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.

A valve for use in filling containers includes a valve flange, nozzle assembly and valve sleeve. The valve flange defines a first through passage. The nozzle assembly includes a nozzle head having a liquid fill outlet and air vent outlet below the valve flange and leading to a vent tube. The valve sleeve defines a second through passage and is movable between a lowered valve closed position and a raised valve open position. The valve sleeve including a first portion positioned for sliding movement within the first through passage and a second portion positioned below the valve flange and configured for sealingly closing both the liquid fill outlet and the air vent outlet when the valve sleeve is in the lowered valve closed position. The nozzle head is formed of a non-metal material. A valve may also be mated to the vent tube by a captive retaining clip.

A valve body for a servovalve is provided comprising: a first surface adapted to extend parallel and adjacent to a substantially flat pole piece surface of a pole piece in use; and attachment features provided on the first surface for attaching the valve body to the pole piece in use, wherein the first surface is contoured such that, in use, an area of the first surface surrounding the attachment features is in contact with the substantially flat pole piece surface and an area of the first surface removed from the attachment features is not in contact with the substantially flat pole piece surface.

A self-acting pressure activated drain valve includes at least one inlet configured to receive a fluid. A drainage passage delivers the fluid to at least one outlet where the fluid is expelled. The self-acting pressure activated drain valve further includes a flexible diaphragm configured to operate in an open position and a closed position based on a pressure. The flexible diaphragm is normally biased in the open position such that fluid is delivered from the at least one inlet to the at least one outlet via the drainage passage. The pressure, however, initiates the closed position such that air is prevented from flowing through the drainage passage.

A purge device includes: a plurality of mounts on which containers are to be placed and that are grouped, a nozzle that is structured such that when a container is placed on the corresponding mount, a flow path to supply a purge gas to the container is opened, and a flow rate controller that adjusts a flow rate of the purge gas supplied into a group based on a number of containers in the group.

A drive transmission device includes a drive source, a first drive transmitter and a second drive transmitter. The drive source generates a drive force. The second drive transmitter is coaxially arranged with the first drive transmitter and includes a material different from a material of the first drive transmitter. The drive force of the drive source is transmitted between the first drive transmitter and the second drive transmitter. The first drive transmitter is fastened to the second drive transmitter.
