Abstract: PROBLEM TO BE SOLVED: To eliminate the fear of the wear and the stripping of a slide film caused by the deterioration of slide environment in a conventional gasoline lubricating slide member. SOLUTION: The gasoline lubricating slide member is provided with a slide part and a diamond like carbon film (DLC film) formed on a slide surface of the slide part. That is, the gasoline lubricating slide member has not a resin or ceramic coating film, but the DLC film formed on the slide surface of the slide member. The DLC film has remarkably high hardness and low friction coefficient. The gasoline lubricating slide member having excellent wear resistance and seizure resistance in a gasoline bath is provided by forming the DLC film on the slide surface of the slide part.

Abstract: PROBLEM TO BE SOLVED: To provide a pressure control device capable of preventing a filter from breakage and removing foreign matter of minute size. SOLUTION: A pressure control valve 20 is installed on a delivery pipe, and a housing 21 of the valve 20 accommodates a filter 30, valve seat member 22, ball 40, spring 41, etc. When the pressure of the fuel accumulated in a pressure chamber of the delivery pipe exceeds a specified level, the ball 40 separates from the seat 26 against the energizing force of the spring 41. The fuel having flowed into the filter 30 from a fuel inlet 50 is intercepted by a disc part 32 of the filter 30, the inner peripheral wall and bottom 24 of a cylindrical part 23 so that the flowing direction is changed. In the position where the fuel is intercepted by the bottom 24 and its flowing direction changes, foreign matter 52 of minute size having passed the mesh part 34 of the filter 30 is deposited in a recess 27 by the inertial force of the fuel flow directed to the bottom 24.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device reducing pressure pulsation in a fuel chamber and reducing noise radiated to an outside. SOLUTION: Fuel is supplied from an open close valve 42 when fuel is injected from injectors 61-64 and pressure of fuel in a fuel chamber 33 drops. The open close valve 42 is supplied with fuel of higher pressure than the fuel chamber 33 via a fuel passage 43 branching off of a fuel pump 12 side of a pressure reducing valve 35. Consequently, pressure pulsation of fuel in the fuel chamber 33 is reduced even if fuel is injected from the injectors 61-64. Consequently, vibration of the rail 32 accompanying expansion and contraction of the rail 32 forming the fuel chamber 33 and expansion and contraction of the rail 32 can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device for reducing a resonance phenomenon without increasing a weight.
SOLUTION: Axial lengths of rails 20 are different between a bracket 21 and a bracket 22. Therefore, weights of the brackets 21 and 22 are different from each other, and rigidities and natural frequencies are different between first and second areas of this fuel supply device 10. As a result, a resonance acceleration due to oscillation is restrained between a joint part of the rail 20 and the bracket 21 in the first area of the fuel supply device 10 and a joint part of the rail 20 and the bracket 22 in the second area. Thereby, when the brackets 21 and 22 are installed at a symmetrical position from a center g of the rail 20, the resonance of the brackets 21 and 22 can be reduced. Accordingly, the weight can be restrained from increasing without heightening strengths of the brackets 21 and 22.

Abstract: PROBLEM TO BE SOLVED: To effectively reduce the noise of a fuel pressure regulator regardless of a flow rate of fuel. SOLUTION: A flow collision preventing member 35 is fitted to an upper edge opening of a bush 26, and an upper part of the flow collision preventing member 35 is projected to a valve element 33 side with respect to a valve seat 28 (upper end face of bush 26). A plurality of channels 36 are formed on an outer peripheral part of the flow collision preventing member 35 at equal intervals to allow the fuel to axially (downward) flow along an inner peripheral face of the bush 26. The valve element 33 positioned immediately above the valve seat 28 is provided with a relief recessed part 37 relieved from a projecting part of the flow collision preventing member 35. Since an upper part of the flow collision preventing member 35 is projected to an inner peripheral side of an annular clearance formed between the valve element 33 and the valve seat 28, the collision of the flow of the fuel flowing at each part of the annular clearance toward the inner peripheral direction is prevented by the flow collision preventing member 35, and pressure pulsation caused by the collision of the flow of the fuel is not generated at a lower side of the valve element 33, whereby the noise caused by the pressure pulsation can be reduced.
