ELECTRIC VALVE OF HIGH PRESSURE Russian patent published in 2011 - IPC F16K31/02 

FIELD: machine building.

SUBSTANCE: electro-magnetic valve of high pressure consists of case with coil. The case has an outlet central branch and through channel for working medium. Internal surface of the case is made as surface of a truncated cone with a ring from the side of one end. The ring is made out of non-magnetic material. Surface of the truncated cone is conjugated with surface of an anchor of the electric magnet. The anchor corresponds to a truncated cone with through channels for working medium and with a cylinder guiding lug on its vertex. The lug is located in a bushing. The bushing is fabricated out of non-magnetic material and is spring loaded on the end opposite relative to conic part of the anchor with a shut-off element of a cylinder type. The shut-off element is made in the central part of the anchor base of the electric magnet and interacts with a seat. The seat is arranged in the central part of a case cover. On the back side of the cover there is made an outlet branch for working medium. A ring out of non-magnetic material is installed in the base of surface of the case truncated cone.

EFFECT: reduced power consumption, weight and dimensions of electro-magnetic valve of high pressure.
