Abstract
The pressure reducing regulator includes a regulator body with a tubular portion coaxially aligned with the tubular portion of a bonnet threaded to the regulator body. A piston has a bore extending therethrough with the tubular portions extended thereinto in axial spaced relationship, the body tubular portion mounting a valve seat to abut against a piston internal shoulder when the piston has axially moved relative to the tubular portions to a blocking position to block fluid flow through the regulator. The piston enlarged diametric portion bottom surface is in fluid communication with the piston bore in both of the piston positions but not in fluid communication with the body high pressure inlet when the piston is in its blocking position. A spring resiliently retains the piston in its open position when no pressurized fluid is applied to the body inlet.
