Sealing system for high pressure converter - uses sliding ring seal and releasable locking piece

摘要

The pressure converter is for prodn. of very high pressures. It has a sealing system in the high pressure region with a sliding ring seal (12) which seals the high pressure cylinder cavity (15) and is held under tension by a spring device (14) using a bush (11) arranged in the cylinder bore of the high pressure cylinder. The spring device is mounted on a releasable locking piece (6) and sealing on the locking piece side is accomplished by a metal conical seal (21, 22). USE/ADVANTAGE - Reliable seal in high pressure region of pressure converter even with large dia. high pressure piston.
