Abstract
A valve having a valve body with an elongated opening therein and having a first end and a second end. A valve member is slidably disposed in the elongated opening. First, second and third ports are in fluid communication with the opening in the valve body at times. One of the first, second and third ports have a supply of fluid under pressure connected thereto. A first passage is disposed in the valve body and leads from the first port to the second end thereof. A second passage is disposed in the valve body and leads from the second port to the second end thereof. A third passage is disposed in the valve body and leads from the third port to the second end thereof. An actuator body is adapted to be connected to the valve body and has a cavity therein. The actuator body has a first end adjacent to the second end of the valve body. An actuator is disposed in the cavity. The actuator has a first side and a second side and is moveable between a first and a second position thereof for moving the valve member. A fluid passageway is disposed in the actuator body and leads from the first end of the actuator body to a position on the second side of said actuator and is adapted to be selec…
