ABSTRACT:
A housing for a discharge valve includes a hollow cylindrial socket which projects in the radial direction, and in which a siphon an actuating pin for control of the valve stopper is mounted in a leakproof manner in a ball-and-socket joint arrangement. A spherical part enclosing an intermediate portion of the actuating pin is received in a ball socket recess in a holding element, which is snapped onto the socket in a leakproof manner. The ball socket recess has on the outer side a spheri-zone type sealing surface on which an O-ring slides. A set of fingers of the holding element partially enclose the spherical part and press it with a specific force against the sealing surface.
