Abstract: The present invention provides a device for turning off a pump. In operation, when the device is activated there is vacuum pressure in a syrup chamber. A diaphragm acting in response to the vacuum causes a piston assembly in the syrup chamber to move in the one direction (e.g. right), thus compressing a W-shaped spring in the air chamber. As the piston assembly moves, a spring holder of the W-shaped spring also moves to the one direction. As the W-shaped spring is compressed over and passed the most compressed position, the W-shaped spring moves a valve assembly in the air chamber to an opposite direction (e.g. left) and blocks a hole in a spool that otherwise allows air to pass through the air chamber to activate the pump. When the air is stopped, this turns off the pump.
