The invention provides a liquid spray gun connectable to a fluid reservoir through a fluid outlet. The spray gun comprises a socket geometry arranged for engagement with a co-operating connector for releasable connecting the spray gun with the fluid outlet. The socket geometry comprises a bore having an opening on one end, an end surface surrounding the bore's opening at least partially, and a lug portion spaced apart from the end surface in an axial direction parallel to a central axis of the bore. The lug portion has a lower surface being adapted to engage with the connector and to retain the connector in the axial direction. The end surface comprises a first keying geometry that is adapted to restrict rotation of the connector in at least one direction.

Liquid spray gun, connector ring, liquid spraying apparatus and adapter system

A liquid spray gun nozzle assembly is disclosed comprising a coating liquid inlet portion comprising a liquid connector for connection to an external liquid source; a coating liquid outlet portion comprising a liquid nozzle for spraying a coating liquid fed into the nozzle assembly through the coating liquid inlet portion, the liquid nozzle being disposed along a spray axis; a coating liquid flow path fluidly connecting the coating liquid inlet portion to the liquid nozzle; and a spray gun connection portion opposite the coating liquid outlet portion adapted to connect the liquid spray gun nozzle assembly to a compatible liquid spray gun body. The spray gun connection portion comprises a nozzle assembly sealing surface adapted to seal the liquid spray gun nozzle assembly to the compatible liquid spray gun body, the nozzle assembly sealing surface comprising first and second sealing members that are each circular and concentric with one another.

Spray gun and nozzle assembly attachment

Spray gun reservoir components are disclosed. The spray gun reservoir component includes a liquid outlet and an outer face, and defines a centerline plane and an attachment plane. The liquid outlet surrounds a longitudinal axis. The outer face extends away from the liquid outlet. The centerline plane passes through the longitudinal axis. The attachment plane is defined orthogonally to the longitudinal axis and the centerline plane. The outer face further comprises a retention feature extending away from the centerline plane and generally parallel to the attachment plane. In some embodiments, the spray gun reservoir component further comprises a bearing surface formed on the outer face along the attachment plane to engage with a corresponding bearing surface on a liquid spray gun attachment point, with the bearing surface comprising the retention feature.

Connector system for hand-held spray guns

A reservoir system for use with a spray gun. The system includes a cup receptacle and a lid. The lid includes a lid body and a collar. The lid body provides a spout and a platform surrounding the spout. At least a portion of the platform forms a partial helical shape revolving about a central axis of the spout. The collar is rotatably connected to the lid body. Further, the collar includes a lid connector structure configured to connect the lid to the cup receptacle. In some embodiments, the reservoir system further includes one or more of an adaptor, a plug and a shaker core.

Reservoir systems for hand-held spray guns and methods of use

A spray gun reservoir connector system. The system includes a reservoir lid, a spray gun inlet, and complementary first and second connector formats. The first and second connector formats are provided with one of either the lid or the spray gun inlet. The first format includes a plurality of retention structures each defining a capture region. The retention structures are collectively arranged in a circular pattern. The second format includes a plurality of lock structures each including a shim body configured to selectively interface with the capture regions. The connector formats are configured to provide wedged engagement between the lock structures and corresponding ones of the retention structures upon rotation of the spray gun inlet relative to the lid. The lid may include a spout. The retention and lock structures are radially spaced outside of the spout, and the spout may have an inner diameter of not less than 22 mm.
