Abstract
A vehicle exhaust evacuation system includes an adapter secured to an end of a vehicle tailpipe and a nozzle assembly secured to the end of a flexible hose for carrying vehicle exhaust outside of a building. The nozzle assembly has an aluminum cartridge removably secured in a rubber boot. Magnet assemblies are secured to the aluminum cartridge. Openings in the adapter allow ambient air to flow over the magnet assemblies to lengthen the life of the magnets.
Claims20
A vehicle exhaust evacuation system comprising:
- an adapter for securement to a vehicle tailpipe and a nozzle assembly for securement to a flexible hose,
- said adapter comprising a generally cylindrical fitting adapted to surround the vehicle tailpipe and a contact plate secured to the generally cylindrical fitting and extending radially outwardly from generally cylindrical fitting,
- said nozzle assembly having reducer at a downstream end of the nozzle assembly, a rubber boot at an upstream end of the nozzle assembly and an elbow between the reducer and the rubber boot,
- an aluminum cartridge secured inside a hollow interior of the rubber boot, said aluminum cartridge having a central opening and cooling passages extending through the aluminum cartridge,
- magnet assemblies secured inside receptacles extending through the aluminum cartridge,
- an inner sleeve extending through the central opening of the aluminum cartridge, said inner sleeve having a flange portion extending radially outwardly from the body portion of the inner sleeve, the body portion of the inner sleeve extending upstream of the aluminum cartridge and being coaxial with the rubber boot,
- a silicone gasket sandwiched between the flange portion of the inner sleeve and the aluminum cartridge, wherein the contact plate of the adapter abuts the aluminum cartridge of the nozzle assembly due to the magnet assemblies.

A vehicle exhaust evacuation system comprising:
- an adapter for securement to a vehicle tailpipe and a nozzle assembly for securement to a flexible hose,
- said adapter comprising a generally cylindrical fitting adapted to surround the vehicle tailpipe and allow exhaust from the vehicle to pass through the adapter and into said nozzle assembly, said adapter having a contact plate to which magnet assemblies of the nozzle assembly are drawn,
- said nozzle assembly having a reducer at an upstream end of the nozzle assembly, a rubber boot at a downstream end of the nozzle assembly and an elbow between the reducer and the rubber boot,
- a cartridge secured inside a hollow interior of the rubber boot, said cartridge having a central opening,
- said magnet assemblies of the nozzle assembly being secured to the cartridge,
- an inner sleeve extending through the central opening of the cartridge, said inner sleeve having a body portion and at least one flange portion, the body portion of the inner sleeve extending through the central opening of the cartridge and being coaxial with the rubber boot,
- a silicone gasket sandwiched between the at least one flange portion of the inner sleeve and the cartridge.
