Abstract: A spring 15 is crimpingly fixed to an element holding plate 14 of the fluid filter. Since the spring 15 is crimpingly fixed to the element holding plate 14, a material having a high elastic limit can be freely selected for the spring 15. At the assembling time, the spring 15 can be prevented from yielding to be elastically deformed, even when the size between the upper end of the element 12 and the crest of the filter case 11 fluctuates. As a result, it is possible to provide a fluid filter which requires no high sizing accuracy of the individual parts composing the fluid filter at the assembling time so that it can be easily assembled.

Abstract: A filter apparatus is connected to an outlet portion of a canister mounted on a fuel supply system for a vehicle. A housing and a filter element are provided. The housing has a connection-opening portion connected to the outlet portion and atmospheric release opening portion communicating with the atmosphere. The filter element includes a frame which surrounds a filter body and is joined over its entire periphery to an inner wall of the housing, dividing an interior of the housing into a clean-side and dirty-side zone. The frame includes only one one-way valve, which allows fluid flow only from the clean-side zone to the dirty-side zone, bypassing the filter element. The filter apparatus is arranged so that fluid entering the housing by the connection-opening portion may pass through the filter element and exit by the atmospheric release opening portion.

Abstract: The object of the present invention is to provide an air filter where the lifetime of the air filter is long and a carbon dust can be efficiently caught with keeping the cost low. The air filter of the present invention comprises a first filter layer 11 impregnated with oil; an oil repellent layer 11a disposed in the downstream side of the first filter layer 11, having the property of repelling the oil; and a second filter layer 12 disposed in the downstream side of the oil repellent layer 11a, impregnated with no oil. The transfer of the oil to the second filter layer 12 is controlled by the oil repellent layer 11a.

Abstract: A fuel supplying apparatus includes a reservoir to be inserted from an opening portion provided in an upper portion of a fuel tank, a tank cover for closing the opening portion of the fuel tank, and a coupling mechanism for coupling the reservoir and the fuel tank with each other so as to be mutually displaceable. The coupling mechanism includes a retainer member rotatably connected to the reservoir through a predetermined pivot, and at least one coupling member for coupling the retainer member and the tank cover with each other so that the pivot can be moved in a vertical direction of the fuel tank relative to the tank cover.

Abstract: A filter assembly comprises a filter case having an opening end portion; a filter element inserted into the filter case; a set plate mounted to the opening end portion of the filter case and having an inlet and an outlet of fluid to be filtered; and a seal plate attached to the set plate and fixed to the opening end portion of the filter case by curling up an outer periphery portion thereof together with an edge portion of the opening end portion of the filter case. The set plate is mounted to the filter case with press fitting to ensure the mechanical contact to prevent the leakage of the fluid to be filtered. Thus, the filer assembly can effectively prevent leakage of fluid of high pressure, such as AT-fluid introduced therein.
