FIELD: mechanical engineering.
SUBSTANCE: valve comprises a housing with outlet passage and inner cylindrical bores. The housing is made of two-step cylindrical bushing provided with inner axially aligned step bores. The periphery side of the larger step of the bushing is provided with three equidistant through outlet ports arranged parallel to its axis. The ports are separated with cross-pieces for permitting communication of the above-piston spaces with the inner space of the bushing. The flexible members of the collet are made of a split ring. The ring is connected with the bushing (housing) through cross-pieces. The cross-pieces are the guiding members for the plate valve gate mounted inside the housing. The plate valve gate cooperates with the seat, which is fit into the bushing. The greater step of the bushing is provided with the ring groove which is spaced from the edge. The smaller step is provided with the outer ring groove for permitting disassembling of the valve.
EFFECT: enhanced reliability.
