Abstract: Valve structure for reversing gas flow comprising a housing containing a pair of disposed cylinder chambers, a pair of disposed manifold chambers, inlet and outlet means provided in each pair of said cylinder and manifold chambers, piston means provided in each cylinder chamber positioned therein to selectively effect flow between inlet means in said manifold chamber and outlet means in said cylinder chamber and flow between inlet means in said cylinder chamber and outlet means in said manifold chamber, said pistons slideably arranged in said cylinder chambers and fixedly mounted on piston rods, said rods extending slideably through the walls of the manifold chamber, and driving means connected to said piston rods for inducing said rods to reciprocate thereby effecting sliding motion of the pistons within said cylinder chambers and thereby reverse the flow between the inlet and outlet means in said cylinder chambers.
