The valve member is provided with a diaphragm assembly 16 having a pressure chamber 50 for holding the valve member on the valve seat 26 on the upper part. A filter and a bypass orifice 58 within the diaphragm assembly 16 connects the inlet to the pressure chamber 50. The filter is mounted on the lower part of the diaphragm 18, and provided with a filter link 56 situated adjacently to the peripheral part. The rink 56 has a plurality of circumferentially isolated filter grooves 72, a channel 70 for connecting a groove communicating with the inlet, and an orifice allowing the channel 70 to communicate with the grooves 72 to provide a water conduit between the inlet and the pressure chamber 50.</p> |
