摘要： A system for delivering fuel to an engine including a fuel reservoir pump configured to pump fuel from a fuel tank to a fuel pump reservoir. A low pressure fuel pump is configured to pump fuel out from within the fuel pump reservoir and to the fuel reservoir pump. A high pressure fuel pump is configured to pump fuel to the engine. The low pressure fuel pump is configured to pump fuel to the high pressure fuel pump. A controller is operable to configure the low pressure fuel pump in a high mode at a first pump rate when the high pressure fuel pump is in a first configuration, and operable to configure the low pressure fuel pump in a low mode at a second pump rate when the high pressure fuel pump is in a second configuration different from the first configuration, the first pump rate is different from the second pump rate.

摘要： A pump may have a first chamber and a solenoid coil to control movement of a first valve member. A second chamber may have a second valve member to control fluid moving into a third chamber. A first fluid passageway may link the first and second chambers, a second passageway may link second and third chambers and a third passageway may link third and fourth chambers. After pressurizing the third chamber causing fluid to flow into and leave a fourth chamber, the third chamber depressurizes due to downward movement of a plunger. Upon depressurization with a solenoid coil energized, second valve member floats and then moves against a valve seat. While the second valve member is moving toward the valve seat, the solenoid coil is de-energized causing the first valve member to move and strike the second valve member when the second valve member is moving at maximum velocity.

摘要： A cup is in a bottomed tubular shape to receive an injector along an injector axis. A bracket is extended from a sidewall of the cup. The bracket includes at least one arm and a body. The at least one arm connects the body with the cup. The body forms a screw opening configured to receive a screw along a screw axis. The body has a pivot end on an opposite side of the screw axis from the injector axis.

摘要翻译：泵可以具有第一室和电磁线圈，以控制第一阀构件的运动。第二室可以具有第二阀构件以控制流入第三室的流体。第一流体通道可以连接第一和第二腔室，第二通道可以连接第二和第三腔室，第三通道可以连接第三和第四腔室。在加压第三室，使流体流入并离开第四室之后，第三室由于柱塞的向下运动而减压。在用螺线管线圈通电的情况下进行减压，第二阀构件浮动然后抵靠阀座移动。当第二阀构件朝向阀座移动时，当第二阀构件以最大速度移动时，螺线管线圈断电，使得第一阀构件移动并撞击第二阀构件。

摘要： A fuel delivery system including a high pressure fuel pump assembly. The assembly includes first and second output fuel paths each in communication with a fuel pump chamber. A main pressure relief fuel path is in communication with the fuel pump chamber and includes a pressure relief valve. A first relief fuel path is in communication with both the first output fuel path and the main pressure relief fuel path. A second relief fuel path is in communication with both the second output fuel path and the main pressure relief fuel path. The first and the second relief fuel paths are configured to restrict fuel flow therethrough between the first and the second output fuel paths.

摘要： An inter-connect circuit (ICC) device for a fuel delivery system of a vehicle is disposed between an engine control unit (ECU) and a fuel control device. The ECU transmits a drive pulse to the fuel control device by way of a drive pulse line passing through the ICC device. The ICC device includes a housing and a sense circuit. The housing has a first side that is connectable to the ECU and a second side different from the first side that is connectable to the fuel control device. The sense circuit is disposed within the housing. The sense circuit is electrically coupled to the drive pulse line by way of a sense circuit line and is communicably coupled to the ECU by way of a data communication line.
