摘要：The valving element of a valve has an axially projecting tubular extension with an open-ended socket for one end section of a shank which has a larger-diameter cylindrical portion in the deepmost portion of the socket, a smaller diameter cylindrical portion adjacent the open end of the socket, and a concave annular surface between the two cylindrical portions. The concave surface abuts a split ring which has a circular cross-sectional outline and is held in the socket as a result of deformation of the extension close to the open end of the socket. The annular surface abuts the adjacent portion of the external surface of the split ring, the same as the adjacent portion of the internal surface of the extension.
