FIELD: machine building.
SUBSTANCE: flat spool valve pressed against the plate is made up of piston with flat surface in the form of figure of eight with four shutoff edges facing said plate. Shaped openings with sealing shoulders arranged along their edges and peripheral thrust ledges are made in said plate. Spool valve cylindrical part has barrel-like outer surface for centering relative to shaft blank groove communicated with pressure line. Preliminary spool valve hold-down to said plate is executed by spring arranged in shaft and spool valve blank groove.
EFFECT: higher operating performances, decreased sizes and higher reliability.
