摘要： In a high pressure fuel supply pump for transmitting rotation of a cam to a reciprocating plunger via a tappet and a retainer, a diametric force acting on the plunger is reduced. The pump includes the retainer disposed on the plunger and a return spring exerting an urging force on the retainer in a direction of the tappet. A clearance between a plunger leading end and a tappet bottom surface opposed thereto is set to be greater than a clearance between a retainer bottom surface and the tappet bottom surface opposed thereto, and a clearance between a retainer inside diameter section and a plunger peripheral surface section opposed thereto is set to be greater than a clearance between a retainer outside diameter section and a tappet inner wall opposed thereto.

摘要： It is an object of the present invention to accurately position a cylinder of a high-pressure fuel pump with respect to an attachment fitting hole provided in an engine block of an internal combustion engine in mounting the pump on the engine block.The high-pressure fuel pump of the invention is provided with a holder including: an outer cylindrical surface portion fitted to a high-pressure fuel pump attachment fitting hole installed on an engine block of the internal combustion engine; and a cylindrical fitting portion fitted to an outer circumference of the cylinder of the pump. The holder is configured such that the outer cylindrical surface portion and the cylindrical fitting portion are formed in a single piece resulting from machining one and the same member. Such a configuration can achieve the above-mentioned object. The central axis of an insertion hole of the piston plunger installed in the cylinder easily provides coaxiality with respect to the central axis of the attachment fitting hole installed in the engine block of the internal combustion engine. Biting and wear between the cylinder and the piston plunger, which are caused by the side force applied to the piston plunger by a drive mechanism, can be reduced.
摘要翻译：本发明的目的在于，将设置在内燃机的发动机缸体中的安装配合孔相对于高压燃料泵的缸体精确地定位在发动机缸体上。本发明的高压燃油泵设置有一个保持器，该保持器包括：一个安装在内燃机的发动机缸体上的高压燃油泵附件安装孔的外圆筒表面部分; 以及装配到所述泵的所述气缸的外周的圆筒形配合部。保持器构造成使得外圆筒形表面部分和圆柱形装配部分形成为通过加工同一构件而形成的单件。这样的结构可以实现上述目的。安装在气缸中的活塞柱塞的插入孔的中心轴容易地提供相对于安装在内燃机的发动机缸体中的安装配件孔的中心轴的同轴度。可以减少由驱动机构施加到活塞柱塞的侧向力引起的气缸和活塞柱塞之间的咬合和磨损。

摘要： The present invention eliminates a valve holder and accommodates a valve guide in a small space provided between a valve seat and a peripheral surface part of a pressure chamber to reduce the size of a pump. The valve guide guides a stroke of the valve and is provided inside the valve seat. The valve includes an annular abutting surface that abuts a valve seat formed in a valve housing to shut off a fuel intake passage and a bottomed cylindrical part is provided at an inner peripheral part of the annular abutting surface. The bottomed cylindrical part is inserted into a fuel introduction hole formed in the valve housing inside the valve seat. A member having a cylindrical surface part that supports a reciprocating motion of the valve, is fixed to the valve housing, face-to-face with an inner peripheral part of the bottomed cylindrical part.
