摘要： A fuel level detecting device has a first locking mechanism including a locking member, clamping portions for clamping a mounting surface, and pawl arms which are on a body of the device. A slit and engagement portions are provided on the mounting face of the mounting member, which acts as a second locking mechanism. The thickness of the locking member is equal to or slightly larger than the width of the slit, and the gap between a clamping portion and a contact face is equal to or slightly smaller than the thickness of the mounting face. The body is mounted to the mounting member when the locking member is inserted into the slit. This ensures the fuel detecting device to be mounted without play and disconnection thereof even when vibration occurs.

摘要： A compact pressure regulating valve makes installation work simple and has a hermetic structure of a stationary value member without a specific seal member. A pressure regulator (201) has a body (203) which includes a fuel inlet (215) and an inner periphery for positioning a stationary valve member (205) in a radial direction. When the movable valve member (208) leaves the stationary valve member (205), the valve opens. Operation of the movable valve member (208) is controlled by a diaphragm which moves to balance the pressure of the pressure chamber (211) and the pressure of a back pressure chamber (213) combined with a biasing pressure of a compression coil spring (214). As a result, the pressure of the pressure chamber (211) can be controlled without a specific sealing member or complex structure. In addition, a pressure regulating valve according to the present invention is compact and easy to install, and has no specific member to seal the stationary valve member.

摘要： A cover for a fuel tank opening is molded with insulating resin and a plurality of terminal pins is directly inserted thereinto. A lower housing portion, made of conductive resin and containing a fuel filter element, is weld-connected to the fuel tank side of the cover. A fuel pump is held under the cover. When electricity is supplied to the fuel pump via an electric connector, fuel is discharged from the fuel pump and this discharged fuel is filtered by a fuel filter. Static electricity generated in the fuel filter dissipates through the lower housing portion made of conductive resin. This construction enables suppression of electrostatic voltage generated in the fuel filter. Moreover, a plurality of connector terminals are directly inserted into the upper housing cover portion of the fuel filter housing at the time of molding, which can therefore supply electric power to the fuel pump with a simplified construction.

摘要： Resin having a susceptibility to electrostatic charge which is opposite in polarity to the susceptibility to electrostatic charge of a filter sheet or member forming a filter element is impregnated into the filter member. For example, when the filter member is composed of polyester of 50-70 weight percentage and glass fiber of 5-25 weight percentage as well as pulp of 15-35 weight percentage, resin composed of phenol resin of 5-20 weight percentage and melamine resin of 80-95 weight percentage is impregnated into the filter member so that the susceptibility to electrostatic charge of the filter member can be neutralized. Thus, static electricity generated by friction between the filter element and fuel flowing therethrough can be controlled.

摘要： An oil deterioration detector comprising a sensitive electrode whose electric potential varies in response to acidity and/or basicity of oil to be measured, and a reference electrode associated with this sensitive electrode. An electrically conductive housing accommodates the sensitive electrode and the reference electrode together with the oil. A potential difference detector detects oil deterioration by measuring a potential difference between the sensitive electrode and the reference electrode. And, an insulating member is interposed between these electrodes and the electrically conductive housing for electrically insulating these electrodes from the electrically conductive housing. The reference electrode is grounded together with the electrically conductive housing. An insulating, hydrophilic porous member would be interposed between the sensitive electrode and the reference electrode.

摘要： A fuel pump module comprising a fuel pump, a pressure regulator, a supply line check valve, a relief valve, and a flange adapted to engage a fuel supply line that fluidly links the fuel pump module with an injector rail. The pressure regulator is adapted to maintain a predetermined fuel pressure between the fuel pump and the supply line check valve. The supply line check valve is adapted to facilitate a minimum fuel pressure in the fuel supply line. The relief valve is adapted to limit the maximum fuel pressure in the fuel supply line. The supply line check valve, the relief valve, and the flange are integrated to form a single fluidly interconnected structure disposed within a fluid path between the pressure regulator and the fuel supply line. An integrated casing may house the fuel pump and the pressure regulator.

摘要： A fuel pump module with integrated vapor vent manifold for minimizing fuel vapor emission in a fuel venting system, comprising a modular flange having a plurality of vapor inlets on the bottom side for receiving fuel vapor from sources both proximal and distal to the flange within the fuel tank. The vapors collected from distal sources within the tank are carried to the manifold by means of internal vent lines thereby minimizing permeation emissions common of external vapor lines. Once received in the manifold, the vapors conglomerate and exit the top side of the flange through a single outlet, connected by a single vapor line to a remote canister for storage.
