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.

An actuating member is provided. The actuating member acts on a valve core rod. A guide surface is arranged on the actuating member. A guide path is formed on the guide surface. The guide surface is configured to slidably abut against a top end of the valve core rod, so that the top end of the valve core rod selectively abuts against a position on the guide path at a different height, so as to adjust a position of the valve core rod in a valve port of a reversing valve, thereby changing a flow area at the valve port.

A stop assembly includes a top plate and a stem. The top plate is configured to seat onto the stem. The stem is configured to rotate within grooves of the top plate so as to open and close a valve. The stem has a lower surface and an upper surface and includes a mating aperture through the central body extending above the upper surface. It also has a pair of tabs protruding from the upper surface adjacent the mating aperture. The mating surface and the pair of tabs divide the upper surface to form opposing ledges partially around a perimeter of the central body. The top plate has a central aperture and a pair of opposing grooves that create a pair of stops. The stops are configured to rest adjacent the opposing ledges, such that rotation of the stem contacts the pair of stops against the pair of tabs.

An adjustment device for a water delivery unit includes a valve body extending along a longitudinal axis with a water inlet and outlet, a shutter arrangement to control water flow from the inlet to the outlet, a first actuating member movable along the longitudinal axis to arrange shutter arrangement into opening and closing positions to respectively enable/disable the passage of water and a second actuating member rotatable about the longitudinal axis to vary the opening position of the shutter arrangement to adjust a flow rate of the water exiting the valve body. The device has a manual control member coupling with the first and second actuating members and configured to receive a manual action by a user for opening, closing and adjusting the flow rate of the water. The second actuating member cooperates with the shutter arrangement through a cam arrangement for varying the opening position of the shutter arrangement.

A water separator valve assembly is provided, including: a main body, including a chamber, first and second outlet pipe and an inlet pipe; a control assembly, including a valve member disposed in the main body and an elastic plug, the valve member including a base disposed in the chamber and a receiving portion disposed on the base, the base including inlet holes respectively in communication with an inlet channel in the main body, the receiving portion including a receiving hole and a through hole, the elastic plug being disposed in the receiving hole, the elastic plug being elastically abutted between a bottom wall of the receiving hole and an inner wall the chamber; wherein the valve member is rotatable relative to the main body to drive the elastic plug to seal the first outlet channel or an second outlet channel in the main body.

A flow control valve adjusts an opening degree of a second channel by moving a needle valve in a first axis direction in accordance with a rotating operation amount of a knob provided at the first body, and includes a scale body, and a scale reading part that indicates the scale mark corresponding to the rotating operation amount of the knob, and a clutch mechanism that changes the scale mark of the scale body when the knob is rotated. The clutch mechanism includes an engaging portion, an engaged portion, and a clutch drive mechanism, and the scale reading part and the scale body rotate integrally when the engaging portion and the engaged portion are engaged. The clutch drive mechanism releases engagement between the engaging portion and the engaged portion when the knob is rotated and, after the scale mark is changed, re-engages the engaging portion with the engaged portion.

A flow regulating switch valve includes a valve core that includes a switch assembly configured to drive a diaphragm assembly to open or close a water outlet, and also includes a flow regulating assembly that comprises a rotating ring, a sliding block, and a magnet. A control key is configured to control the switch assembly. The rotating ring is connected to the control key and includes an inclined plane that transitions from high to low and is configured to drive the sliding block to slide up and down such that the sliding block drives the magnet to move up and down. The magnet is configured to control the diaphragm assembly to regulate a size of the water outlet.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

A valve (1), in particular a piston valve, including a stationary housing part (2) and an actuating element (3) which can be adjusted relative to the housing part (2) and is in, or can be brought into, an operative connection with a valve body (4). The valve body (4) can be adjusted by way of actuation of the actuating element (3) between an open position which opens an outlet (5) and a closed position which closes the outlet (5). The valve (1) has a damping device (6) for extending a closing time of the valve (1), by an adjusting force which is applied for the closure of the valve (1) being opposed by a damping force which is produced by way of the damping device.

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted to allow the body to move between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section
