Abstract
An assembly 10 which includes primary and secondary hydrocarbon material reception and storage devices 22, 24 in a cascaded and communicative relationship. Particularly, the device 24 receives and stores hydrocarbon emissions 20 which emanate from the device 22. Device 24 further includes a filter 50 through which purging air is communicated to the devices 22, 24. Further, device 24 includes a condensation removal portion 52 which allows condensation 92 to be vented from the device 24 and a selectively closeable vent portion 54 which allows the device 24 and the assembly 10 to be periodically tested.
Claims2
An assembly for minimizing hydrocarbon emissions from a motor vehicle having an internal combustion engine and a fuel tank, comprising:
- a first canister device for receiving hydrocarbon emissions emanating from the fuel tank;
- and
- a second canister device, coupled to said first device, for receiving hydrocarbon emissions emanating from the first device, with said second device comprising:
- a generally hollow body for absorbing hydrocarbon emissions emanating from the first device;
- an air filter, coupled to said generally hollow body, for minimizing the amount of particulates entering the first device;
- a drain for allowing condensation to be vented from said assembly;
- and
- a convoluted slide in communication with said drain.
