<p>A pull-out faucet (10), comprising:
a hollow body (18) defining a longitudinal cavity (52) opening at a bottom end (54) and at a top end (48) and having an internally threaded side opening (74);
a right angle valve block (78) that is not integral with the hollow body (18), is disposed in the cavity (52);
a mixing valve cartridge (90) having an end that is positioned adjacent the side face (82) of the valve block and having an opposite end with a control stem (100);
water supply hoses (134,136) coupled to the valve block inlet passages (84);
a spray hose (16) having a first end coupled to the valve block outlet passage (86) and a second end coupled to a spray head (12);
the valve block (80) is sized so as to be able to be inserted through the side opening (74) and at least partially into the longitudinal cavity (52) so that the side face (82) is essentially parallel with the side opening;
the valve block (78) has a rectilinear shape and is retained from passing through the body cavity (52) by engagement of a peripheral flange (88) and a lip (76) inwardly directed at the inner end of a cylindrical section defining the side opening (74) of the valve block (78);
a three-hole rubber seal (97) is disposed between the side face (82) of the valve block (80) and the back of the mixing valve to seal the passages;
the outlet passage contains a rubber duck-bill valve (96) and a retainer (98);
the valve block (80) comprises an additional passage (99) in communication with the outlet passage (86);
the additional passage (99) includes a check valve (101) positioned by a retaining ring.</p> |
