ABSTRACT:
An apparatus for supplying fluid under pressure, such as compressed air, to movable using devices, includes a feed line having tap points spaced along it, with a tap valve at each tap point. A connection unit for connecting the feed line to the user is movable along the feed line and can receive fluid at any tap point. As the connection unit slides into place at the tap point, the tap valve automatically opens to supply fluid. Each valve has a rotary or slide-type valve member movable between open and closed positions, which is always exposed to equal fluid pressure all about it so as to require only a small force to actuate the valve. The valve member is tubular and open-ended and extends parallel to the feed line. Both mechanical and magnetic means for actuating the valve member are disclosed.
