Compressed air coupling with axially movable locking sleeve and pressure compensating component is guided in coupling component which on guiding diameter has ball locking groove of increased diameter

摘要

The compressed air coupling with an axially movable locking sleeve (1) and a yoke-form pressure compensating component (2) is guided in a coupling component (3) which on the guiding diameter (14) has a ball locking groove (17) which is increased in the diameter. The coupling component has a seal (13) sliding on the locking sleeve to separate the pressure chamber (6) from the outside air. The coupling component has an external thread and a centering spigot. An independent claim is included for a housing for wall attachment with one or more holes for the mounting of compressed air couplings.
