Abstract:
A coupling assembly (56) for coupling an exhaust system to a pipe through which hot gases are discharged. The coupling assembly (56) couples the exhaust pipe (54) of a vehicle (16) to a flexible exhaust suction hose (42) of a vehicle emission capture system (10) of the type that discharges vehicle exhaust gases from within a structure (12) to a location outside of the structure. The coupling assembly includes two portions, one portion being a rubber-like boot (62) which is secured to the free end (42. 3) of a flexible suction hose (42), the rubber-like boot carrying near its free end (62. 2) a garter spring (64), and the other portion of the coupling assembly being a ball adaptor (60) which may be secured to the tail pipe (54) of a vehicle. The ball adaptor has a connection portion (60. 1) and a spherical portion (60.
