Abstract
Abstract An electromotive force and fluid pressure force controller apparatus for connecting and disconnecting the forces to devices activated and deactivated thereby in programmed conjunction with one another comprising a case having a slide chamber and at least one slide in the chamber movable between the ends of the case. Electrical contacts are located on and in the case adjacent to at least one side of the case and slide. The slide has sliding and/or snap-acting switch means aligned with the contacts for interconnecting the contacts and disconnecting them. Prongs are mounted on the case for connection to electrical supply and bussbars lead from the prongs to the contacts. The case has ports in at least one wall for transmitting fluid force into and out of the case. These ports are aligned with the travel of the slide. The slide has a channel maze valve engaging the interior of the ported wall of the case which is connected to and moves with the slide over the ports to interconnect and block communication between the ports. A flexible block having apertures aligned with the ports overlies the outside of the ported wall. Tubes lie in the apertures of the block. Clamp means surmount the flexible block and engage the case to compress the block into sealed engagement with the case, ports, and tubes to isolate each tube and its connected port from the others. Several slides may be nested in the case and individually moved and/or moved by another slide to control the forces singly or in combination. The ports, contacts, mazes, switch means, and slide are organized relative to one another and the various positions of the slide so that electrical and fluid force are connected and disconnected to the devices powered thereby as desired in the system programming.
