Connecting coupling for filling devices for transfer of fluids from supply tank to receiving tank has sealing sleeve with locking device movable in entry direction of delivery connection by gas pressurized chamber

摘要

The connecting coupling for filling devices has a sealing sleeve (5) with a locking device (6) movable in the entry direction of a delivery connection (2) against a compression spring (11) in the coupling housing by a gas pressurized chamber (10). For coupling and decoupling through the displaced sealing sleeve, circumferentially distributed locking rollers (12) in the coupling section are released, and with the delivery connection inserted after compressed gas shutoff by the compression spring a locked position is set with the locking rollers engaging in the threaded portion of the delivery connection.
