  • Patent number: 4790354
    Abstract: A three-way normally closed relay valve is provided for selectively effecting a control action in response to pressure of a pilot fluid. A tubular valve body defines a central valve chamber for housing a valve member manually manipulatable into a relay open position for initiating service. A lower piston affixed to the end of the valve member is subjected to pilot fluid pressure, and moves the valve member axially for controlling the flow of fluid between inlet, outlet, and vent ports in the valve body. An orifice in the piston intermittently establishes communication between a pilot pressure inlet port and a chamber within the valve body. The restricted orifice cooperates with a fixed seal to trap pilot pressure above and below the piston as the movable piston passes the fixed seal toward the relay closed position, and thereby prevents the valve member from moving in response to pilot pressure.

  • Patent number: 4499921
    Abstract: A three-way air valve whose housing has connection openings for a compressed air power line, a line running to the load and an air let-off opening, the load opening being joined up with the power opening in one position of the valve and with the air let-off opening in the other position thereof. The housing having the power inlet opening, the load opening and the air let-off opening has an axial hole running through it from end to end for taking up a liner, which may be pushed in from one end of the housing and has airways for the air moving through the valve. Furthermore, the liner has a valve lip. Within the inner hole of the liner, which is open at the end nearest to the valve lip, there is the valve spool which has a valve seat for use with the valve lip. The valve spool is acted upon by the driving rod guided in the housing and by a spring which urges it axially.

  • Patent number: 4476890
    Abstract: A pressure control valve includes a relief poppet biased by a first spring into contact with a seat and an anti-void poppet biased by a second spring into contact with a seat independently of the relief poppet, so that a sharp response of the valve is ensured for a void control or anti-void function and the interference of the anti-void function with a relief function is prevented. Part of the check poppet which faces a relief passageway is formed with a shoulder to direct an outlet portion of a pilot passageway parallel to the axis of the relief passageway, thereby eliminating high frequency vibration of the pilot poppet or generation of noise due to the interference of pilot and main flows of fluid.

  • Patent number: 4420011
    Abstract: A pilot valve is disclosed having a piston actuating a valve element shiftable between a first and second positions. The piston is comprised of two concentrically arranged pistons, the larger piston having an internal bore with two sections of staggered diameters and a smaller, correspondingly shaped second piston inserted in the concentric internal bore. A single O-ring on the bottom of the second section of the first piston annularly mounted around the second section of the second piston seals the piston chamber from a fluctuating sensed fluid pressure. The first piston has a longer upper bore section than the second piston. A spacer is placed at the juncture of the first and second sections of second piston so as to enable the first and second piston to act in unison in actuating the valve element. In this mode, the effective surface area of the piston is equal to the diameter of the larger piston or of the O-ring.

  • Patent number: 4418716
    Abstract: A two-way flow valve includes a valve body having a cavity and a stem longitudinally moveable therein which establishes two separate fluid flow paths through the cavity in the body from first and second inlet ports to a common outlet port. A spring biases the stem to a first position in which fluid flow is allowed along a first one of the paths and obstructed along the other. When a closure is applied to the valve, the stem is moved against the spring bias to a second position in which fluid flow is allowed along a second one of the paths and obstructed along the first path.

  • Patent number: 4418711
    Abstract: A valve insert is designed for use in valve casings for making up air valves which may be controlled by air under pressure or by a mechanical system and which are normally open or closed. The valve insert is made up of a housing, which is open at its two ends and has two groups of outwardly running openings, which are separated from each other by an outer gasket ring. The valve further has a spool with sealing rings. One end the spool has a hook having a neck part which is spaced from the spool axis and a hook end which is normal to the neck part. The end part of the hook extends past the axis of the spool a distance which is at least equal to the distance of the neck part of the hook from the axis of the spool. The diameter of the hook end is somewhat smaller than the distance between the hook end and the end face of the spool. The sealing rings are so placed that, on operation of the valve and motion of the spool, one inner sealing ring is moved over one group of openings.
