The present invention provides a novel faucet with a non-circular slider assembly to which a resilient seat-washer is attached. In a preferable embodiment of the invention the slider assembly has a hexagonal cross-section. In embodiments of the invention the slider assembly is driven by a rotatory stem operated with a handle. The rotatory stem is provided with a helical groove mating with a faucet body of a complementary shape so that upon rotation of the stem the slider assembly is advanced towards or withdrawn from a sealing seat. Thus, when the handle of the stem is rotated by a user, the stem and the hexagonal slider assembly associated with it, are moved by the interacting force generated between the pair of helical threads, towards or away from the seat depending on the rotation direction.

[ I claim:] [7.] A method of assembling a washer-saving valve comprising:providing a valve body having an inner surface and a seat;providing in said inner surface of said valve body a helical groove, andproviding concentrically with and broached through said helical groove a non-circular bore in said inner surface of said valve body;providing a valve stem with a helical ridge complementary to said helical groove, said valve stem having a seat-facing end;providing a slider assembly having a first and second end so that at least a portion of said slider assembly has a cross-section complementary to said broached non-circular bore and so that a seat-washer may be removably attached to said second end;rotatably attaching said first end of said slider assembly to said seat facing end of said valve stem;attaching a seat-washer to said second end of said slider assembly; reby:said non-circular slider assembly has a seat-washer thereon and fits slidably but non-rotatably within the broached non-circular bore and is in a driven relationship to the seat-facing end of the valve stem, so that when the valve stem is advanced by rotation through the valve body, the slider assembly is prevented from rotating by the non-circular bore so that the seat-washer borne upon the slider assembly does not rotate against the seat upon contact therewith.
