  • Distributor assembly for two-speed gerotor device
    Patent number: 8684710
    Abstract: A distributor assembly (12) includes a distributor housing (102) and a valve selector plate (104). The distributor housing (102) includes an axial bore (106) extending in an axial direction through the distributor housing. The valve selector plate (104) is disposed in the axial bore (106) and is rotatable around a rotational axis (130) parallel to the axial direction between a first orientation and a second orientation. The valve selector plate (104) includes a first substantially planar face (132), a second substantially planar face (134), axial passages (136) radially offset from the rotational axis (130) and extending through the valve selector plate (104) from the first face (132) to the second face (134), and at least one fluid blocking section (138) configured to block axial flow through the distributor assembly. Each fluid blocking section (138) is interposed between and radially aligned with the axial passages (136) with respect to the rotational axis (130).
