Abstract: The invention relates to an actuating device for a tap on a beverage decanting installation. The tap 1 bears a plug-in receptacle 5 with a non-return valve 8-10 of a connection 6, 7 for a pressurized gas pipe. Fitted on to the plug-in receptacle 5 is a casing 13 formed with connecting channels and connecting chambers 16, 18, 19, 21, 22, 28, 29 for the supply of a pressurized gas to an actuating piston 32 disposed in a chamber 30 for an actuating member 3 of the tap 1. When the casing 13 is fitted on, the non-return valve 8-10 accommodated in the plug-in receptacle 5 is retained in the open position by a tappet 16 of a connecting channel 18, so that the actuating piston 32 can experience pressure via another valve 25, 26, 27 actuable by a rocking lever 40. The other valve 25, 26, 27, constructed as a non-return valve, is actuated via a tappet 34 which takes the form of a valve and via which the chamber 30 of the actuating piston 32 can be relieved of pressure.

Abstract: A beverage dispensing tap of the type wherein a compensator sleeve inside the housing maintains a shut-off valve open for supply of the beverage into the housing of the tap. The invention simplifies the structure of the tap by replacing a number of sealing rings at the inlet of the housing by a single gasket which seals the compensator sleeve against the housing, provides valve seat for the shut-off valve and also serves as a seal at a union connecting the inlet of the housing to a connection pipe for feeding the beverage into the housing.
