Abstract
An integral fuel cartridge and filter apparatus includes a fuel cartridge, a filter housing coupled to the fuel cartridge, and a filter coupled to the filter housing.
Claims31
An apparatus, comprising:
- a fuel cartridge;
- and
- a filter device coupled to said fuel cartridge, said filter device comprising:
- a filter housing;
- and
- a filter coupled to said filter housing,
- in which said coupled fuel cartridge and filter device are integrated into a single unit, and
- in which said unit is configured to be selectively coupled with or decoupled from a fuel consuming device such that coupling said unit to said fuel consuming device simultaneously couples said fuel cartridge and filter device to said fuel consuming device.
5 more elements
A method of forming an integral fuel cartridge and filter apparatus, comprising:
- providing a fuel cartridge;
- coupling a filter housing to said fuel cartridge;
- and
- coupling a filter to said filter housing,
- in which coupling said filter and filter housing to said fuel cartridge forms a single unit, and
- in which said unit is configured to be selectively coupled to a fuel consuming device such that coupling said unit to said fuel consuming device simultaneously couples said fuel cartridge and filter device to said fuel consuming device.
3 more elements
A method of using a filter, comprising:
- providing a filter;
- coupling said filter to a filter housing;
- and
- coupling said filter housing to a fuel cartridge;
- in which said coupled fuel cartridge and filter housing form a single unit and are configured to be selectively introduced or removed and replaced as a single unit in a fuel consuming device.
2 more elements
An apparatus, comprising:
- container means for containing a supply of fuel;
- coupling means located at a proximal end of said container means configured to selectively couple said container means to a fuel cell system;
- air filter means coupled to said container means,
- in which said coupled container means and air filter means are integrated into a single unit, and
- in which said unit is configured to be selectively coupled to a fuel consuming device such that coupling said unit to said fuel consuming device simultaneously couples said fuel cartridge and filter device to said fuel consuming device.
