摘要： A pressure regulating valve includes a casing, a holder, a fixed valve, a movable valve, a spring member, a diaphragm, and a filter. The filter is configured to filter fluid flowing from a flow inlet of the casing into a pressure chamber. The filter includes a filtering part for filtering fluid and a holding part including a frame part for holding an outer periphery of the filtering part. An alignment structure configured to align the holding part at a predetermined position is provided between the holding part of the filter and the holder, or between the holding part of the filter and the casing.

摘要： A fuel supply device has a cover member which is attached to an opening portion of a fuel tank and a pump unit comprising a pump. The cover member and pump unit are connected via a connecting portion where the pump unit is rotatably connected to the connecting portion. Further, the fuel supply device includes a fuel residual amount detection device which is attached to the pump unit and configured to detect the residual amount of fuel. The fuel residual amount detection device includes a gauge main body to which electric wirings are connected, an arm portion which is movably mounted relative to the gauge main body and a float which is attached to a leading end of the arm portion. The float is positioned above a lower terminal end of the base portion when the cover member is held and lifted while the pump unit rotates with respect to the connecting portion.

摘要： A fuel supply device includes a cover member which is attached to an opening of a fuel tank, a pump unit comprising a pump, and a connecting portion for connecting the cover member and the pump unit. The pump unit is connected to the connecting portion so as to be relatively movable to the cover member. When the fuel supply device is attached to the fuel tank, an engagement portion provided at a lower portion of the pump unit abuts the connecting portion such that via the engagement portion the connecting portion presses the pump unit against the fuel tank.

摘要： A fuel supply device has a cover member which is attached to an opening of a fuel tank, a pump unit comprising a pump, and a connecting portion configured to connect the cover member and the pump unit. A connecting shaft which is formed to one of the two connected members of the connecting portion is inserted into a connecting hole which is formed to the other of the two such that the pump unit is connected to be relatively movable to the connecting portion. The pump unit includes an upper base on which the pump is placed, and a lower base which contacts to the fuel tank. The upper base and the lower base are coupled through attachments whereby an engagement portion of the upper base is fitted into a recessed portion formed on the side of the lower base. The recessed portion has a pair of planes opposing to each other and oriented toward a bottom surface of the lower base from a predetermined position. The recessed portion is further configured such that an interval between a pair of the planes is gradually increased toward the bottom surface.

摘要： When a fuel tank is inclined at a negative slope and tilted to the right side, it may be tilted such that a position of a mesh member is relatively higher than a position of a vapor outlet of a vapor outlet passage. In this case, air may enter into a leak passage from an outlet port such that interfacial tension is generated in the mesh member. The interface between fuel and air is present at the mesh member, and the interfacial tension generated at the interface serves to prevent air from entering into a discharge pipe.

摘要： A fuel supply device includes a flange unit and a pump unit. The flange unit includes a flange main body for closing an opening formed in an upper wall of a fuel tank. The pump unit includes a joint member that is connected to the flange main body so that both components may be movable relative to each other in the vertical direction. The interval in the vertical direction between the flange main body and the joint member is restricted from going below a minimum vertical interval. The minimum interval occurs when a stand-off portion provided as part of the flange main body and a connecting plate portion provided as part of the joint member come into mutual contact with each other and abut each other in the vertical direction.

摘要： A fuel supply device has a cover member which is attached to an opening of a fuel tank, a pump unit provided with a pump, and a connecting portion for connecting the cover member and the pump unit. The fuel supply device has a connecting shaft which is formed on either one of the connecting portion or the pump unit, and a connecting hole which is formed on the other. The fuel supply device has a guide mechanism which can guide the pump unit. The guide mechanism includes a first guide portion formed at the connecting portion and a second guide portion formed at the pump unit. One of the first guide portion or the second guide portion includes a protruding portion which protrudes in a position spaced apart from the connecting shaft. The other guide portion is formed to restrict a movable range of the protruding portion.

摘要： A fuel supply device includes a flange unit configured to be attached to an upper wall of a fuel tank to close an opening of the fuel tank, a pump unit configured to be disposed within the fuel tank, and a coupling mechanism moveably coupling the pump unit to the flange unit in a vertically slidable manner. The coupling mechanism includes a fixed-side rail member having a rail portion extending vertically from the flange unit, and a movable-side rail member having a channel-groove shaped rail groove extending from the pump unit. The channel-groove shaped rail groove is slidably engaged with the rail portion of the fixed-side rail member. A recess having a semi-circular cross section is formed at a corner of the rail groove of the movable-side rail member.
