ABSTRACT:
A hydraulic fluid pressure energy translating machine is provided with hydrostatic pressure-balancing means which communicate with the primary port to balance hydrostatic forces acting on the barrel during operation of the machine to maintain an optimum bearing clearance between the head and barrel, thereby controlling fluid leakage and maintaining adequate lubrication and support at this interface.
