ABSTRACT:
A hydraulically operated control valve with a cam member that pivots toward one or the other side of the neutral position in response to an operating member. A pair of push rods each with a piston interposed between the cam member and one of a pair of spool valves. A casing is provided wherein the cam member is mounted in the casing upper portion. A pair of piston chambers, each having an oil chamber formed at the top by the piston and a damper chamber formed at the bottom by the piston, are formed in the casing lower portion. A throttle in each piston communicates fluid between the corresponding oil chamber and the damper chamber. A pair of spring chambers each contain a spool valve at the center thereof. A pair of casing partition members separate the piston chambers and the spring chambers, and are adapted so the push rods extend through the center thereof. A pair of damping springs energize the pistons in the direction of departing from the partition members. A pair of check valves included on the casing partition members enable the hydraulic oil to move from the spring chambers to the damper chambers and prevent the hydraulic oil from moving from the damper chambers to the spring chambers.
