Abstract
A combination valve including a metal sleeve and a valve body. The valve body is formed of a resilient material and insert bonded or vulcanized to the metal sleeve and includes a cylindrical elongated member defining a passageway therethrough and an annular umbrella portion integrally extending from the elongated member. The elongated member is disposed within the metal sleeve and has converging flexible lips. The metal sleeve includes a plurality of prongs at one end and the valve body includes a top surface. The prongs of the metal sleeve extend to the top surface of the valve body, whereby the valve can be press-fitted into location without damaging the valve body. Between the prongs of the metal sleeve are gaps which permit the molding material to flow from the umbrella portion to the elongated member during the molding of the combination valve.
