Abstract

See full text

A hydraulic machine (1) such as a pump or motor includes a working section (6) such as a gerotor. A spool (3) is rotatable about an axis (4) within a bore of the machine housing (2). The spool includes hydraulic fluid directing passages that enable operation of the machine. The spool includes first and second axially spaced apart circumferential grooves (14, 15). A plurality of first axial grooves (16) extend in intersecting relation with the first circumferential groove and a plurality of second axial grooves (17) extend in intersecting relation with the second circumferential groove. The first and second axial grooves are arranged in alternating relation about the circumference of the spool. The circumferential grooves are bounded radially inwardly by respective bottom walls (19, 22) that have a greater radial distance from the axis with axial proximity to the intersecting grooves.
