ELECTRIC PNEUMATIC VALVE Russian patent published in 2016 - IPC F16K31/02 

FIELD: construction.

SUBSTANCE: invention relates to multi-purpose accessories and can be used in pneumatic hydraulic systems of various industries. Electropneumatic valve includes a housing in which there are interconnected bolt and piston. Control cavity is interconnected with inlet cavity via discharge valve controlled by electromagnet. In connection of the gate and the piston is installed coaxially arranged and spring-loaded retainer with possibility of back-and-forth axial movement. Said retainer one end with projections on the side of the spring fitted in grooves of the collar made on the rod of the gate lock rod from turning about the axis. At the other end of said retainer are arranged ledges, one side of which is inclined, and the other one is located parallel to axis. Above the other end of the retainer is engaged with mating similar projections located on piston face, thus fixing the from turning gate relative to piston.

EFFECT: technical result-simplification of assembly process valve gate travel adjustment, reliable fixation against turning gate relative to piston to provide the required degree of gate sealing.
