ABSTRACT:
A valve is disclosed for distributing pressurized fluid, such as air, from a single supply source to a plurality of rotatable screwcapping heads. The valve includes a stationary member axially aligned with a rotatable shaft which has a first surface with first and second arcs formed therein, both of the arcs having an equal radius. The stationary member also has an inlet passage connecting the supply source to the first arc and an outlet passage connecting the second arc to the atmosphere. The valve further includes a support member which is securely fixed to the rotatable shaft and a rotational member which is axially aligned with the rotatable shaft and rotatably fixed to the support member. The rotational member has a first surface which is positioned adjacent to the first surface of the stationary member and has at least two slots formed therein which are arranged on a predetermined radius equal to the radius of the first and second arcs. The rotational member also includes a plurality of radial passages connecting each of the slots to one of the screwcapping heads. Compression springs are positioned between the support member and the rotational member for urging the rotational member into constant contact with the stationary member and to prevent the leakage of pressurized fluid therebetween.
