A raw material supply apparatus includes: a raw material supply path through which a raw material gas is supplied into a processing container; a valve provided in the raw material supply path; a pressure sensor configured to detect an internal pressure of the raw material supply path; a raw material exhaust path connected to the raw material supply path and through which the raw material gas in the raw material supply path is exhausted; an opening degree adjustment mechanism provided in the raw material exhaust path and configured to control the internal pressure of the raw material supply path based on an adjustment of an opening degree of the opening degree adjustment mechanism; and a controller configured to perform the adjustment of the opening degree of the opening degree adjustment mechanism based on a value detected by the pressure sensor.

An intermittent air blow gun (10a) has a switching valve (26) including a switching-valve case (27) and a valve assembly (31), and the valve assembly (31) includes: a valve body (53) configured to open and close a valve hole; a small-diameter piston (33) partitioning so as to form a small-diameter pilot chamber (34); and a large-diameter piston (37) partitioning so as to form a large-diameter pilot chamber (38). The valve body (53) is switched to a closed position when air discharged from an inside of the switching-valve case (27) to an air discharge section (24) is supplied to the large-diameter pilot chamber (38) through a bypass flow path (77), and the valve body (53) is switched to an open position when air is exhausted.

A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining a fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and a piercing member for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the piercing member is arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

A flow regulation device for liquid having a body with an inlet opening, an outlet opening, and a cavity between the two openings. An actuating means is disposed in the cavity for stopping and starting the flow of liquid through said device. The actuating means is configured to be moved in a first direction to start the flow of liquid through said device and in the first direction to stop the flow of liquid through said device. The actuating may comprise an upper button and a lower cam.

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 modular faucet system for an aircraft comprising a faucet outlet, a flow valve, and an actuator. The faucet outlet is configured to be installed on the aircraft. The flow valve is configured to be installed on the aircraft separately from the faucet outlet, to be connected by a first water line to a water supply comprising a water tank on the aircraft, and to be connected by a second water line to the faucet outlet. The actuator is configured to be installed on the aircraft separately from the faucet outlet and the flow valve. The actuator comprises a touchless sensor that is configured to detect a user of the modular faucet system. The actuator is configured to generate a control signal to open the flow valve to provide water from the water supply to the faucet outlet in response to detection of the user by the touchless sensor.
