Coke oven door

摘要

The door is equipped with hydraulic or compressed-air locking devices, each locking device being assigned a pressure vessel which is closed on all sides and is extensible and compressible in the working direction. Provision is made for the pressure vessel to consist of a corrugated-tube compensator (10) which is closed at both ends by a plate (11, 12), at least one of the two plates (e.g. 12) having a recess (13) for receiving locking components (14). <IMAGE>
