An electronic cigarette and an atomizer device thereof are provided. The atomizer device includes a housing, a liquid reservoir chamber (115) formed in the housing, and a adjusting valve (13) engaging with the housing; a liquid injection channel (1131) is defined in the housing for injecting liquid solution into the liquid reservoir chamber (115); a first opening (1311) corresponding to the liquid injection channel (1131) is defined in the adjusting valve (13); the adjusting valve (13) is movable between a first position and a second position across a surface of the housing; when the adjusting valve is in the first position, the first opening (1311) communicates with the liquid injection channel (1131) to open the liquid injection channel (1131), and when the adjusting valve (13) is in the second position, the first opening (1311) misaligns with the liquid injection channel (1131) to close the liquid injection channel (1131).

A valve (1), in particular a vacuum valve, having at least one valve housing (2), at least one closure element (3), and at least one valve seat (4). The valve seat (4) surrounds at least one valve opening (5) of the valve (1), and the closure element (3) can be moved back and forth between at least one open position, in which the closure element (3) at least partly releases the valve opening (5), and a closed position, in which a sealing surface (8) of the closure element (3) is pressed against the valve seat (4) in order to close the valve opening (5), by at least one closure element drive (6, 7). At least one surface (9) of the valve (1) has an average surface roughness RZ less than or equal to 0.4 um, preferably less than or equal to 0.25 um.

A valve device is provided with a valve body driving member rotated by driving force from a drive source, and a valve body rotating in a circumferential direction integrally with the valve body driving member. Fitting parts fitted one another are formed in the lower surface of the valve body driving member and the upper surface of the valve body. The valve body has hole parts formed therethrough in the axial direction thereof. Groove parts that are flow channels linking from the outer peripheral surface of the valve body to the hole parts are formed in the upper surface of the valve body. The fitting parts and the groove parts on the valve body side have connecting parts that are portions where the fitting parts and the groove parts are formed continuously in the upper surface of the valve body without being separated by other elements constituting the valve body.

A valve comprises: a housing defining a chamber; a fluid outlet defined by a fluid outlet wall; and a first fluid outlet orifice and a second fluid outlet orifice comprising a rigid seat. The valve comprises a movable gate, that is flexible and/or compressible and impermeable. The moveable gate is more flexible than the rigid seat, has a planar surface, and is configured to slidably move in a first axis. The movable gate is configured to be positioned so that it is located between a fluid inlet orifice and the second fluid outlet orifice when the valve is in a closed position, wherein fluid pressure within the chamber causes the movable gate to seal the second fluid outlet orifice via the rigid seat, and not the fluid inlet orifice. The valve may employ gate shapes that generate and/or exploit Bernoulli effect forces when fluid passes though the valve.

A toilet bowl system for use on-board an aircraft includes a toilet bowl body comprising a toilet bowl and a shroud. The toilet bowl has a rim. A removable splash guard is positioned between the toilet bowl and the shroud, and comprises a generally flat, flexible, planar shield having a central opening. The shield includes a top portion and a rear portion, the top portion faces the shroud and the lower portion faces the toilet bowl, and the lower portion is shaped to correspond with an upper portion of the rim of the toilet bowl and is configured to secure the removable toilet splash guard to the toilet bowl.

Valve cartridges for a faucet are described herein. The valve cartridge has a body with a longitudinal passage, and a side opening. The cartridge has a spindle with a lower end portion in rotatable relationship with the body's interior surface, and an upper outwardly extending end portion. Included is a movable disk with a surface that contacts and interacts with the lower end portion of the spindle, an arcuate side wall portion and an inwardly extending side wall portion with a fluid receiving area that allows for fluid flow out of the body side opening. A stationary disk with a through opening allows passage of fluid from a body inlet through the side opening when the opening in the disk is aligned with the fluid receiving area. A sealing ring, which mates with the body, is provided to stabilize the stationary and movable disks within the body passage.
