Problems solved by technology

However, these types of liquid supply assemblies should only be used with the top of the container substantially up, because if the container is tilted far from this position, the liquid column feeding the spray gun will be compromised and liquid may enter the Air supply lines that cause line blockages and / or flow through the line into the gun section where they can cause working or cleaning problems

Embodiment Construction

[0017] see now figure 1 and 2 , shows a liquid supply assembly according to the present invention, which is generally indicated by reference numeral 10 . Such as figure 1 As shown, the liquid supply assembly 10 can be used to supply the liquid to be sprayed to a conventional gravity-fed liquid spraying device or spray gun 11, such as the illustrated spray gun 11, which is commercially known as "SATA" (t.m.) NR -95" and are available from Sata, Farbspritzenchnik Gmbh & Co., Kornwestheim, Germany.

[0018] The liquid supply assembly 10 includes a container 12 made of a rigid polymeric material that appears transparent, such as injection molded clear clear polypropylene to have walls about 0.047 inches or 1.2 millimeters thick. The container 12 includes a generally cylindrical side wall 13 having top and bottom ends 14 and 15 , and a bottom wall 16 extending across the bottom end 15 of the side wall 13 . The bottom wall 16 has a central circular opening 17 around which an ann...

Abstract

An assembly (10) for feeding liquid to the inlet of a liquid spraying device or spray gun (11). The assembly includes a rigid container (12) and a flexible liner (20) positioned within a cavity in the container (12), the liner having an outer surface generally conforming in shape to the inner surface of the container and an annular lip along the top of the side wall and forming an opening into the cavity of the bushing (20). An air supply assembly (90) connected to the container (12) supplies air at a relatively low pressure between the outer surface of the flexible liner (20) and the inner surface of the container (12), which improves flow through the container (12). The assembly is attached to a spray device or spray gun for fluid flow and enables use of the spray device or spray gun in any orientation (11).

Description

technical field [0001] The present invention relates to a liquid supply assembly for supplying a liquid to be sprayed (e.g., paint) to a liquid spraying device such as a spray gun, and in one aspect, to such a device for supplying liquid from a collapsible bushing to a liquid spraying device or spray gun. A liquid supply assembly. Background technique [0002] Various gravity-feed liquid supply assemblies have been used to supply liquid to be sprayed to liquid (e.g. paint) spraying devices such as spray guns, including International Publication No. WO 98 / 32539 of July 30, 1998. A collapsible liner liquid supply assembly as described in (Joesph). The liquid supply assembly described in WO 98 / 32539 comprises a container of rigid polymeric material comprising a generally cylindrical side wall and a bottom wall at the bottom end of the side wall, And the opposite top end of the side wall forms an opening to the cavity of the container, and a flexible liner is arranged in the c...
