  • Patent number: 5204652
    Abstract: A solenoid valve comprising with a plunger which is readily and accurately adjustable to various heights whereby the solenoid is able to function with virtually all fluid flow control systems. The solenoid includes an elongated base which may have multiple threads to accommodate a variety of connectors and a bleed screw formed to be minimally disruptive to the electromagnetic field. A measurement standard, in the form of a cylinder and piston combination, is shaped to fit within the solenoid body and accurately determine the desired length of the specific plunger. The piston is mounted to move in the cylinder and, in conjunction with the cylinder, to assume the exact length required for the plunger within the solenoid to function correctly in operating the valve. The plunger is adjustable which allows the height thereof to be precisely and securely set to the height determined by the measurement standard.
