    • PROBLEM TO BE SOLVED: To avoid overheating of a secondary medium in an actuation chamber.SOLUTION: The invention relates to an injection system (1) for an internal combustion engine, especially an internal combustion engine operated with liquefied gas as the fuel or as a fuel component, comprising one injection device (2) per cylinder for directly injecting fuel into a combustion chamber, and a fuel supply system (3) which has at least one fuel tank and an oscillating pump member (5), configured as a displacer, for delivering the fuel. The pump member (5) can be hydraulically actuated by a secondary medium and the pump member (5) adjoins to an actuation chamber (9), impinged upon with pressure of the secondary medium as a hydraulic pipe (8) carrying the secondary medium is opened to the actuation chamber, and a main pump (7) is arranged in the hydraulic pipe (8). For preventing the secondary medium from overheating, a scavenging pipe (18) is opened in the actuation chamber (9), a shut-off mechanism (19) is disposed in the scavenging pipe, and the actuation chamber (9) can be scavenged with the secondary medium during at least one injection interval.
    • 要解决的问题:为了避免致动室中的二次介质的过热。 解决方案:本发明涉及一种用于内燃机的喷射系统(1),特别是用作为燃料或燃料部件的液化气体操作的内燃机,其包括每个气缸的一个喷射装置(2),用于直接 将燃料喷射到燃烧室中,以及燃料供给系统(3),其具有至少一个燃料箱和构造为用于输送燃料的置换器的振荡泵构件(5)。 泵构件(5)可以由辅助介质液压致动,并且泵构件(5)邻近致动室(9),当辅助介质承载第二介质的液压管道(8)为 开启到致动室,并且主液压泵(7)布置在液压管(8)中。 为了防止二次介质过热,清扫管(18)在致动室(9)中打开,切断机构(19)设置在扫气管中,并且致动室(9)能够被清扫 在至少一个注射间隔期间的第二介质。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To effectively use a spring sandwiched between a fuel injection valve and a fuel distributing pipe for avoiding leakage in the communication pipe strip of a fuel distribution conduit and for suppressing the axial deviation of the fuel injection valve in a certain limit range.
      SOLUTION: This fuel injection valve 1 is used for the direct injection of a fuel. The fuel injection valve is arranged in a receiving hole of a cylinder head 2 of an internal combustion engine, has a nozzle base 10 and a sealing ring 14 which seals the fuel injection valve against the cylinder head of the internal combustion engine. In this type of an engine, between the fuel distribution conduit 4 and the fuel injection valve, a spring is set in extension for fitting the position of the fuel injection valve to the communication pipe strip 26 of the fuel distribution conduit in elasticity.

    • PROBLEM TO BE SOLVED: To provide a mounting structure of a fuel injection valve capable of suppressing a rise of temperature of a nozzle part of the fuel injection valve and attaching the fuel injection valve to a cylinder head easily. SOLUTION: This fuel injection valve 3 is attached to a mounting hole 4 formed in the cylinder head 1. The fuel injection valve 3 is fixed to the cylinder head 1 by a bolt 4. A fitting plug 90 is fitted into a small diameter part 41 of the mounting hole 4. A pressing-in plug 80 is pressed into an inner peripheral side of the fitting plug 90. The pressing-in plug 80 is in contact with an inner peripheral face of the fitting plug 90 at the whole periphery. An exposed hole 81 is formed in the pressing-in plug 80, and a distal end of a nozzle 30 is inserted into the exposed hole 81. The distal end of the nozzle 30 is in contact with an inner peripheral face of the exposed hole 81 at the whole periphery. COPYRIGHT: (C)2006,JPO&NCIPI
