Abstract: Vent assemblies movable between a vented position and a non-vented position are described along with reservoirs in which the vent assemblies may be used. The vent assemblies each include an aperture and a closure member. The closure member is configured for movement along a cam surface to generate a compressive force such that a sealing surface on the closure member is forced against the wall of the reservoir and over the aperture such that the vent assembly is in the non-vented position. The closure member movement may be, e.g., rotational or linear (i.e., translational) when moving between the vented and unvented positions.
Abstract translation: 在排气位置和非排气位置之间移动的通风组件与其中可以使用排气组件的容器一起被描述。 排气组件各自包括孔和封闭构件。 闭合构件构造成沿着凸轮表面移动以产生压缩力，使得封闭构件上的密封表面被迫抵靠储存器的壁并且在孔上方，使得排气口组件处于非排气位置。 当在排气位置和未排放位置之间移动时，关闭构件运动可以是例如旋转的或线性的（即平移的）。

Abstract: A liquid spray gun nozzle assembly is disclosed, featuring a coating liquid inlet portion with a liquid connector for connection to an external liquid source, and a coating liquid outlet portion with a liquid nozzle for spraying the coating liquid along a spray axis. The assembly includes a coating liquid flow path connecting the inlet portion to the liquid nozzle. Opposite the outlet portion, a spray gun connection portion is designed to connect the nozzle assembly to a compatible spray gun body. This connection portion includes a nozzle alignment feature that aligns with a corresponding feature on the spray gun body.

Abstract: A liquid spray gun nozzle assembly is disclosed comprising a coating liquid inlet portion and a coating liquid outlet portion, and a coating liquid flow path connecting the coating liquid inlet with the coating liquid outlet. The spray gun connection portion opposite the coating liquid outlet portion is adapted to connect the liquid spray gun nozzle assembly to a compatible liquid spray gun body. The spray gun connection portion includes a liquid sealing member configured to facilitate provision of a liquid needle within a liquid needle zone and an air sealing member configured to isolate an air zone. The air sealing member includes a tapering rim. The liquid sealing member and the air sealing member are circular in shape.

Abstract: Provided are nozzle assemblies for a spraying apparatus having an outer wall (146) having opposed inner and outer surfaces, a central aperture (136) extending through the outer wall, and a pair of auxiliary apertures (158) disposed on the outer wall (146). Each auxiliary aperture is aligned along a respective auxiliary axis (162) and areas of the inner surface (164) of the outer wall (146) adjacent to the auxiliary apertures (158) are countersunk to define ledges (166) that are axially symmetric about the auxiliary axes (162). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.
