FIELD: agricultural engineering, in particular, equipment used in hydraulic control systems.
SUBSTANCE: hydraulic distributor has pump charging line arranged outside of distribution zone and zone of supplying of liquid to consumers. Charging line is extending to discharge part of system via openings and grooves made in casings of operating sections and via bores in slide valves. Discharge line openings are extending tangentially to grooves in operating section casing and are made dead. Inlet and outlet centers of adjacent dead openings are arranged at opposite sides of operating section casing. Slide valves are equipped with annular bores and are positioned for displacement in said casings. During operation of hydraulic distributor upon shifting of slide valve to working position, oil pressure does not create side pressure upon casing wall and force upon central side surface of slide valve.
EFFECT: increased efficiency by eliminating section casing deformation and jamming of slide valve.
