摘要： A valve body surrounds a first passage connecting with a cylinder of an engine. A valve member is adapted to be seated on and lifted from the valve seat. An injector body connects with the valve body. The injector body has a pressure control chamber for controlling hydraulic pressure applied to the valve member thereby controlling a lift of the valve member. The injector body has a second passage through which fuel in the pressure control chamber is exhausted. An actuator is adapted to communicating the pressure control chamber with the first passage through the second passage and blocking the pressure control chamber from the first passage. The first passage introduces fuel from the pressure control chamber into the cylinder through the second passage.

摘要： A fuel supply apparatus includes a component adjustment unit, a low-pressure side passage, and a valve. The unit adjusts component composition of fuel by separating a particular component from fuel. The unit includes a component separation wall, which divides an interior of a portion of a fuel supply passage between an anterior chamber and a posterior chamber. The wall includes a separation membrane, which the particular component of fuel in the anterior chamber selectively permeates to be separated. The particular component after passing through the wall is temporarily stored in the posterior chamber. When the low-pressure side passage connected to the posterior chamber is opened by the valve, the particular component is separated. Fuel, from which the particular component is separated, is supplied to an injection valve from the anterior chamber. When the low-pressure side passage is closed by the valve, the separation of the particular component is restricted.

摘要： In an accumulator fuel injection device, a valve member of a solenoid valve includes a shaft and a spherical member. The spherical member is slidably supported at the tip portion of the shaft. The spherical member is prevented from falling off by caulking the tip of the shaft. A flat plate working as a valve seat for the spherical member is provided so that the spherical member allows communication between a pressure control chamber and a low-pressure side when separated from the flat plate, while prohibiting the communication therebetween when seated on the flat plate. On the other hand, the flat plate is formed with fuel relief passages in a tight contact region between the flat plate and the spherical member. The fuel relief passages communicate with the low-pressure side even when the spherical member is seated on the flat plate. Thus, a hydraulic force applied to the spherical member in a solenoid valve opening direction when the spherical member is seated on the flat plate, is rendered smaller. Accordingly, a biasing force of a spring urging the valve member in a solenoid valve closing direction can be set smaller, and thus, a magnetic force of the solenoid valve for lifting the valve member against the biasing force of the spring can also be set smaller. The fuel relief passages may be provided on the spherical member.
摘要翻译：在蓄能器燃料喷射装置中，电磁阀的阀构件包括轴和球形构件。球形构件可滑动地支撑在轴的尖端部分。通过铆接轴的尖端防止球形部件脱落。设置作为球形部件的阀座工作的平板，使得当与平板分离时，球形部件允许压力控制室和低压侧之间的连通，同时在坐在平板上时禁止其间的连通。另一方面，平板在平板与球形构件之间的紧密接触区域中形成有燃料排出通道。即使当球形构件安置在平板上时，燃料消除通道与低压侧连通。因此，当球形构件安置在平板上时，以电磁阀打开方向施加到球形构件的液压力变小。因此，可以将推动阀构件的电磁阀关闭方向的弹簧的偏置力设定得较小，因此也可以将抵抗弹簧的偏压力提升阀构件的电磁阀的磁力设定得较小。燃料消除通道可以设置在球形构件上。

摘要： A variable-damping-force shock absorber includes a piezoelectric actuator for producing a displacement, a hydraulic pressure chamber filled with a working oil and having a volume variable in response to the displacement produced by said piezoelectric actuator, and a plunger slidably disposed in a sleeve and reciprocally movable in response to a change in the volume of said hydraulic pressure chamber. The sleeve and said plunger define therebetween a gap communicating with said hydraulic pressure chamber. A supply passage for supplying a working oil from an external working oil source into said hydraulic pressure chamber extends through the gap. A leakage of the working oil from the hydraulic pressure chamber through the gap can automatically be compensated for by working oil supplied through the supply passage. Since the working oil leaks from and is supplied into the hydraulic pressure chamber through the gap, the leakage and supply of the working oil are kept in equilibrium.
