<p>PCT No. PCT/US87/00800 Sec. 371 Date Feb. 16, 1988 Sec. 102(e) Date Feb. 16, 1988 PCT Filed Apr. 7, 1987.A cartridge assembly for converting a single-handle faucet from a ball-type valve to a cooperating plate valve. The cartridge includes an outer body member (10) having one fixed valve plate (16) and one movable valve plate (19) and lever means (23) for controlling the relative motions of the plates. The body (10) has a substantially cylindrical upper portion and a lower portion (11) defined by inclined, semi-spherical surfaces. A pair of converging inlet passageways (12) communicate with throughbores (17) formed in the fixed plate (16) to control fluid flow through the assembly and to an outlet (7). The cartridge is designed to be introduced into the chamber (2, 3) of a faucet valve body (1) normally utilized with a ball-type valving member without requiring alteration of the faucet valve body (1) to thereby introduce flow regulation members composed of flat valve plates (16, 19) manufactured from hard, wear-resistant materials.</p> |
