摘要： An improvement to reduce the size of a directional control valve by providing a plurality of pilot spool valves in a single valve casing. A plurality of valve mechanisms are juxtaposed in a monolithic valve casing by individually inserting valve members in a plurality of parallel valve bores provided in the valve casing. A plurality of cylinders corresponding to the valve bores are pierced in an intermediate plate mounted on the valve casing from that face which comes in contact with the valve casing. The cylinders communicate with each other by means of grooves cut in the aforementioned contacting face and open into the atmosphere through a relief port. The adjoining cylinders are thus brought closer, and the valve bodies are driven by pilot fluid pressure that act on the pistons fitted in the individual cylinders.

摘要： The solenoid actuator of this invention is provided with a magnetic flanged member for reinforcing the bobbin structure and reducing the magnetic resistance having a flanged portion and a cylindrical portion and inserted said cylindrical portion, whose inner surface is coated with a thin film made of feeble or non-magnetic and wear-resistant material, into the central aperture in a non-magnetic reel-shaped bobbin wound therearound with an energizing coil, and a movable core inserted into the central aperture in the bobbin is guided along the cylindrical portion of the flanged member, whereby the frictional abrasion caused by the sliding movement between the cylindrical portion of the flanged member and the movable core is suppressed and the frictional force caused by the uneven abutment between the outer surface of the movable core and the inner surface of the cylindrical portion of the flanged member is made relatively small to suppress the reduction of the attraction force between the stationary core and the movable core and thereby attaining a smooth operation of the movable core.

摘要： A changeover valve has a valve body formed on a valve rod in such a manner as to be detached from forming molds and easily and securely mounted on a projection formed on the valve rod. The valve body is bisected at the center of the projection on the valve rod and has a mechanism for effectively preventing the downward penetration of compressed air from the edge of the bisected segment. The changeover valve has a valve rod carrying a valve body that switches the flow of fluid between individual ports by coming in and out of contact with two opposite valve seats. The valve rod has an annular projection on which the valve body of elastic substance is to be fitted. While a first annular groove is provided on each side of the annular projection, a second annular groove is cut at the center of the annular projection. The valve body is bisected into two segments that are individually mounted on both sides of the second groove. Each valve body segment has an integrally formed first and a second fitting projection adpated to fit in the first groove and the common second groove. The second fitting projection on the bisected valve body segment has an annular flange extending inward toward the valve rod. The flange has a bore whose diameter is reduced to a minimum within such a limit as will not interfere with the detachment of forming molds.

摘要： In a change-over valve, a valve member consists of a poppet type closure member. A pair of supporting rods are connected to the opposite end portions of the closure member. Guide members made of synthetic resin are connected to the opposite end portions of the supporting rods in order to guide the valve member upon changing over in the directions of fluid flow passages. The guide members prevent the closure member of the valve member from inclined and unstable seating against the valve seats.
