Hydraulic control valve for remote receiver

A hydraulic control valve for transmitting fluid under pressure from a fluid pressure source to an actuating line of a receiver, said control valve comprising a housing, a bore in said housing, first means carried by said housing for coupling one end of said bore to a fluid pressure source and second means carried by said housing for coupling an opposite end of said bore to an actuating line, an actuating element slidably mounted in said bore, a manually movable operating member operatively connected to said actuating element for shifting said actuating element in said bore with movement of said operating member causing said actuating element to slide in said housing to transmit fluid under pressure from said first means to said second means, fluid flow passage means through said actuating element for placing said first means and said second means in fluid communicating relation, a pressure relief valve carried by said actuating element normally closing said fluid flow passage means and for relieving excess pressure at said second means, and cooperating synchronizing means carried by said actuating element and said housing for automatically opening said fluid flow passage means at a predetermined point in the shifting of the actuating element.
