SUPPLY SYSTEM OF INTERNAL COMBUSTION GAS ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention can be used in system supplying internal combustion engines with liquefied petroleum gas. Proposed supply system contains gas electromagnetic valve one lead-out of winding of the valve being designed for connection to automobile frame, and reducer-evaporator whose second stage chamber accommodates diaphragm of relief device. Chamber of second stage of reducer-evaporator is provided with lever installed for turning around axle brought out of the limits of diaphragm. One arm of said lever is coupled with diaphragm axle, and other arm is provided with permanent magnet. Magnet is installed for interaction with contacts of fixed sealed-contact reed relay open in initial position. First contact is electrically connected with housing, and second contact is connected to lead-out of winding of electromagnetic gas valve disconnected from housing. System can be furnished with relay with two contacts open in initial position. Sealed-contact reed relay can be furnished with third contact closed in initial position with second contact. Third contact of sealed-contact reed relay is connected to first contact of relay whose second contact is connected to automobile frame. Winding of relay is made parallel to winding of stator relay. EFFECT: prevention of spontaneous leakage of gas when engine is not operating owing to deenergizing of winding of gas electromagnetic valve. 2 cl, 1 dwg
