Patent ID: 7143997

Claim:
A plug assembly for a faucet, the plug assembly comprising: a casing adapted for engagement with the faucet and having two open ends respectively defined in two opposite ends of the casing; a cylinder securely received in the casing and having an open end and a closed end which has multiple outlets defined through a face of the closed end; an isolator securely received in the cylinder and having a tapered through hole defined through the isolator and slits defined in a top face of the isolator to communicate with the outlets of the cylinder; a top ring supported by the cylinder to sandwich the isolator with the cylinder, the top ring having a hole defined through a bottom face of the top ring; a control rod slidably received in the tapered through hole of the isolator and the hole of the top ring and having multiple cutouts defined in an outer periphery of the control rod to alternately communicate with the hole of the top ring; a push rod securely connected to a distal end of the control rod to sandwich a friction ring with the control rod, the push rod being movable relative to the cylinder and the friction ring engaging with an inner periphery defining the tapered through hole; an adjusting device sealingly combining the push rod, the control rod, the isolator and the top ring to selectively adjust deformation of the friction ring such that the engagement of the friction ring to the inner periphery of the tapered through hole is adjusted such that after the push rod is moved upward relative to the cylinder to have communication among the hole, the slits, the cutouts, and the outlets, the friction of the friction ring to the inner periphery of the tapered through hole determines time duration of the push rod returning to its original position to shut the communication among the hole, the slits, the cutouts, and the outlets and thus water supply from the faucet is blocked after the adjusting device is engaged with the top ring.
