A multi-flow valve has an in-let/outlet plate (208) with at least two inlet openings (210, 212) and two outlet openings (214, 216). A fluid flow selector (206) has a fluid passage (228) therein. The fluid flow selector is rotatable with respect to the inlet/outlet plate among a closed position a first open position and a second open position. When in the first open position the fluid flow passage fluidly couples the first inlet to the first outlet and when in the second open position the fluid passage fluidly couples the second inlet to the second outlet. In an aspect, when the fluid flow selector is in the closed position the fluid flow passage fluidly couples the first outlet to the second outlet. In an aspect, the fluid flow passage is an offset arcuate channel.

The application relates to a valve device, including a valve housing which has at least three connection openings, each of which open into a chamber of the valve device, including two sealing disc units arranged at a distance from each other, each of which lies between two adjacent chambers and has a fixed sealing disc and at least one rotatable sealing disc, wherein each of the rotatable sealing discs and the fixed sealing discs of each sealing disc unit has at least one throughflow opening in order, in at least one overlapping position of the throughflow openings, to release a throughflow cross-section between the adjacent chambers, and including an actuating shaft, which is connected to the rotatable sealing discs for conjoint rotation.

A valve cartridge includes a valve body that defines a hot water port that has a first end and a second end. The valve body includes a cold water port that has a first end and a second end. The valve cartridge includes a rotatable control stem that is disposed at least partially within the valve body. The valve body includes a main flow control disc that is coupled to the control stem. The main flow control disc has a cold water opening and a hot water opening. The valve cartridge includes a first auxiliary disc positioned between the first end of the hot water port and the main flow control disc and a second auxiliary disc positioned between the first end of the cold water port and the main flow control disc.

A thermostatic mixer, including manually adjusting means to adjust the inflow rates of hot water and cold water in the mixer, operable by the user, and automatic adjusting means to adjust the temperature of the mixed water delivered by the mixer, adjustable by the user, is described. The user manually adjusts the flow rate and sets the desired temperature of the mixed water; the temperature is feedback controlled by automatic thermostat means. The mixer includes a single control lever operable by the user to control both the manually adjusting means to adjust the inflow rates of hot and cold water and the automatic adjusting means to adjust the temperature of the mixed water. In order to facilitate adjusting of the temperature, the mixer includes a gear mechanism functionally interposed between the control lever and the adjusting shaft of the automatic adjusting means to adjust the temperature of the mixed water.

A valve cartridge includes a valve body that defines a hot water port that has a first end and a second end. The valve body includes a cold water port that has a first end and a second end. The valve cartridge includes a rotatable control stem that is disposed at least partially within the valve body. The valve body includes a main flow control disc that is coupled to the control stem. The main flow control disc has a cold water opening and a hot water opening. The valve cartridge includes a first auxiliary disc positioned between the first end of the hot water port and the main flow control disc and a second auxiliary disc positioned between the first end of the cold water port and the main flow control disc.

A valve includes a main body defining four flow chambers, a first end cap coupled to a first end of the main body, and a second end cap coupled to a second end of the main body. A first rotatable disc is coupled to a rotatable shaft adjacent the first end of the main body and a second rotatable disc is coupled to the rotatable shaft adjacent the second end of the main body. The first rotatable disc includes first and second communication openings and the second rotatable disc includes a third and fourth communication openings. The first communication opening, the first end cap, and the second communication opening cooperate to provide fluid communication between a first pair of the flow chambers while the third communication opening, the second end cap, and the fourth communication opening cooperate to provide fluid communication between a second pair of the flow chambers.

Disclosed is steering drive device for a pressing-controlled valve core, the steering drive device including a fixed top frame, a lifting drive rod, a vertical guide column, a lifting receiving seat, a fork-shaped swinging member, and a steering linkage. The steering linkage has an end that swings laterally when being moved, and the laterally swinging end is provided with a through hole for the fork-shaped swinging member to drive the swing arm, and cause the horizontal post to axially slide. The vertical cross-section of the through hole is rectangular, and the drive horizontal column has a range of up and down movement space in it, so that, when the drive swing arm generates lateral displacement due to vertical swing, it will pull the steering linkage along a circular path laterally moving, and at the same time drives the valve to rotate the actuating seat and cause it rotate laterally.

A valve system includes a handle shell, an airtight seat, an underwater seat, a sealing deformation, a shell, a manual switch and a lower cover. The handle shell may include a touch/induction switch to control the system for adjusting temperature in ceramic valve core with a touch. The system may include two mode of operation, an induction control mode and a manual control mode. The induction control mode may be enabled when a touch/induction switch inlet is coupled to the lower cover and a first water inlet and a second water inlet. The induction controls the opening and closing of the push rod. Further, the manual control mode may be enabled when a manual switch is coupled to the first water inlet and a second water inlet. The manual operation controls the opening and closing of the push rod.

A valve includes a main body defining four flow chambers, a first end cap coupled to a first end of the main body, and a second end cap coupled to a second end of the main body. A first rotatable disc is coupled to a rotatable shaft adjacent the first end of the main body and a second rotatable disc is coupled to the rotatable shaft adjacent the second end of the main body. The first rotatable disc includes first and second communication openings and the second rotatable disc includes a third and fourth communication openings. The first communication opening, the first end cap, and the second communication opening cooperate to provide fluid communication between a first pair of the flow chambers while the third communication opening, the second end cap, and the fourth communication opening cooperate to provide fluid communication between a second pair of the flow chambers.

A valve cartridge includes a valve body that defines a hot water port that has a first end and a second end. The valve body includes a cold water port that has a first end and a second end. The valve cartridge includes a rotatable control stem that is disposed at least partially within the valve body. The valve body includes a main flow control disc that is coupled to the control stem. The main flow control disc has a cold water opening and a hot water opening. The valve cartridge includes a first auxiliary disc positioned between the first end of the hot water port and the main flow control disc and a second auxiliary disc positioned between the first end of the cold water port and the main flow control disc.
