ELECTROMAGNETIC VALVE Russian patent published in 2004 - IPC

FIELD: utilizing and controlling streams. SUBSTANCE: device has stop, bushing and plug. Said three elements are in water- tight connection. Rigidity of aiding compression spring is less than rigidity of oncoming compression string. Open side passage of on cylindrical surface of rotor is made linear-screw. Stop and coupling rod have at least one auxiliary passage. First orifice of auxiliary passage is placed on end surface of stop on the side of rotor inside contour of bushing passage. Second orifice is placed on end surface of stop on the side of valve body inside contour of lock passage. Coupling rod and rotor form longitudinally non-detachable assembly. Connecting element of stop is made in form of threaded connecting pipe. Aiding compression spring is placed between rotor and plug. At the end of passage contrary to the stop, ring-shaped stop is placed. EFFECT: lowered acoustical noise during valve operation and increased speed of valve operation. 2 dwg
