ABSTRACT:
In accordance with the present invention, there is provided a self-actuating fluid dispenser change-over device for selectively dispensing a fluid from multiple fluid sources. The change-over device is provided with a housing having first and second cylinders. The change-over device is further provided with first and second pistons which are interconnected and movable between open and closed positions within respective ones of the first and second cylinders. The change-over device is further provided with a slide valve which is movable between first and second positions for alternately dispensing fluid from a respective one of the first and second cylinders. The change over device is further provided with a linkage which connects the pistons to the slide valve for moving the slide valve in response to movement of the pistons. The linkage has a biasing spring for urging the slide valve between a respective one of the first and second positions. The change-over device configured such that when first piston is in the open position, the second piston is in the closed position and when the second piston is in the open, position the first piston is in the closed position. The pistons move in response to a fluidic pressure differential between the first and second cylinders which is sufficiently large so as to cause flexure of the biasing spring thereby facilitating movement of the slide valve between the first and second positions.
