ABSTRACT:
The valve for dispensing liquids which contain or are free from gas, more especially drinks containing carbon dioxide, from containers, comprises a housing with a socket which can be fitted on to the container opening, a riser duct which opens into the socket and to which is connected a riser extending into the container, a dispensing duct which extends to the lateral face of the housing and is connected to said riser duct, and a valve member which is displaceable in a bore between a closed position and an open position. According to the invention the device is characterized in that the bore has rotatably arranged therein a cam carrier which partially encloses the valve member and of which the cam or cams cooperating with at least one pin of the valve member have a pitch region, the pin or pins are held by spring force in abutment with the cam or cams of the cam carrier, pin support bearings are provided in the pin position at the upper end of the pitch region and the valve member, with support of its pins on the pin support bearing, is axially fixed and, with release of its pins from the pin support bearing, is axially displaceable. When a gas-pressurized liquid is dispensed by this device, the release of the dissolved gas and thus the formation of froth is avoided.
