This invention shows a type of dual-sensing basin faucet, includes the shell of faucet, the shell of this faucet is setting a valve seat with adjustment switch. The top of valve seat is connected to the cavity of water outlet and cavity of solenoid valve. There is the outlet tube inside the cavity of water outlet and a solenoid valve inside the cavity of solenoid valve. Both outlet tube and solenoid valve are setting inside the shell of this faucet. There is circuit board setting on the top of outlet tube, and the circuit board is electrically connected with the solenoid valve. There is a support plate that is setting above the circuit board and is firmly connected with the circuit board.

A switched nozzle valve (SNV) for gas flow regulation includes a nozzle and a valve element. The nozzle includes an orifice with a fixed cross-section and a converging section converging towards the orifice for achieving sonic velocity of the gas in the orifice. The valve element is movable between a fully closed position seated on the nozzle at a valve seat and a fully open position spaced from the valve seat. The SNV further includes a control for controlling an operator for switching the valve element between the fully open and fully closed positions at a switching frequency by using a pulse-width-modulation (PWM) signal to regulate a time-averaged flow of the gas.

A fluid transfer device can include a first attachment portion configured to engage a first port of a source container and a second attachment portion configured to engage a second port of an intermediate container. The first attachment portion can include a first projection defining a first fluid passage and the second attachment portion can include a second projection defining a second fluid passage. The fluid transfer device can further include a selector portion for selectively transitioning the fluid transfer device from a first configuration in which a flow path between the first and second fluid passages is closed to a second configuration in which the flow path between the first and second fluid passages is open. The fluid transfer device can further include a limiter configured to inhibit the selector portion from selectively transitioning the fluid transfer device from the first configuration to the second configuration.

A fluid distribution system can include a water inlet configured to receive water from a supply spout. A supply line can be connected to the inlet, and an applicator tip can be connected to the supply line distal from the inlet. The applicator tip can be configured to spray water received through the supply line at the same time as the receiving of the water from the supply spout through the inlet. The system can further include a water pressurizing device that is operable to pressurize water received from the supply spout via the water inlet and supplied through the supply line to the applicator tip. The water pressurizing device can include one or more of a powered fluid pump and a source adapter. The system may include a fluid-actuated pressure clamp.

A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

An on-off valve includes a valve body housed in a valve body housing portion provided in a main body, the valve body being switchable between an open position and a closed position, an operating means that switch the valve body between the open position and the closed position, a discharge channel, one end of the discharge channel being communicated with a valve chamber of the main body, another end of the discharge channel being communicated with a discharge port, an attaching member inserted into the main body and protruding to a container side of the main body, and including a connection portion at a distal end of the attaching member, the connection portion being connected to a container discharge portion, and an insertion portion provided in the main body, the attaching member rotatably penetrating through the insertion portion, the insertion portion being communicated with the valve body housing portion.
