| description | A rotary fluid pressure device includes a gerotor gear set having a ring gear and a star gear orbitally moveable about a longitudinal axis relative to the ring gear. The star gear includes an annular spacer ring disposed at one end of the star gear. A brake pin is moveable along the longitudinal axis into and out of interlocking engagement with the annular spacer ring. The brake pin includes an outer surface for engaging an interior surface of the spacer ring. The outer surface of the brake pin and the interior surface of the spacer ring are each angled relative to the longitudinal axis to engage each other in a tapered engagement, to generate an axial force along the longitudinal axis to move the brake pin out of engagement with the star gear in response to a torque being applied to the star gear. |
