摘要： PROBLEM TO BE SOLVED: To provide a reliability enhancing measure that assumes a situation that a plunger head is detached from a plunger in a fuel supply pump.SOLUTION: In a fuel supply pump 1, when an imaginary situation, in which a plunger head 19 is separated from a plunger 13 and a cam 22 is continuously revolved while being in a quiescent relatively with respect to an abutting surface 31 and abutted thereon, is assumed, first recesses 38a, 38b are formed in cam chamber forming faces 37a, 37b so that the plunger head 19 is not abutted on the cam chamber forming faces 37a, 37b in each imaginary situation. Thus, the plunger head 19 is separated from the plunger 13, and integrated with a cam ring 23, and not abutted on the cam chamber forming faces 37a, 37b even when being reciprocated in the third direction. Therefore, in the fuel supply pump 1, the reliability can be enhanced, assuming the situation that the plunger head 19 is separated from the plunger 13.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection pump, wherein a mounting portion of a fuel pressure control valve has a sufficiently improved machinability.
SOLUTION: A rear cover 70 formed as a member separate from a pump housing 3a which forms the shell of a fuel injection pump and a feed pump cover 53 as a mounting member via which a feed pump part is mounted on the pump housing 3a, has a mounting hole 70a in which a return valve 15 is mounted. Thus, it becomes unnecessary to avoid an interference with a plurality of fuel passages provided in the pump housing 3a or to consider the deformation of the internal shape of a low pressure pump cover 53, when machining and forming the mounting hole 70a. This sufficiently improves the machinability of the mounting hole 70a.

摘要： PROBLEM TO BE SOLVED: To prevent or suppress the abrasion and seizure of a sliding portion caused by a temperature rise of fuel in a cam chamber.
SOLUTION: In the fuel supply system, return passages 26, 102 returning fuel to a fuel tank are connected to one cylinder chamber 13a of a plurality of cylinder chambers 13, and the one cylinder chamber 13a and the other cylinder chamber 13b are connected to each other by bypassing a cam chamber 12 through a bypass passage 101. With this structure, since fuel leaked from a pump, led to flow into the one cylinder chamber 13a, flows into the return passages 26, 102 and is returned to the fuel tank, the fuel leaked from the pump hardly flows into the cam chamber 12. Also, since fuel leaked from the pump, led to flow into the other cylinder chamber 13b, is led to flow into the one cylinder chamber 13a through the bypass passage 101, further flows from the one cylinder chamber 13a to the return passages 26, 102 and is returned to the fuel tank, the fuel leaked from the pump hardly flows into the cam chamber 12. Thereby, the temperature rise of fuel in the cam chamber 12 caused by high-temperature leaked fuel is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a return recirculation valve not causing clogging of a fuel filter even under low temperature environment.
SOLUTION: This return recirculation valve includes a fuel supply passage establishing communication between a fuel tank and an engine, a return passage establishing communication between the engine and the fuel tank, a communication passage establishing communication between the fuel supply passage and a return passage, a temperature sensitive displacement means provided in the fuel supply passage and the open close valve opening and closing the communication passage with interlocking with the temperature sensitive displacement means. The open close valve blocks the communication passage when fuel temperature in the fuel supply passage is predetermined value or more and opens the communication passage to supply part of fuel in the return passage together with fuel from the fuel tank to the engine via a fuel filter, when fuel temperature in the fuel supply passage is the predetermined value or less.

摘要： PROBLEM TO BE SOLVED: To provide a feed pump 3 improving pump performance by reducing side clearances in an axial direction at both sides of a pump element PE. SOLUTION: The feed pump 3 as this fuel supply device is constructed in such a manner that an outer rotor 22 and an inner rotor 23 constructing the pump element PE have through holes 22a, 23a formed on a tooth tip part of the outer rotor 22 and a tooth tip part of the inner rotor 23 respectively. Consequently, since side clearances provided in both axial sides of the rotors 22, 23 are communicated with each other, pressure in a thrust direction can be equalized in the both sides of the both rotors 22, 23 in the axial direction. Consequently, the both rotors 22, 23 do not have metal-to-metal contact with a pump cover 19 and a pump plate 20 and can be floated, troubles such as abnormal wear and seizure can be suppressed even if side clearance between the pump cover 19 and the pump element PE is set small.

摘要翻译：要解决的问题：提供一种通过减少泵元件PE的两侧的轴向方向上的间隙来提高泵性能的进给泵3。解决方案：作为该燃料供给装置的供给泵3构成为构成泵元件PE的外转子22和内转子23具有形成在外侧的齿顶部的通孔22a，23a 转子22和内转子23的齿尖部分。因此，由于设置在转子22,23的两个轴向侧的侧面间隙彼此连通，所以在两个转子22,23的轴向的两侧都能够推压推压方向上的压力。因此，两个转子22,23与泵盖19和泵板20不具有金属对金属的接触，并且可以浮起，即使泵盖之间的侧向间隙也能够抑制诸如异常磨损和卡死的问题并且泵元件PE被设定得小。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce intake pressure loss of a feed pump while suppressing size increase of a fuel supply device adopted for a pressure accumulation type fuel injection system. SOLUTION: A return passage 14 is provided for returning fuel from a downstream side of the feed pump 5 to an upstream side of the feed pump 5 and a return valve 15 for adjusting a fuel flow rate returning to the upstream side of the feed pump 5 is provided at the return passage. Thus, the fuel from the downstream side of the feed pump 5 can be returned to the upstream side of the feed pump 5, it is possible to reduce the intake pressure loss of the feed pump 5. Further, size increase of the fuel supply device can be suppressed as enlargement of the diameter of an intake piping 4a of the feed pump 5 is not necessary. COPYRIGHT: (C)2008,JPO&INPIT
