The upper section includes a pressure chamber and an outlet chamber divided by a resilient material; a bore extending through the resilient material; and an inlet tube extending from the supply to the bore. A control valve controls the liquid flow through a hole providing communication between the pressure chamber and the lower part of the housing.
