Abstract
Abstract A faucet of the type for controlling the flow of fluids therethrough in which the rotational action of the faucet valve stem within the body of a faucet, together with limiting control of axial displacement of the valve stem, provides for control of fluid through the faucet, and wherein effective seal means between the valve stem and other fixed portions of the faucet are simplified and essentially free from wear, thereby eliminating the normal compression and wearing problems inherent in faucet construction.

Total Claims: 14
Claim 1
Independent Claim
287 words
A faucet to control the volume flow of fluid, comprising: a housing having a cylindrical hollow chamber therein and having an inlet port and an outlet port to said chamber, and having a restricting aperture of a size substantially less in diameter than the inlet port connecting the inlet port with the hollow chamber, a stem member rotatably disposed within the housing and being concentric with said inlet port and said hollow cylindrical chamber and having a body portion of substantially the same diameter as the cylindrical chamber and further having an opening in the body portion intermediate of the restricted aperture portion of the inlet port and the outlet port of the housing chamber, resilient seal means in the restricted aperture portion housing yieldingly and continuously urged and juxtaposed with the body portion of the stem member and forming the seal for the inlet port to the chamber, said restricted aperture having the seal means therein axially parallel to but nonconcentric with the inlet port and said seal means further having an opening therein for fluid transfer therethrough, rotational movement of the stem resulting in movement and positioning of the opening in the body portion of the stem with respect to the opening in the seal means permitting alignment of the opening in the seal means with the stem opening, from a closed relatiOnship to an aligned and completely open relationship and thereby permitting variation in the rate of flow of fluid through the faucet a closure member concentric with the cylindrical hollow chamber and with the inlet port for retaining the stem member, and an O-ring between the stem member and hollow housing providing sealing means for preventing fluid pressure directly on the closure member.

Claim 7
Dependent Claim
232 words
