The present invention relates to the field of non-electric multi-channel valves adapted to provide specific flow patterns to aqueous liquids, vapor or gas, and, more particularly, to non-electric multi-channel valves configured to provide continuous outflow to aqueous liquids, vapor or gas.

A water control system including a showerhead and a tub faucet. The faucet has a valve configured to automatically restrict fluid flow through the faucet and direct fluid to the showerhead as a function of a parameter, such as a predetermined water temperature. The faucet has many modes of operation, including a Reset Mode, an Auto-Divert Mode, a Bypass Mode, and a Cold Mode. A flow control device generates minimal back-pressure when in the Reset Mode such that water does not undesirably back flow to a shower head.

A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a first liquid vapor discriminator (LVD), a main housing, a first poppet valve assembly, a pump and an actuator assembly. The first LVD is disposed in the fuel tank. The main housing selectively vents to a carbon canister. The first poppet valve assembly has a first poppet valve arranged in the main housing. The pump selectively pumps liquid fuel from the main housing. The actuator assembly is at least partially housed in the main housing and includes a cam assembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that one of opens and closes the first poppet valve fluidly coupled to the first LVD.

A water control device that can be introduced into the main water supply line for a structure configured for automatic direct water allocation has a manifold with an inlet port and an outlet port in fluid communication with one another and a quarter turn valve disposed between the inlet and outlet ports and in fluid communication therewith. The quarter turn valve has a truncated conical shaped valve body that fits within a well in the manifold, the valve body having spaced apart solid side walls which define openings within opposite side walls, such that rotation of the valve body by a quarter turn will align either an opening or a solid side wall with the inlet and outlets ports for the well, thus alternately permitting or disrupting the flow of water through the valve. The valve body further includes a plurality of spaced apart cam projections on a bottom surface thereof, the cam projections cooperating with a plurality of spaced apart cam projections disposed on a bottom surface of the well such that the valve body undergoes vertical displacement as it rotates.

Disclosed is a water softener valve and a water softener, the water softener valve includes a valve body, the valve body includes a valve cavity, and an inlet passage, an outlet passage, and a waste water passage all communicated with the valve cavity, the valve cavity, the inlet passage, the outlet passage, and the waste water passage all extend towards a first direction, the inlet passage, the outlet passage, and the waste water passage are all located at a periphery of the valve cavity, and adjacent to the valve cavity; ends of the inlet passage, the outlet passage, and the waste water passage which are all located at a same end of the valve body towards the first direction respectively form an inlet, an outlet, and a waste water port.

A medical push button valve having a valve housing, a flow channel formed in the valve housing as well as a valve piston which is arranged displaceably in the valve housing between a position releasing the flow channel and a position closing the flow channel. The valve piston is operatively connected with a pressure element mounted on the valve housing and is spring-loaded via at least one spring element. The valve piston is biased into the position closing the flow channel with the spring-loaded pressure element. In order to provide a medical push button valve which allows for a simple and fatigue-free one-handed operation, the spring-loaded pressure element can be locked in at least one position in which the valve piston operatively connected with the pressure element at least partially releases the flow channel.

A water control system including a showerhead and a tub faucet. The faucet has a valve configured to automatically restrict fluid flow through the faucet and direct fluid to the showerhead as a function of a parameter, such as a predetermined water temperature. The faucet has many modes of operation, including a Reset Mode, an Auto-Divert Mode, a Bypass Mode, and a Cold Mode. A flow control device generates minimal back-pressure when in the Reset Mode such that water does not undesirably back flow to a shower head.

A linear drive apparatus including: a housing. Located inside the housing are an electric motor, a transmission gear, which meshes with an output gear on an output shaft of the electric motor, a gear shaft, and a linear motion assembly. The transmission gear is mounted on the gear shaft, the linear motion assembly is mounted to cooperate with the transmission gear, and converts rotational motion of the transmission gear to linear motion. An axis of the linear motion assembly is arranged in the same plane as an axis of the electric motor output shaft and an axis of the gear shaft. The linear drive apparatus has the advantages of a compact structure, small volume, light weight, and good heat dissipation.

A control system for a coolant control valve unit, which includes a cam and a valve that opens and closes a coolant passage in conjunction with rotation of the cam, includes: a motor controlling the rotation of the cam; and a controller configured to correct a target valve opening degree of the valve using a correction value according to a degree of wear of the valve, to determine a target rotational angle of the cam using the target valve opening degree corrected by the correction value, and to control an operation of the motor according to the target rotational angle of the cam.

A coolant control valve unit is provided. The valve unit includes a valve that opens and closes a coolant path and a rod that is extended from one side of the valve. A cam is also provided which includes a track formed with a predetermined inclination and a predetermined height along a rotation direction with respect to a rotation axis. The track thus presses the rod according to the rotation of the cam which is rotated about the rotation axis by and an actuator.
