Elastomer-free sealing arrangement for a pressure chamber that is connected with a low and high pressure line

摘要

The invention describes a sealing arrangement for a pressure regulator chamber (8) that is connected in an upper part with a low pressure line (14) and in a lower part with a high pressure line (13). For sealing up the high and the low pressure line, a metal sealing element (6,7,23,3) is arranged within the chamber (8) and retained by retaining means (19). For sealing the high pressure line (13) that discharges into a bottom of the chamber (8) a first metallic washer (19) is arranged between a sealing face that surrounds the orifice of the high pressure line and the bottom of the sealing element. The sealing above the low pressure part of the chamber is attained by a washer that (23) is press-fit between the surface of the body (12) in which the chamber (8) is arranged and a further sealing face that is arranged at an upper end of the sealing element. The sealing faces are arranged perpendicularly to a longitudinal axis of the chamber and the sealing element. <IMAGE>
