Abstract
An eccentric ring porting system for hydraulic pumps
of the type having a rotating cylinder block. The
rotating cylinder block (46) has a flat annular port face (52) with
a small cluster of regularly spaced cylinder ports (80) in the
face circularly arrayed about the axis of rotation (32) of the
cylinder block (46). A ring valve element (110) has a ring seat
surface (120) held flush against the cylinder port face (52). The
axis (36) of the ring seat surface (120) is eccentrically offset from
the axis of rotation (32) of the cylinder block (46), and the
cylinder ports (80) are uncovered inside of the inner edge of
the ring seat surface (120) for output porting of the pump and
outside of the outer edge of the ring seat surface (120) for
inlet porting of the pump.
