摘要： A suction head for connection to a fuel hose in a fuel tank has a base member made of an injection molding material. The base member has a peripheral wall surface provided with cutouts and also has an end face opening. A cap closes off the end face opening. A connecting socket for the fuel hose is provided on the suction head. A first filter element is received inside the base member. A second filter element covering the cutouts is provided and is made of a filter fabric, wherein the filter fabric is a twill weave fabric or a satin weave fabric. The filter fabric has a mesh size that is greater than 10 μm and smaller than 25 μm. A power tool with a four-stroke engine is provided with such a suction head in the fuel tank.

摘要： A filtering device 10 that includes a housing 12 having a plurality of subsections 32, 34, and 36 where each subsection is adapted to receive a filter element 26, 28, and 30. An inlet 18 is disposed at a first location on the housing 12, and an upstream air distribution system is placed in fluid communication with the inlet 18 and with each of the subsections 32, 34, and 36. A downstream air distribution system is located in fluid communication with each subsection 32, 34, and 36, and an outlet 20 in fluid communication with the downstream air distribution system. The upstream and downstream air distribution systems are constructed to cause the same airflow velocity through each subsection. Using such a construction, overall product service life may be increased while minimizing pressure resistance of the total filter.

摘要： A filtering device 10 that includes a housing 12 having a plurality of subsections 32, 34, and 36 where each subsection contains a filter element 26, 28, and 30. An inlet 18 is disposed at a first location on the housing 12, and an upstream air distribution system is placed in fluid communication with the inlet 18 and with each of the subsections 32, 34, and 36. A downstream air distribution system is located in fluid communication with each subsection 32, 34, and 36, and an outlet 20 is in fluid communication with the downstream air distribution system. The subsections are fashioned such that each subsection 32, 34, and 36 is not in fluid communication with each other. Using a filtering device so constructed, airflow through the device may be better managed to enable overall product service life to be increased while minimizing pressure resistance of the total filter.

摘要： A flow suppression device adapted to be connected to a high pressure fluid system includes an outer flow containment member of a porous and flexible construction. The outer flow containment member has an upstream end and a downstream end opposite the upstream end. The upstream end includes an inlet opening adapted to receive a flow stream of pressurized fluid from the high pressure fluid system and the downstream end being substantially closed. The flow suppression device also includes a primary inner flow containment member of a porous and flexible construction contained within the outer flow containment member. The primary inner flow containment member has an upstream end with an inlet opening adjacent the inlet opening of the outer flow containment member and a downstream end opposite the upstream end of the primary inner flow containment member.

摘要： The present invention provides a depth filter which contains fine particles and coarse particles, and which exhibits excellent filtration precision with respect to a high concentration fluid and/or a high viscosity fluid. This depth filter enables filtration for a long period of time, while maintaining a low filtration pressure.
The present invention is a depth filter which is obtained by winding a fiber sheet into a cylinder, and which comprises a pre-filtration layer and a microfiltration layer; the pre-filtration layer and the microfiltration layer are formed of a fiber sheet; the fiber sheet is composed of a nonwoven fabric or a web; the average fiber diameter of the fiber sheet continuously decreases from the pre-filtration layer toward the microfiltration layer; and the average weight per square meter of the fiber sheet continuously decreases from the pre-filtration layer toward the microfiltration layer.
