REFRIGERATED CONTAINER DUCT COUPLING

摘要

The connecting seal fits over the sleeve (22). the container wall (14) has a hole (16) in line with the air passage. the sealing ring (36), is moved by the compressed air bag (30) being inflated. the compressed air is also supplied to the cylinder (38) through the connecting tubes (44, 46). the cylinder presses against the wall of the container and forms a seal for the inlet. The sealing ring (36) is returned to its starting position when the compressed air is released by an elastic cord (52) fixed to the ouside well (10) and to the ring.
