摘要： A pressure control valve is provided in a fuel return pipe connected between a high pressure fuel pipe and a fuel pressurizing chamber of a high pressure pump. A pressure relief valve is opened when fuel pressure in a fuel delivery pipe is higher than a first pressure. A first valve body of the pressure relief valve is brought into contact with a stopper so that a movement of the first valve body is limited. A pressure holding valve, which is provided in an inside of the first valve body, is opened when the fuel pressure in the fuel delivery pipe is larger than a second pressure. When the pressure relief valve is opened and the first valve body crashes into the stopper, a lifting amount of a second valve body of the pressure holding valve is increased by inertia of the second valve body, so that extraneous material attached to the second valve body can be removed.
摘要翻译：压力控制阀设置在连接在高压燃料管和高压泵的燃料加压室之间的燃料回流管中。当燃料输送管中的燃料压力高于第一压力时，打开压力释放阀。减压阀的第一阀体与止动件接触，使得第一阀体的运动受到限制。当燃料输送管中的燃料压力大于第二压力时，设置在第一阀体内部的压力保持阀打开。当压力释放阀打开并且第一阀体碰撞到止动器中时，压力保持阀的第二阀体的提升量由于第二阀体的惯性而增加，从而附着到第二阀体上的外来材料可以删除

摘要： A valve member of a pressure relief valve has a shaft portion, a pressure receiving portion, and a guide portion, wherein the valve member is axially movable in a fuel return passage. When a forward end of the shaft portion is seated on a valve seta, the fuel return passage is closed, while the shaft portion is separated from the valve seat the fuel return passage is opened. A notched portion is formed at an outer wall of the guide portion to thereby form an outer-surface passage. A fuel inlet port is formed in the valve member for communicating a fuel inlet chamber to the fuel return passage at a downstream side of the valve member.

摘要： A housing has a compression chamber and a first passage, through which the compression chamber communicates with an accumulation chamber. A discharge valve is provided in the first passage and configured to open to supply fuel from the compression chamber to the accumulation chamber in response to increase in pressure in the compression chamber. A second passage is configured to communicate the accumulation chamber with the compression chamber via the discharge valve. A valve element allows fuel flow from the accumulation chamber to the compression chamber. A biasing unit biases the valve element to seat the valve element on a valve seat of the second passage. The sidewall of the valve element and the inner wall defining the second passage therebetween define a throttle midway through the second passage for restricting fuel flow from the accumulation chamber to the compression chamber.

摘要： A fuel gallery has an inlet opening through which a fuel is introduced therein and a suction opening through which the fuel flows between the fuel gallery and a compression chamber. A pulsation damper is supported in the fuel gallery by a first and a second supporting member. The second supporting member defines an inner fuel chamber and outer fuel chamber which communicates with each other through apertures. The suction opening is located at a side wall of the fuel gallery and the inlet opening is located at a bottom wall of the inner fuel chamber which is defined radially inside of the second supporting member. The fuel discharged into the outer fuel chamber through the suction opening is introduced into the inner fuel chamber through the apertures. A flow velocity of the fuel is decreased and a pressure pulsation reduction effect of the pulsation damper is surely achieved.
