Abstract: A discharge valve of a high-pressure pump is placed in a discharge passage and is openable to enable flow of fuel from a pressurizing chamber to a discharge outlet in response to a fuel pressure difference between the pressurizing chamber side and the discharge outlet side. A relief is placed in a relief passage. The relief passage communicates between a branching portion, which is located on a side of the discharge valve where the discharge outlet is placed in the discharge passage, and a return portion, which merges with a damper chamber. The relief valve is openable to enable flow of the fuel from the branching portion to the return portion in response to a fuel pressure difference between the branching portion side and the return portion side. A discharge passage orifice is placed between the discharge valve and the branching portion in the discharge passage and constricts a flow passage cross-sectional area of the discharge passage.

Abstract: A liquid pump includes an electronically controlled throttle inlet valve to control pump output. With each reciprocation cycle, a plunger displaces a fixed volume of fluid. When less than this fixed volume is desired as the output from the pump, the electronically controlled throttle inlet valve throttles flow past a passive inlet check valve to reduce output. As a consequence, cavitation bubbles are generated during the intake stroke. Cavitation damage to surfaces that define the inlet port passage are avoided by a specifically shaped and sized cavitation flow adjuster extending from the valve member of the passive inlet check valve. By positioning the cavitation flow adjuster in the inlet port passage, a flow pattern is formed in a way to encourage cavitation bubble collapse away from surfaces that could result in unacceptable cavitation damage to the pump.

Abstract: When a starter is started, a start-control duration time is established based on a fuel pressure at engine starting and a target fuel pressure. The start-control duration time corresponds to a duration after the engine is started until a difference between an actual fuel pressure in an accumulator and a target fuel pressure becomes lower than a specified value in a case that the fuel pump discharges the fuel at a maximum rate. A fuel pump discharges the fuel at the maximum rate during the estimated start-control duration time.

Abstract: A fuel supply system is incorporated into a diesel engine including a low-pressure fuel pump 2, a high-pressure fuel pump 3, a common rail 4, fuel injection valves 5 and a fuel return line 14. The fuel supply system reduces the discharge rate of the low-pressure fuel pump 2 supplying the fuel to the high-pressure fuel pump 3 when the diesel engine is in an idling state and the temperature of the fuel is below a lower fuel temperature threshold and when the diesel engine is in an idling state and the temperature of the fuel is above an upper fuel temperature threshold. The flow rate of the feed fuel discharged from the low-pressure fuel pump is reduced when an idling state or a specific state where the fuel is at a specific temperature. Thus the fuel line system of the fuel supply system can be built in a lightweight arrangement and the piping of the fuel line system can be simplified.
