Publication number: 20160237662Abstract: A control valve includes a valve body and a valve seat, which is fixed at a bottom of the valve body, and has a roof with a spout thereon. Both side edges at front of the spout have intervals including a water inlet duct. The lateral arcs of the two inlet ducts are designed to taper the inlet duct. Also the upper sides of two inlet ducts connect with the roof, and the relative position on the roof of each duct has a limber hole to let water down into the inlet ducts. The two inlet ducts are used as an entry which penetrates the lateral arc to let each cold and hot water through into the ducts. An annular pad is outside of cold and hot water inlets to cover the ducts. The two intervals, which locate on the backsides of outlet, extend a ladder-shaped positioning pin respectively.Type: ApplicationFiled: February 13, 2015Publication date: August 18, 2016Applicant: HAIN YO ENTERPRISES CO., LTD.Inventor: Chia-Po Chang

Patent number: 8869816Abstract: A mixed water control valve for a faucet includes a valve housing, a control unit, and a balance unit. The valve housing has a mounting seat which has a receiving chamber and two water inlet holes. The balance unit includes a fixed sleeve secured in the receiving chamber, a pressure regulating sleeve movably mounted in the fixed sleeve, a balance baffle mounted in the pressure regulating sleeve, and two elastic members each mounted in the pressure regulating sleeve and each biased between the balance baffle and the mounting seat. Thus, the balance baffle is compressed between the elastic members which provide a buffering force to counteract a larger pressure applied on the balance baffle, so that the pressure regulating sleeve is moved smoothly and stably without producing resonant noise in the faucet.Type: GrantFiled: December 13, 2010Date of Patent: October 28, 2014Assignee: HAIN YO Enterprise Co. Ltd.Inventor: Chia-Po Chang

Patent number: 7918241Abstract: A control valve for a faucet includes a valve housing, a hollow valve seat, two sealing gaskets, at least one water outlet channel, a rotation plate, a control unit, two mounting seats, a fixed sleeve, and a movable sleeve. Thus, the movable sleeve is movable in the fixed sleeve to control the water flow rate of the mixed cold and hot water to the optimum value to regulate and stabilize the water pressure automatically so as to provide a pressure balance effect so that the mixed water flowing from the water outlet channel is kept at a constant temperature, thereby providing a comfortable sensation to a user.Type: GrantFiled: December 5, 2007Date of Patent: April 5, 2011Assignee: Hain Yo Enterprises Co., Ltd.Inventor: Chia-Po Chang
