Abstract: The invention discloses a pressure balanced mixing device comprising a balanced module including a fixed tube and a movable element including a cylinder which connects with two cups and is between the two cups blocking a cold-water inlet and a hot-water inlet of the fixed tube, wherein each cup has an opening and a base plate, each opening is in communication with a cold-water outlet and a hot-water outlet of the fixed tube. The cylinder has two side walls and two connecting rods. One of the two side walls is separated from the base plate of one of the two cups by a cold-water space, the other side wall is separated from the base plate of the other cup by a hot-water space. The cold-water space and the hot-water space are in communication with the cold-water inlet and the hot-water inlet of the fixed tube, respectively.

Abstract: A mixed water control valve for a faucet includes a control unit, two mounting seats and a balance unit. The control unit includes a valve housing, a rotation plate and a control handle. The balance unit includes a fixed sleeve and a pressure regulating sleeve. The pressure regulating sleeve is movable in the fixed sleeve by a pressure differential between the two mounting seats to control the water flow rate of the cold and hot water of the two mounting seats and to regulate the water pressure automatically so as to provide a pressure balance and to stabilize the temperature of the mixed cold and hot water in the valve housing so that the mixed water flowing from the valve housing is kept at a constant temperature.

Abstract: A faucet includes a faucet body, a control knob, a follower and a switching valve. The faucet body has a water inlet, a water outlet and a switching port. The switching valve includes a driven rod moved with the control knob, a sealing plate having a plurality of connecting holes, a pressure release plate detachably pressing the sealing plate, and an elastic member mounted between the sealing plate and the pressure release plate. Thus, the switching valve can release the water pressure in the faucet body automatically so that the sealing plate is moved downward by its gravity to detach from the switching port, and the water inlet, the switching port and the water outlet are connected at a normal state to allow passage of water to prevent the water from being introduced into the shower head at the next usage.

Abstract: A control valve for a mixed water faucet includes a housing, two sealing gaskets, a control shaft, a ceramic unit, a sealing ring, a sleeve, a pressure balance unit, an adjusting cock, and a fastening member. The pressure balance unit includes a bushing and a spindle. The ceramic unit includes a fixed plate, a movable plate, and a protective jacket. Thus, the movable plate is rotatable relative to the fixed plate to change the connection area between the water outlet chamber of the movable plate and the water inlet chambers of the fixed plate so as to regulate the water flow rate and the mixed proportion of the cold water and the hot water.

Abstract: A control valve includes a housing, two sealing gaskets, a shaft, a protective jacket, a fixed plate, a movable plate, a sleeve, a pressure balance unit, and an urging screwing member. Thus, the movable plate is rotated by operation of the shaft without producing deviation or loose displacement so as to balance the water pressure and control the water output and temperature exactly. In addition, the movable plate is driven by the shaft to rotate relative to the fixed plate without producing friction and wear between the movable plate and the fixed plate, thereby enhancing the lifetime of the control valve.
