A device for mechanically, automatically, and sequentially switching the flow of fluid from a pressurized source between two fluid outlets, which comprises: a body defining an interior cylindrical barrel having a circular cross-section; first piston means disposed in said barrel towards one end thereof, said piston means being capable of rotational and axial motion within said barrel in response to axial force exerted on said piston means; second piston means, disposed in said barrel toward the other end thereof at a position distal with respect to said first piston means to define an enclosed cylindrical volume within said barrel between said piston means, said second piston means also being capable of rotational and axial motion within said barrel in response to axial force exerted on said piston; first conduit means capable of connecting said device to said pressurized source of fluid, said conduit means establishing fluid communication with said cylindrical volume within said barrel between said pistons; first and second output conduits, establishing fluid communication with the interior of said barrel, respectively, in the regions of said barrel capable of being traversed by said first and second piston means; energy storage means coupled to said first and second piston means, for extracting energy from said pressurized source of fluid and releasing said energy to move said piston means toward said central volume, whereby said piston means may be forced apart when said source of pressurized fluid is turned on to exert pressure against said pistons, and forced together when said source of pressurized fluid is turned off by release of stored energy from said energy storage means coupled to said piston; and guide means for alternately permitting one of said pistons to open one of said output conduits to selectively establish fluid communication between said output conduit and said central volume.
