  • Patent number: 7159845
    Abstract: A bearing module for a pintle valve including a pintle bearing, bearing spring, and two-part housing. The bearing has an axial face for sealing against an inner axial surface of the housing. The bearing diameter is less than the diameter of the housing, permitting the bearing to float radially. The housing fits into a port in the valve body and also extends over an axial surface of the body, thus forming a seal against the wall of the port and the surface of the body. The bearing spring, preferably a wave washer, is compressed within the housing as the two housing parts are assembled to form the module. In a currently preferred embodiment, the housing further comprises a coking shield extending along the surface of the pintle shaft within the valve port to reduce the tendency for coking gases to enter the bearing module.
