VALVE MODULE FOR SUPPLY OF FLUID, UPPERMOST GASEOUS, MEDIA Russian patent published in 2012 - IPC F16K1/44 F16K31/06 F02M21/02 

FIELD: machine building.

SUBSTANCE: valve module comprises a bushing (7) of a valve, where a valve anchor (9) is installed with a stop element (11), arranged to control a fluid medium flow between an inlet side (3) and an outlet side (5) with the possibility of its directed axial displacement relative to an element (15) of the valve forming a valve seat (13) and fixedly installed in the valve bushing (7). A sealing device (21, 21', 21") is made with at least two circular sealing ledges (22, 22', 22") and is arranged relative to at least one throughput hole (17) so that in the closed position of the valve module (1), at least one throughput hole (17) is located between the sealing ledges (22, 22', 22"). The sealing device (21, 21") is arranged with two separate sealing ledges (22, 22"). The sealing device (21, 21', 21") is fixed on an end surface (10) of a stop element (11) or an end surface (16) of a valve seat (13) by the method of vulcanisation, casting onto the base or adhesion.

EFFECT: improved tightness of a valve module and its increased service life.
