Abstract
A fluid transfer apparatus utilizing a slanted cain disk to oscillate and rotate a set of pistons arranged in a circle. Channels associated with the pistons and piston housing effect the transfer of fluid from a first location to a second location, as well as the pressurization or depressurization of the fluid, during movement of the pistons. The apparatus can be used as a high-pressure fluid pump, a fluid-powered motor, a fluid distribution valve, or another fluid transfer device.
