发明名称 Rotor valve and seal
摘要 ROTOR VALVE AND SEAL 5 A rotor valve (10) having a rotor seal (34) containing a centrally disposed opening (52) for directing an external pressure (Pe) to a rear surface (35) of the seal for applying a sealing force against a sealing surface (36). A projection (38) of the seal surrounding the opening is disposed within a bore (40) formed in a rotor (14) of the valve. An O-ring seal (44) defines the portion o the rear surface exposed to the external pressure. The rotor may be 10 supported on one end by a bearing assembly (80) and may be open at the opposed end for receiving incoming water. Circumferentially distributed slip-surface plugs extend radially beyond the diameter of the rotor to support the rotor along an interior surface (39) of the valve body (12).
