VALVE UNIT Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: valve unit includes mounting plate, several distributors located near each other and at least one control valve engageable respectively with each distributor. Running through mounting plate are air supply and discharge passages and recess for electric mounting device which is parallel to passages; on side where distributors are connected, plate has connecting openings in accordance with the connection diagram. Control valve operated by electromagnet is coupled with plug connected by means of base of connector in shaft of electric mounting device. Control valve and electromagnet are located in common housing whose lateral mating surface adjoins end side of engageable distributor. Valve unit includes plate checker to which distributor adjoins on one side and connecting sides of mounting plate adjoins it on other side. Checker has through holes. Base of connector projects from lower side of housing of control valve and enters the hole in mounting plate; base is sealed up by means of seals. Projecting contact flags of base are in contact with contact terminals of electric mounting device. Two control valves may be located in housing axially one after other or vertically one above other. Housing with control valves is closed at the top with cover where at least one seat of valve is located which is engageable with sealing surface of electromagnet core; passages for supply, discharge and control air are formed in cover and in housing of control valves. EFFECT: enhanced reliability. 9 cl, 2 dwg
