ABSTRACT:
The object of the invention is to provide a self-contained spray applicator for one handed operation in a zero gravity vacuum environment by a free-flying astronaut not attached to any spacecraft while avoiding contamination of the operator by back spray.
Said applicator includes a rigid accumulator (12) for containment of a fluid (17) within a flexible bladder (16), the fluid being urged out of the accumulator under pressure through a spray gun (13). The spray gun includes a spring loaded lockable trigger (47) which controls a valve (56). When in an open position, the fluid passes through the valve into the ambient environment in the form of a spray. A spray shield (14) is provided which directs the flow of the spray from the applicator by trapping errant particles of spray yet allowing the passage of escaping gases through its material. This reduces the reactive force exerted by the escaping spray on the operator of the applicator. The spray shield consists of two concentric layers of open celled urethane foam with the inner layer consisting of a coarser grain than the outer, thereby trapping progressively finer particles of spray.
