ABSTRACT:
A constant flow valve for low flow rates employs a tire valve assembly which is threadably received within the downstream end portion of an axial passageway formed in an elongated inlet tube. The tube is received within a stem portion of a first part of an internal housing. A movable wall which is at its periphery clamped between a base portion of such first part and a bell portion of the second part, divides the interior of said housing into upstream and downstream chambers. The stem portion of the tire valve assembly extends into the upstream chamber and contacts the movable wall. A biasing spring is located in the downstream chamber and exerts a biasing force against the movable wall which is in turn transmitted to the control stem. A considerable length of relatively small internal diameter, high flow resistance tubing is coiled about the inlet tube and the stem portion of the first housing part. The upstream end of the tubing communicates with the upstream chamber and the downstream end of the tubing communicates with the downstream chamber. The tubing performs the dual functions of a pressure reducing restriction between the two chambers and a flow rate averager. An external casing surrounds the coil of tubing and at least portions of the inlet tube and the internal housing and a plastic filler material is provided in the exterior casing about the components enclosed thereby. An outlet passageway leads outwardly from the downstream chamber to an outlet fitting.
