Check valves; tubular valves; shocks, preventing; closing, retarding.-An automatic check valve B, guided above and below as shown, is fitted with or made in one with a piston C sliding freely in a cylindrical chamber D and serving to close the exit port K just before the valve B reaches its seat, whereby the closing of the valve B is retarded and hammering is prevented. Apertures L connected by a groove M prevent fluid from becoming impounded in the space above the valve. The piston C may have a brass shell E.
