摘要： It is an object of the present invention to improve responsiveness in valve opening and valve closing of an electromagnetically-driven intake valve unit (200) in which a valve (203) is provided on a pressurizing chamber side of a valve seat (214S). The valve includes an annular abutting surface (203R) that abuts the valve seat (214S) to shut off a fuel intake passage and a bottomed cylindrical part (203F,203H) provided at an inner peripheral part of the annular abutting surface (203R). The bottomed cylindrical part (203F,203H) is inserted into a fuel introduction hole (214P) formed in the valve housing (214) inside the valve seat (214S), and the outer surface of an end part of the bottomed cylindrical part (203F,203H) is exposed to fuel in a low pressure fuel chamber (10A) provided upstream of the fuel introduction hole (214P). Thus, a low pressure is less produced upstream of the valve seat (214S) and thereby a static or dynamic fluid force of the fluid for biasing the valve (203) toward the valve opening direction is exerted on the entire outer surface of the valve (203), so that it is possible to provide a fast and stable valve opening speed of the valve (203).

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：在传统的结构中，引线和端子端之间的引线焊接部55设置在磁路部分51的磁路的内部，这就增加了磁路的总长度，即，通过引线焊接接合部分55的轴向尺寸，磁轭部分51.这将增加磁路的磁阻，这导致在第一芯部分33和第二芯部分33之间产生的磁偏置力的减小的问题。在本发明中，引线焊接接合部分55设置在磁路部分的外侧，即磁轭部分51的外部。这消除了在其中容纳引线焊接接合部分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作用力。

摘要： In a high pressure fuel supply pump for transmitting rotation of a cam 7 to a reciprocating plunger 2 via a tappet 6 and a retainer 3, a diametric force acting on the plunger 2 is reduced. The high pressure fuel supply pump includes the retainer 3 disposed on the plunger 2 and a return spring 4 exerting an urging force on the retainer 3 in a direction of the tappet 6. A clearance between a plunger leading end 201 and a tappet bottom surface 601 opposed thereto is set to be greater than a clearance between a retainer bottom surface 301 and the tappet bottom surface 602 opposed thereto, and a clearance between a retainer inside diameter section 302 and a plunger peripheral surface section 203 opposed thereto is set to be greater than a clearance between a retainer outside diameter section 303 and a tappet inner wall 603 opposed thereto. The foregoing arrangements make a plunger diametric force involved in flexural deformation or shear deformation of the spring 4 less easy to be transmitted to the plunger 2. As a result, a fault of the plunger 2 galling a cylinder inner wall 2A can be reduced.

摘要： It is an object of the present invention to eliminate a valve holder and accommodate a valve guide in a small space provided between a valve seat and a peripheral surface part of a pressure chamber to thereby bring a pump into less size. In order to achieve the above object, the valve guide (SG) which guides a stroke of a valve (203) is provided inside the valve seat (214S). Specifically, a valve (203) includes an annular abutting surface (203R) that abuts a valve seat (214S) formed in a valve housing (214) to shut off a fuel intake passage and a bottomed cylindrical part (203F,203H) provided at an inner peripheral part of the annular abutting surface (203R). The bottomed cylindrical part (203F,203H) is inserted into a fuel introduction hole (214P) formed in the valve housing (214) inside the valve seat (214S). A member having a cylindrical surface part which supports a reciprocating motion of the valve (203), is fixed to the valve housing (214), in face-to-face with an inner peripheral part of the bottomed cylindrical part (203F,203H). Thus, the size of the valve guide (SG) that protrudes from the surface of the valve seat (214S) to the pressure chamber side can be shortened. It is therefore possible to bring an inlet valve mechanism portion into less size and eventually render the pump in a small size.
