  • Patent number: 7922004
    Abstract: A diesel filter includes a filter member and a water reservoir formed below the filter member. The filter member has a case, a cap for closing the opening of the case, an element, and an element-holding member for holding an upper part of the element, and is detachably housed in the case. The element-holding member has an opening that allows fuel to flow out, and the fuel introduced from a fuel inlet port to a portion above the element-holding member is then introduced to the water reservoir via a passage formed between the inner peripheral surface of the case and the outer peripheral surface of the element.

  • Patent number: 7543561
    Abstract: A swirl generator is arranged in a duct through which air is sent from the exterior to an air cleaner. The swirl generator has a plurality of guide vanes, which change the flow direction of an air flow. Each of the guide vanes has a guide fin that adjusts the air flow and a deflecting fin that applies swirl force to the air flow. The deflecting fin is configured by an upstream portion and a downstream portion, which are connected together at a predetermined angle. The upstream portion and the downstream portion each have a cross section extending linearly along a cylindrical plane coaxial with a nose cone.
