<p>A mechanism for covering and protecting operating parts of a mixing faucet that has a bidirectional control lever (10) which extends through an opening in its cover (11) and moves about a single center. A semi-spherical surface (11a) of the cover abuts a thin semi-spherical cap (15) having an exterior and interior surface (15a) and (15b) having the same center of rotation as the lever. The cover's semi-spherical surface substantially corresponds to the semi-spherical cap's interior surface. The semi-spherical cap (15) covers the opening (10) and is able to slide over the semi-spherical surface of the cover due to its identical spherical curvature. Structurally the cap is separate from the control lever and is transverse to it. The cap (15) makes contact with a rim of the window (17) of an outer hood (16). The hood (16) is mounted about the cover (11) and able to slide there against and into the space underneath the hood. Cap (15) and the hood (16) can be economically produced and mounted onto the valve. The cap and hood can be made from plastic materials or molded metallic laminates.</p> |
