    摘要： A hydraulic control valve which is equipped with two direction change-over valve groups individually having traveling change-over valves, and first and second hydraulic pumps corresponding to those direction change-over valve groups. The traveling section valve of one of the change-over groups is equipped with a communication valve. Each section valve has its valve body formed therethrough with signal conduits individually extending perpendicular to spool bores. The two traveling section valves are formed with annular grooves in spool bores positioned to correspond to said signal conduits. The individual working machine section valves other than the traveling section valves are formed with annular grooves in the spool portions corresponding to the signal conduits to provide the communications between the upstreams and downstreams of the signal conduits only when the spools are in their neutral states. If the working machine section valves are operated while actuating the traveling section valves, the signal conduits are shut off in accordance with the movements of the spools to raise the pressures in the operation signal conduits. This raised pressure actuates the communication valves so that the discharged oil of the second hydraulic pump may merge through the communication conduits of the two direction change-over valve groups and may be introduced into the traveling section valves short of the oil.

    摘要： A pressure selector valve (13) is provided between a hydraulic motor (1) and a directional control valve (5) to connect one of the main conduits (4A), (4B) on a high pressure side to a high pressure conduit (14) while connecting the other of the main conduits on a low pressure side to a low pressure conduit (15). As an inertial body approaches a stop position, a spool valve (16) is switched to an open position (e), bringing a branch passage (14A) of the high pressure conduit (14) into communication with the low pressure conduit. When the pressure difference between the main conduits becomes small, the pressure selector valve is automatically returned to a neutral position to cut off communication between the main conduits, suppressing a reversing movement of the hydraulic motor so that an inertial body can be brought to a stop smoothly.

    摘要： A spool type directional control valve switches flow of oil discharged from an oil hydraulic pump to a hydraulic actuator, and decreases internal leak of a cylinder. Two sets of separated cylinder passages are formed on a valve body provided with a main spool, and a nonleak valve is provided across them. The nonleak valve is equipped with a main passage switching puppet having a throttle on the nose, a spring for energizing it to a close side, a pilot poppet for controlling pressure of a spring chamber in which the spring is enclosed, and a piston for operating the poppet.
