FIELD: mechanical engineering.
SUBSTANCE: control unit for hydraulic systems comprises pressure and drain ring spaces which are made of ring bores and embrace the housing. The housing is provided with the race with sealing members. The through cylindrical openings provided in the housing receive slide valves with rods. The cylindrical openings intersect the spaces. The cross-pieces between the drain and pressure spaces are defined by the intersection of the cylindrical openings in all cylindrical opening. The cross-piece is defined by the height at which the slide valve overlaps the pressure space. The working passage is in communication with the drain passage.
EFFECT: simplified structure.
