摘要： A fuel line check valve system and a fuel system that includes the fuel line diaphragm valve system are described. The fuel line diaphragm valve system may prevent flow into a fuel system that is generated via a vacuum in the fuel system. The fuel line diaphragm valve may also remain in an open state after it is open via a reduced pressure.

摘要： A distal end portion of an injector is fitted into a mounting member. A fuel joint having a connecting pipe portion is connected to a proximal portion of the injector. A joint pressing member which restricts the displacement of the fuel joint in the direction away from the mounting member is fixed by fastening to the mounting member. The injector is fixed to the mounting member by restricting the displacement of the fuel joint by the joint pressing member.

摘要： A coupling device for hydraulically and mechanically coupling an injection valve to a fuel rail of a combustion engine has a fuel injector cup with a central longitudinal axis and can be hydraulically coupled to the fuel rail and engages a fuel inlet tube of the injection valve, a first retaining element is fixedly coupled to the cup, a second retaining element is fixedly coupled to the valve, the second element being coupled to the first element to prevent a movement of the second element relative to the first element in a first direction of the central longitudinal axis to retain the valve in the cup, and a damper element which is arranged axially between the cup and the valve body. The damper element limits a movement of the valve relative to the cup in a second direction of the central longitudinal axis opposing the first direction.

摘要： A high-pressure return passage returns excess fuel in a delivery pipe that is connected to an injector to a fuel tank. An upstream end of the high-pressure return passage is connected to the delivery pipe via a high-pressure regulator. A vertically lower portion of the high-pressure return passage is vertically below the upstream end and the downstream end. A low-pressure return passage returns excess fuel in a main passage to the fuel tank. The switch valve switches the open state and the closed state of the low-pressure return passage. A control section controls the switch valve to the closed state after the engine is stopped and drives the fuel pump so as to execute a forced return process that flows fuel into the high-pressure return passage.
