MECHANISM FRICTION PARTS LUBRICATION SYSTEM OIL FEED TRANSMITTER Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed transmitter is designed for monitoring oil delivery into mechanism friction parts lubrication system. Transmitter has magnetically-operated contact and magnetic field source placed in magnetic circuit which is provided with two parts of pole shoes. Magnetically-operated contact is installed between pole shoes of first pair, and pole shoes of second pair are made in form of unions made of ferromagnetic material secured on magnetic circuit. They are placed in oil feed circuit and hermetically interconnected by non-magnetic material coupling in inner space of which spring-loaded ferromagnetic shutoff member is installed forming check valve, together with seat, made on lower part of first union. Spring-loaded part of shutoff member is located in second union, and at least part on non-magnetic pusher is arranged inside first union. Pusher provides displacement of shutoff member in direction from first union to second union in case of presence of oil flow. EFFECT: improved reliability of mechanism. 1 dwg
