Abstract

PURPOSE: To prevent generation of abnormal sound at the time of operation of a valve body, which is coupled to an elastic partition film of a sealed chamber unit, by providing the valve body with a shield for regulating the flow of water issuing from an orifice.
CONSTITUTION: A skirt-shaped rubber plate 22, which has a through-hole 22a receiving a head portion 21a of a rubber valve 21, is provided between an edge portion 21b of the rubber valve 21 and the inner surface of an outer casing 10 provided with an adjustment screw 13. Thus, water jet from an orifice 13a and flowing along the rubber valve 21 is collected within a cavity defined by the rubber plate 22. When water within the cavity exceeds a predetermined quantity, it forces away the rubber plate 22 as shown by broken lines and is discharged through an outlet. In this way, abnormal vibrations and abnormal sound which are produced simultaneously with the jetting of water from the orifice 13a are absorbed by the water within the cavity in the rubber plate 22 serving as buffering member.
