Abstract
A valve stack assembly comprising a manifold having an inlet channel connected to a source of air. A plurality of inlet tubes each having an inner end communicating with said inlet channel and the outer end of each tube projects outwardly of the manifold and is sealed within an inlet passage of a valve. An annular collet is disposed in each inlet passage and receives the inlet tube and the collet is designed such that the tube can be freely inserted in the collet but cannot be freely withdrawn unless the collet is moved axially inward to a release position. Each valve also includes an outlet opening which receives an outlet tube mounted in the manifold and each outlet tube is connected to a transverse manifold passage which in turn is connected through a fluid line to a working element.

In a valve stack assembly, a manifold having an inlet channel connected to a source of fluid, a plurality of first tubes each having an inner end communicating with said channel and each having an outer end projecting outwardly of the manifold, a plurality of valves each having an inlet passage connected to the projecting end of one of said tubes, a collet disposed the inlet passage of each valve and having a central opening to receive the tube, each collet being constructed and arranged such that the tube can be freely inserted in the collet but cannot be freely withdrawn, and release means associated with each collet for releasing engagement of the collet with said tube on inward axial movement of said collet relative to said valve.
A valve stack assembly, comprising a manifold having an inlet channel connected to a source of fluid, a plurality of first tubes each having an inner end communicating with said channel and each having an outer end projecting outwardly of the manifold, a plurality of valves mounted in side-by-side relation on the manifold, each valve having an inlet passage connected to one of said first tubes and having an outlet passage, a collet disposed in the inlet passage of each valve and having a central opening to receive one of said first tubes, each collet being constructed and arranged such that the first tube can be freely inserted in the collet but cannot be freely withdrawn, release means associated with each collet for releasing engagement of the collet with the first tube on inward axial movement of the collet relative to the valve, a plurality of second tubes each having an outer end projecting outwardly of the manifold and received within the outlet passage of a valve, and outlet means in the manifold and connected to each second tube for delivering fluid being discharged through said outlet passage to a working site.
A valve stack assembly, comprising a manifold having an inlet channel connected to a source of fluid under pressure, a plurality of parallel tubes disposed generally normal to the axis of said inlet channel, each first tube having an inner end communicating with said channel and having an outer end projecting outwardly of said manifold, a plurality of valves disposed in side-by-side relation on the exterior of said manifold, each valve having an inlet passage and at least one outlet passage, a collet disposed in the inlet passage of each valve and having a central opening to receive one of said first tubes, each collet being constructed and arranged such that the first tube can be freely inserted in the collet but cannot be freely withdrawn, release means associated with each collet for releasing engagement of the collet with said first tube on inward axial movement of the collet relative to said valve, a plurality of second tubes each having an outer end projecting outwardly of the manifold and received within the outlet passage of a valve, said manifold being formed with a plurality of apertures extending transversely of said inlet channel, the inner end of each second tube being received within an end of an aperture, the opposite end of each aperture being connected to a fluid conduit for supplying fluid to a working element.
