ABSTRACT:
A first pressure-intensifying apparatus includes a working cylinder having a working piston mounted within it and reciprocally movable by the application of working fluid alternately to opposite sides of the working piston. The working piston in turn drives a high-pressure piston movably mounted within a high-pressure cylinder. The flow of pressurized working fluid to the working cylinder is controlled by a control valve. The control valve receives pressurized fluid from a source of working fluid and directs the fluid to the working cylinder and then back to a working fluid reservoir or tank. The control valve includes a valve body and has a spool movably mounted therein that is movable between a first position in which fluid is directed to one side of the working piston and a second position in which fluid is directed to the other side of the working piston. The spool is designed to maintain a constant volumetric flow of fluid from the source to the tank at the first and second positions and all positions in between. In order to accomplish this, a series of slots are formed in the surface of the spool to divide the flow of fluid between the source and the working cylinder and the source and the tank at the intermediate positions of the spool in a predetermined fashion. Also, preferably, the construction of the working piston and the high-pressure piston permits for limited radial movement between the working piston and the high-pressure piston to compensate for misalignments between the working cylinder and the high-pressure cylinder.
