ABSTRACT:
A rapid acting flow limiting valve is provided for an autoclave processing system. In this environment, each of a plurality of parts is placed in immediate proximity with a tool, then impressed into congruent engagement with the tool by an overlying vacuum bag, the interior of the vacuum bag being subjected to a vacuum via a vacuum manifold connecting all of the parts to a source of the vacuum, the interior of the vacuum bag being subjected to pressure. A first conduit leads from the chamber of the valve housing to the interior of the vacuum bag for its associated part, and a second conduit leads from the chamber to the vacuum manifold. An annular seal is positioned concentrically with an opening from the chamber into the first conduit. A flexible disk-shaped floating piston diaphragm assembly is peripherally fixed to the housing and is movable between an open position distant from the seal and a closed position engaged with the seal to thereby block flow through the first conduit. An annular spring concentric with the annular seal biases the floating piston diaphragm assembly toward the open position. Should the vacuum bag for a second part rupture, which would cause pressurized fluid flow to be introduced into the vacuum manifold toward the valve associated with the first part, the diaphragm assembly for that valve is moved to the closed position preventing pressurized fluid flow into the vacuum bag for the first part.
