ABSTRACT:
A hydraulic force multiplying device has a housing having an inlet port connected to a source of hydraulic pressure and an outlet port, an input rod and an output rod, one end of each of the input and output rod being slidably connected with one another within the housing, a free piston slidably disposed between the outer circumference of the input rod and the inner wall of the housing and dividing the interior of the housing into an inlet side oil chamber and an outlet side oil chamber, the free piston being associated with the output rod, a passage formed in the input rod for connecting the two oil chambers, and a valve for controlling oil flow in the passage. The valve consists of a valve member and a valve seat provided respectively on either the input or the output rod and the other of the input and output rods. The valve is formed to allow the relative movement between the input and output rods in the valve closing direction with the valve member engaging with the valve seat.
