Assembly of a gate valve and a seal system for sealing the gate valve of a thermal engine

摘要

The arrangement (1) has a seal system (3) sealing a slide valve (2). A solid lubricant is provided between the valve and the system. The system temporarily seals a working chamber and/or lines of a heat engine. A solid lubricant rubbing body (4) is provided independent of the system. The body contacts a sliding seal surface (8) of a tribological system of the valve and the seal system. The body transfers the lubricant onto the surface and another seal surface (9) of a sliding sealing ring (6) by abrasion when moving relative to the surfaces. The lubricant partially lubricates the surfaces. The solid lubricant is based on carbon and/or plastic. The solid lubricant rubbing body is designed as a strip-like, cylindrical or box-shaped profile.
