Patent ID: 7174913

Claim:
A gas tap for a cooking appliance comprising: an elongated tap body ( 2 ) with a conical plug ( 3 ) received in a central housing ( 2 a ) in the tap body to regulate a gas flow (G) outlet, a hand-operated rotary shaft ( 4 ) coupled to the conical plug, a cover bushing ( 5 ) covering said central housing, and a return spring ( 13 ) urging the shaft axially towards the cover bushing, wherein the actuating shaft is rotatable through an angle (A) in either of two directions, the shaft being provided with a radially oriented transverse pin ( 6 ), drawn by the shaft ( 4 ) from an initial rotation locking position ( 7 ) corresponding to the gas flow supply “OFF”, to two spaced maximum and minimum gas flow shaft positions ( 8 ), said cover bushing ( 5 ) being tubular with a cylindrical part ( 5 b ) provided with a circular base ( 5 c ) sealing the tap body ( 2 ) and a peripheral edge ( 10 ) engaged in said central housing ( 2 a ), wherein said circular base ( 5 c ) in the cover includes a sliding surface ( 11 ) extended over an arc corresponding to said angle (A) of rotation of the shaft and provided with a series of indentations serving as a friction means ( 12 ) that are coextensive with shaft rotation angle (A) and that contact the radially oriented pin ( 6 ), said friction means producing an acoustic or tactile indication of the shaft ( 4 ) rotation while the tap ( 1 ) outlet is opening.
