摘要： An injector has an inner sleeve between a needle pressure receiving face of a needle and a rear end face of a valve body. The inner sleeve is slidably fitted to an outer periphery of a middle shaft section of the needle. The inner sleeve receives a reaction force of a spring located between the inner sleeve and a pressurizing piston, so an axial tip end (edge section) of the inner sleeve is pressed against the rear end face to achieve close contact therebetween. Thus, a volume of a pressure chamber can be reduced, so a valve opening force for lifting the needle can be acquired efficiently. Accordingly, injection of a large flow rate can be performed by increasing a lift amount of the needle and also quick lifting of the needle can be performed.
摘要翻译：注射器具有在针的针受压面和阀体的后端面之间的内套筒。内套筒可滑动地装配到针的中间轴部分的外周。内套管接收位于内套筒和加压活塞之间的弹簧的反作用力，因此内套筒的轴向前端（边缘部分）被压靠在后端面上，以实现紧密接触。因此，可以减小压力室的体积，因此可以有效地获得用于提升针的开启力。因此，可以通过增加针的提升量来进行大流量的注入，并且可以进行针的快速提升。

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： A fuel injector injects high-pressure gaseous fuel directly into a cylinder of an engine. A small amount of liquid fuel is used in the injector to lubricate sliding portions of the fuel injector in addition to utilizing it as a medium for transmitting driving force. The fuel injector includes a nozzle member having injection holes at its elongated end and a needle slidably disposed in an elongated center hole of the nozzle member. The needle is driven by pressure of the liquid fuel introduced into a control chamber to open or close the injection holes. The pressure in the control chamber is controlled by a switching valve which is in turn driven by an actuator such as an electromagnetic or piezoelectric actuator. The liquid fuel is injected together with the high-pressure gaseous fuel after lubricating the sliding portions between the nozzle member and the needle.

摘要： A water separation unit includes a water separation portion. The water separation portion includes a component separation wall, a liquid chamber, and a gas chamber. The separation wall divides the water separation portion between the liquid chamber and the gas chamber. Liquid fuel is led to the liquid chamber. The separation wall includes a separation membrane, which water selectively permeates to be separated from liquid fuel in the liquid chamber. Water passing through the separation wall is temporarily stored in the gas chamber. A fuel supply apparatus supplies liquid fuel in a fuel tank to an internal-combustion engine. The apparatus includes the water separation unit. The water separation portion is disposed integrally in one of the fuel tank and a passage leading from a filler opening into the fuel tank, such that the liquid chamber is located above the gas chamber in a vertical direction of the water separation portion.

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.
