Abstract: One described embodiment of a device for predetermining the quantities of liquid delivered by a meter, said meter having a valve to control the delivery and means for measuring the quantity of liquid delivered, comprises a rotatable cam and a transmission having a variable transmission ratio adapted to be driven by said quantity measuring means for rotating said cam. A valve closure controlling lever having a portion engageable with said cam is arranged for closing said valve in at least one angular position of said cam upon completion of a constant angular displacement by said cam from a stop position. A selector is provided for choosing a desired transmission ratio and thus selecting a predetermined quantity of liquid to be delivered while the cam rotates through said constant angular displacement. The lever is temporarily inhibited from on the valve upon opening of said valve to rotate said cam from said at least one angular position through said constant displacement thus permitting the start of a new delivery of the same predetermined quantity by just opening the valve.
