BALANCE PLATE ASSEMBLY FOR A FLUID DEVICE

摘要

A fluid device (10) includes a displacement assembly (16) and a balance plate assembly (14) disposed adjacent to the displacement assembly (16). The displacement assembly (16) includes a ring (28) and a rotor (26) disposed in a bore (34) of the ring (28). The ring (28) and rotor (26) cooperatively define a plurality of volume chambers (50). The balance plate assembly (14) includes a housing (84) that defines a cavity (86). A balance plate (86) is disposed in the cavity (86). The balance plate (86) includes a first end surface (130) and an oppositely disposed second end surface (132). The balance plate (86) is adapted to move axially between a first position (200) in which the second end surface (132) of balance plate (86) abuts a first end face (31) of the ring (28) to a second position (204) in which the second surface (132) of the balance plate (86) is recessed in the cavity (86).
