摘要： A displacement assembly includes a rotor and a plurality of reciprocating members in engagement with the rotor. The displacement assembly further includes a ring assembly. The ring assembly defines a cam surface that is in engagement with the reciprocating members. The ring assembly has a first ring and an axially adjacent second ring with at least one of the first and second rings being adapted for selective movement relative to the other between a neutral position and a displaced position. The first ring has a first ring portion defining a bore that has an inner surface. The second ring has a second ring portion defining a bore that has an inner surface. A first circumferential portion of the inner surface of the first ring portion and a second circumferential portion of the inner surface of the second ring portion define the cam surface in the displaced position.
