Abstract
The subject invention relates to a fluid pressure intensifier (32) for increasing the pressure of an incompressible fluid and comprises a fluid reservoir (112) supplying fluid to a cylinder housing (72). The housing (72) includes first inlet (88) and outlet (90) cylinders extending between opposite ends (74,76) of the housing (72) and slideably receiving first inlet (96) and outlet (100) pistons therein. Second inlet (92) and outlet (94) cylinders are spaced parallel to the first cylinders (88,90) and further extend between the housing ends (74,76) for slideably receiving second inlet (98) and outlet (102) pistons therein. The first pistons (96,100) are forced in unison axially through the housing (72) to increase the pressure of the hydraulic fluid in the first outlet cylinder (90). A fluid channel (156) allows passage of the fluid from the first outlet cylinder (90) to the second inlet cylinder (92) and thus forces the second pistons (98, 102) in unison in opposing directions through the housing (72) to further increase the pressure of the fluid in the second smaller outlet cylinder (94). The fluid is then expelled from the housing (72) through an outlet (151) to an actuating device.
