Abstract:
An apparatus for transferring and applying pressure to fluids, comprising:a housing having an internal housing cavity containing a working fluid;a drive shaft communicating with the internal housing cavity;a first rotatable cam disk having a first end communicating with the drive shaft and a second end, the second end having a surface which is slanted relative to a plane perpendicular to the drive shaft;a plurality of pistons in the housing cavity, each piston having a first end communicating with the slanted surface of the first cam disk and a second end away from the first cam disk;a plurality of piston chambers in the internal housing cavity, each piston chamber housing a piston and having first and second piston cavities, the first end of the piston being in the first piston cavity and the second end of the piston being in the second piston cavity, the second piston cavity containing a system fluid;one or more piston seals positioned on each piston separating the working fluid from the system fluid;one or more fluid supply channels communicating with the piston chambers; andone or more fluid outlet channels communicating with the piston chambers;wherein axial movement of the pistons effected by rotation of the cam disk pressurizes system fluid in the second piston cavities of the piston chamber, and forces the system fluid into the one or more fluid outlet channels.
