FIELD: transport. ^ SUBSTANCE: invention relates to machine building, namely, to steering transfer mechanisms. Proposed valve consists of body accommodating continuous-action operating valve with two inlets from two pressure lines, two lines of supply for additional using equipment, one line of proportioning pump and two control lines. Besides, said valve has four adjusting edges, one control the flow from first pressure line to first line of first additional using equipment. Second edge controls proportioning pump supply flow. Third edge controls flow from second pressure line to proportioning pump supply line. Fourth edge controls flow from second pressure line to second line of additional using equipment. Priority valve incorporates also operating valve return spring and check valve with its outlet built in proportioning pump supply line from third adjusted edge. Proportioning pump supply line from third adjusting edge and check valve are arranged in operating valve body. ^ EFFECT: simple and compact design. ^ 3 dwg |
