The Sealing System

A stainless steel piston anclosed by two resiliend valve ring forms the sealing system.The sealing sealing area is the surface of the piston. The upper valve ring ensures thinkhtness against the atmosphere, while the lower valve ring provides sealing across toports. Belleville washers, compansetes the diferences in the tempature and pressure, so that it ensure permanent sealing whith atomatic maintenance. Kx-gt rings contains lamelles of graphite and tang metal stainless steelshets.
