Abstract: A valve assembly comprising a valve body having a cylindrical chamber therein, a shaft extending diametrically across the chamber, and a flattened substantially elliptical valve on said shaft. Either the valve body or the valve, or both, are formed of elastically deformable material. Preferably, the valve chamber is provided with a separate generally cylindrical elastically deformable liner. The valve has a centrally located opening extending therethrough from edge to edge. The valve assembly is assembled by positioning the valve in the chamber and by inserting the shaft through an opening in the valve body into the chamber, through the valve and into an opening in the valve body at the opposite side of the chamber. The elasticity of the valve body and valve is such as to permit longitudinal insertion of the shaft and to also provide a driving engagement between the shaft and valve and to provide an efficient shaft bearing by the valve body after the shaft has been inserted. In addition, the relatively softer liner provides an effective seal around the shaft, and an efficient sealing action with the valve.
