ABSTRACT:
An improved linear fluid motor system, which is adapted to be driven by pressurized hydraulic fluid from a hydraulic pump, includes a piston rod having a first head interacting with product fluid and a second head interacting with hydraulic fluid, a first spool valve and a second spool valve interacting with the second piston head to control a third spool valve which reverses the displacement of the piston rod at its limits of travel, a first accumulator, and a second accumulator for cushioning abrupt pressure changes in the hydraulic fluid, a heater for heating the hydraulic fluid, a control valve for controlling the product fluid pumping rate of the system, interconnections for connecting the various components of the system, stops for defining the various configurations of the system, a detent mechanism for restraining the third spool valve in its switching configurations, and a coaxial conduit for conveying the hydraulic fluid between the hydraulic pump and the system whereby the product fluid is pumped from an input port to an output port. A modified embodiment includes integrally formed interconnections.
