TITLE Actuator Assembly for Remotely Controlling a Valve. ABSTRACT OF THE DISCLOSURE A valve actuating assembly including an input housing and a circular drive wheel rotatably supported by the input housing and having a cylindrical outer periphery with a plurality of parallel teeth. A drive gear is rotatably supported by the input housing and is in meshing engagement with the teeth of the drive wheel. The input housing has a first pair of cable guide tubes disposed opposite to one another on opposite sides of the drive gear. An output housing is identical to the input housing and supports a driven wheel which is identical to the drive wheel. A first conduit is connected to and extends between one of the guide tubes of the input housing and one of the guide tubes of the output housing. A second conduit is connected to and extends between the other guide tubes of the input housing and the other guide tube of the output housing. An endless flexible motion transmitting core element is slidably disposed in the first and second conduits and the guide tubes and is entrained about the drive and driven wheels. The core element moves longitudinally to rotate the drive and driven wheels in a closed all-tension system.
