Abstract:

The instant invention is a positive shutoff valve for use on emergency vehicles so as to maintain air within a reservoir tank allowing immediate movement of an emergency vehicle upon start up. The shutoff valve is operated by a switch located in the operator's compartment of the emergency vehicle providing movement of a solenoid located in the shutoff valve which is biased in a normally closed position. A manual bypass lever is provided should the electric solenoid fail to operate correctly. The shutoff valve positively maintains air within the reservoir tank and is monitored by a low pressure switch and alarm sensor which will indicate low air pressure in the reservoir tank even when the vehicle is in an off position.
