ABSTRACT:
A valve actuating assembly (10) including an input housing (12) and a circular drive wheel (14) rotatably supported by the input housing (12) and having a cylindrical outer periphery with a plurality of parallel teeth (16). A drive gear (22) is rotatably supported by the input housing (12) and is in meshing engagement with the teeth (16) of the drive wheel (14). The input housing (12) has a first pair of cable guide tubes (24) disposed opposite to one another on opposite sides of the drive gear (22). An output housing (28) is identical to the input housing and supports a driven wheel which is identical to the drive wheel (14). A first conduit (30) is connected to and extends between one of the guide tubes (24) of the input housing (12) and one of the guide tubes of the output housing (28). A second conduit (31) is connected to and extends between the other guide tubes (24) of the input housing (12) and the other guide tube of the output housing (28). An endless flexible motion transmitting core element (38) is slidably disposed in the first and second conduits (30, 31) and the guide tubes (24) and is entrained about the drive (14) and driven wheels. The core element (38) moves longitudinally to rotate the drive (14) and driven wheels in a closed all-tension system.
