摘要： In a conventional configuration, a lead line weld joined portion 55 between a lead line and an end of a terminal is disposed internally of an magnetic circuit, i.e., of a yoke portion 51. This increases the total length of the magnetic circuit, i.e., the yoke portion 51 by the axial dimension of the lead line weld joined portion 55. This will increase the magnetic resistance of the magnetic circuit, which leads to a problem with a reduction in the magnetic biasing force occurring between a first core portion 33 and an anchor 35. In the present invention, the lead line weld joined portion 55 is disposed externally of the magnetic circuit, i.e., of the yoke portion 51. This eliminates the necessity of a space adapted to receive the lead line weld joined portion 55 therein; therefore, the total length of the magnetic circuit can be reduced. It is possible, thus, to generate a sufficient magnetic biasing force between the first core portion 33 and the anchor 35.
摘要翻译：在常规结构中，引线和端子端之间的引线焊接部55设置在磁路部分51的内部，这就增加了磁路的总长度，即，轭部51通过引线焊接接合部55的轴向尺寸而增大。这将增加磁路的磁阻，这导致在第一芯部33和第二芯部33之间产生的磁偏压力的降低的问题。在本发明中，引线焊接接合部分55设置在磁路部分即磁轭部分51的外部。这消除了在其中接收引线焊接接合部分55的空间的必要性。因此，可以减小磁路的总长度。因此，可以在第一芯部33和锚35之间产生足够的磁力。

摘要： A high-pressure fuel supply pump which has no probability of discontinuity of a thin film of fuel at a sliding portion even when the fuel is not needed to be compressed to a high pressure is obtained. Two low-pressure fuel ports are provided on the high-pressure fuel supply pump in addition to a high-pressure discharge port to a high-pressure fuel capacity chamber. One of the two low-pressure fuel ports is connected to a low-pressure fuel capacity chamber and remaining one is connected to a low-pressure fuel supply pump. Accordingly, the interior of the high-pressure fuel supply pump is always filled with fresh fuel even in a mode in which a high-pressure fuel injecting valve does not inject fuel and only a low-pressure fuel injection valve injects fuel, so that a temperature rise of a plunger and a cylinder is prevented and locking of the plunger and the cylinder can be prevented.

摘要： High-response and high-power electromagnetically driven flow rate control valve with flange portion forming an attracting surface on an anchor, a first peripheral surface portion having a diameter smaller than the flange portion, and a cylindrical non-magnetic area opposing an outer peripheral surface of the flange portion with a third clearance interposed therebetween are provided, and a first fluid trap portion communicating with the back pressure chamber via the third clearance is provided. When the diameter of the flange portion is enlarged in order to enlarge the cross-sectional area of the attracting surface, fuel that is displaced by the anchor is increased, but is partly absorbed in the first fluid trap portion, so that the fuel passing through the fuel channel does not increase in comparison with fuel before the diameter of the flange portion is enlarged. Accordingly, the cross-sectional area of the attracting surface may be enlarged.

摘要： To obtain a small and high performance damper mechanism which reduces pressure pulsation in low pressure-side fuel in the high pressure fuel pump in a high pressure fuel supply system or a high pressure fuel pump provided with the small and high performance damper mechanism.Two metal diaphragms are welded together over the entire circumference to obtain a metal diaphragm assembly (also referred to as “double metal diaphragm damper”). The whole or part of the portion of the metal diaphragm assembly other than the weld (for example, the portion inside the weld) is clamped by a pressing member and thereby the assembly is secured in a housing enclosure. The housing enclosure may be formed integrally with the body of a high pressure pump.
