US 2003/0071087 A1 · DISPENSING APPARATUS WITH REMOTE CONTROL

Abstract

This dispensing apparatus includes a shut-off valve having an inlet chamber connected to a water supply and an outlet connected to a hose extending to a remote dispensing station. A valve element is provided which separates the inlet chamber from a control chamber but includes passages communicating between said chambers. A servo line connected to the control chamber includes a trigger cut-off valve at the end of the hose remote from the shut-off valve. The trigger cut-off valve is closed to permit pressure build-up in the control chamber to close the valve element and the trigger cut-off valve is opened to relieve pressure in the control chamber and open the shut-off valve and permit liquid to be dispensed.
