Patent ID: 7143960

Claim:
A fluid reservoir for a spray gun, the reservoir comprising a syringe body having a first, substantially closed end and a second, open end, the open end being connectable, in use, to a spray gun, and a plunger having a sealing member resident in the body and a shank passing through an opening in the first end operable to create at least a partial vacuum within the body for drawing fluid into the reservoir via the open end when disconnected from the spray gun, characterised in that means is provided for controlling the at least partial vacuum, wherein the means for controlling the at least partial vacuum comprises an aperture through a wall of the body proximate the first end of the body such that, in use, the scaling member can be moved away from the second, open end to a first position between the second, open end and the aperture to draw fluid into the reservoir, and to a second position between the aperture and the first, closed end to allow fluid to be withdrawn from the reservoir via the second, open end whereby, when the oven end of the reservoir is connected to the spray gun, fluid can be withdrawn from the reservoir via the open end for supply to the spray gun independently of an actuation force applied to the plunger externally of the reservoir.
