The invention relates to a suction operated gas evacuating arrangement, particularly for evacuating vehicle exhaust gases, wherein the arrangement includes a suction hose (1) having on a first end (2) thereof a device (3) for connecting the hose to the exhaust pipe of a vehicle (100), and wherein the other end (4) of the hose (1) communicates with a suction channel (5). The arrangement further includes a carriage (40) that can move in the longitudinal direction of the channel (5), wherein the second end (4) of the hose (1) is connected to the carriage (40). The carriage (40) includes means (70) for temporarily lifting a free edge (27) of a seal (24) that extends along the suction channel (5), so as to establish desired communication between the carriage (40) and the channel (5). The seal (24) is orientated so that the weight of the seal will coact in establishing an effective sealing function. |
