Abstract: A metering valve for water faucet that is triggered at the water discharge by a light touch on the trip stem so that the hand that triggers the valve is ready at the washing position at the start of the water flow. The disclosed metering valve consists of a trip stem which penetrates through the valve outlet port to the exterior of the valve. There is a pressure chamber wherein the pressure controls the open and closure of the valve. The pressure in the pressure chamber is determined by means of feed and bleed.

A light touch on the trip stem causes the bleed to open and a depressurization in the pressure chamber. This opens the valve and starts a metering cycle. After the trip stem is release, the bleed is blocked again and the pressure chamber starts to recover its pressure slowly through the feed flow path.
