, the valve closes and the outer piston is caused to move axially, thereby providing an increased hydraulic pressure within the slave cylinder.
A hydraulic pressure multiplier comprising a housing defining a cavity, an outer piston movably positioned within said cavity and including a sidewall and an end wall that together define an inner recess having an open end, a stationary inner piston received in said open end of said inner recess in said outer piston, a bore through said inner piston, an opening through said outer piston providing fluid communication between said cavity and said inner recess, a biasing mechanism applying a biasing force to said outer piston, and a mechanism to close the fluid communication between said cavity and said inner recess when said biasing force is overcome by pressure within said cavity.
A hydraulic pressure multiplier comprising:
