Abstract: A valve includes a housing having two inlets and an outlet formed in a bottom panel, a seat secured in the housing and having two ports and an aperture aligned with the inlets and the outlet of the housing. A rotary member is rotatably received in the housing, and engaged onto the seat, and includes a bore communicating with the aperture of the seat, and two slots selectively communicating with the ports of the seat when the rotary member is rotated relative to the housing and the seat. The seat and the rotary member are made of porcelain materials to make a water tight seal without spring members.

Abstract: A faucet housing includes two barrels each having an inlet port for receiving hot and cold water, and an outlet port. A receptacle and two conduits are coupled between the barrels. One of the barrels has a partition for separating the barrel into two spaces and for communicating with the conduits. A casing is disposed in the other barrel and the receptacle and has a bore for receiving a tube and a valve member. One or more check valves are engaged in either or both of the inlet ports of the barrels for preventing backward water flow and for maintaining water pressure in the housing.

Abstract: A water control valve device includes a housing having a cap and a receptacle member fixable together. The cap includes one or more inlet orifices and greater openings for receiving water, and one or more check valves each has an inner casing engaged into the orifice and an outer peripheral flange engaged in the opening of the housing, and each having a port for receiving water. The check valve includes one or more inclined surfaces for forming a closable mouth which is openable when water flows into the casing and which may be closed for blocking water.

Abstract: A water control valve device includes a housing having one or more inlet orifices and greater openings for receiving water, and one or more check valves each having an inner casing engaged into the inlet orifice of the housing and an outer peripheral flange engaged in the opening of the housing, and each having a port for receiving water. The check valve includes one or more inclined surfaces for forming a closable and openable mouth which is openable when water flows into the casing and which may be closed for preventing the water from flowing out of the housing.

Abstract: A valve includes a housing having a chamber and two inlets communicating with each other, two casings received in the chamber of the housing and each having a bottom orifice and an upper port and a side aperture communicating with each other. A valve seat is slidably received in the apertures of the casings and has two openings communicating with the inlets of the housing, and a valve member is slidably engaged in the valve seat. A number of sealing members may be easily and solidly engaged between the casings and the housing and a cover for forming an excellent water tight seal.

Abstract: A valve device includes a housing having two inlets and two outlets. A valve stem is rotatably received in the housing and includes an annular swelling formed between two peripheral chambers which are communicated with the outlets of the housing. The valve stem has an aperture and a passage communicating the inlets with the peripheral chambers respectively for allowing the water from the different inlets to flow out through the respective outlets directly without being mixed within the housing and the valve stem.

Abstract: A valve includes a housing having one or more pairs of opposite notches and one or more pairs of opposite channels. A plate has a stem rotatably engaged through the housing and has a pair of curved oblong holes. A base has two gaskets for communicating two inlets to the curved oblong holes of the plate. The base has one or more pairs of opposite juts and one or more pairs of opposite hooks engaged with the notches and the channels of the housing for allowing the housing and the plate to be rotated for 180 degrees relative to the base and to be secured to the base.

Abstract: A mixing valve includes a housing having two inlets for receiving cold water and hot water. A valve member is secured in the housing and includes a membrane that may be easily secured between two casings. A valve stem is slidably engaged in the casings and has a middle portion secured to the membrane. The valve stem has two valve elements for engaging with the valve seats of the casings and for blocking the hot water when the cold water is not supplied to the housing. One or more control valves may be exchangeably secured to the valve member.

Abstract: A valve includes a base having a chamber and two inlets communicating with the chamber, and a cover engaged on the base. The base includes a peripheral groove formed around the chamber for engaging with a sealing member and includes six notches communicating the peripheral groove with the chamber. A valve seat is secured in the chamber and a valve member is slidably engaged in the valve seat. Three sealing rings are engaged between the valve seat and the housing and engaged with the notches of the sealing member for making a water tight seal for the valve.

Abstract: A faucet and filter assembly includes a faucet secured to one end of a base which has two partitions for separating the interior of the base into three spaces. A valve is threadedly engaged in the base for engaging with one of the partition and for controlling the water from one space to the other. A bolt is secured to a lower side portion of the base for securing an outlet. A filter barrel is secured to the upper side portion of the base and coupled to the outlet for filtering the water and for allowing water to flow out through the outlet.

Abstract: A valve for a faucet includes a housing having two retainers and one stop extended upward from the upper peripheral edge. A control stem may control the water flowing in and out of the housing. A cap has two orifices for engaging with the retainers and includes a radially extended annular flange having a notch for engaging with the stop and for solidly securing the cap to the housing. A sealing ring is engaged between the cap and the housing for making a water tight seal between the cap and the housing and for preventing water from flowing out of the housing.

Abstract: A mixer control valve comprises a base, a cover covering the base, and a washer, a cylinder and a control shaft disposed between the base and the cover. The mixer control valve couples with a water volume control valve. The water volume control valve has a control rod and a plurality of positioning rods. The cover has a first outlet, a second outlet, a plurality of fasteners, and a plurality of positioning holes to receive the corresponding positioning rods.
