摘要： PURPOSE: To render starting and finish of high-pressure injection consistent with and suitable for characteristics of an internal combustion engine by forming an oval-shaped control opening for slight pre-discharge effect at starting of injection and rapid relief control at finish of the injection. CONSTITUTION: A fuel is supplied into a pump working chamber 11 via a control opening 13 radially extending in a wall of a cylinder bore 3. Further, the control opening 13 cooperates with an oblique control edge 17 on a pump piston 1 for finishing fuel injection. Particularly, a profile 25 of an outlet face of the radial control opening is shaped into a uniform oval within a wall of a cylinder sleeve 7. As a consequence, gentle pressure increase at starting of high pressure discharge and rapid pressure relief of the pump working chamber 11 at finish of high-pressure discharge can be realized via the oval shape of the control opening 13.

摘要： PURPOSE: To obtain a large full regulating distance by performing a transfer to a second oblique control edge toward a pump working chamber in a plunger longitudinal direction via a step part and making space between the second oblique control edge and a second end face side control edge smaller than a diameter of a control opening. CONSTITUTION: A pump plunger 1 can be rotated and has a control notch 22 which is formed by two oblique grooves on the peripheral surface and cooperates with a control opening 11. A transfer part between a first oblique control edge 26 and a second oblique control edge 30 of each different gradient is formed by a step part 32 extending in a plunger longitudinal direction. This step part 32 is arranged at a height of the transfer part between control edges 14, 18 on first and second end face sides, that is, a location matched with the transfer part from viewpoint of the plunger longitudinal direction. Space between the first oblique control edge 26 and the first end face side control edge 14 is made larger than the length of the control opening 11, that is, the diameter. Space between the second oblique control edge 30 and the second end face side control edge 18 is made smaller than the diameter of the control opening 11.

摘要： PURPOSE: To obtain a reverse rotation-preventing effect of an internal combustion engine at a high rotation frequency and high recoil preventability of a tappet with rollers by extending a cam down-face in the shape of a substantially convex circulate arc. CONSTITUTION: A peripheral surface of a camshaft has at least one cam 3, and a cam track 5 of the cam 3 is divided into four sections. A first section is formed by a basic circle 9. Following the base circle 9, a second section is provided in the form of a tangentially linear cam up-face 11. The second section moves towards a vertex circle 13 drawn by a vertex of a cam lobe that defines a third section. A fourth section that connects the vertex circle 13 and the base circle 9 is formed as a cam down-face 15. In this structure, particularly the cam down-face 15 extends in the shape of a substantially convex circular arc. Therefore, recoil preventability of a tappet 7 with rollers can be improved.

摘要： PURPOSE: To achieve cost-effective manufacturing and mounting by forming a cylindrical part on an entraining pin for varying the travel position of an annular slide and press-fitting the part in a bore of an adjustable shaft. CONSTITUTION: To operate an annular slide 17 axially on a pump piston 7, the slide 17 is provided with a recess 43 at the opposite side of a web 19, and an entraining pin 45 which is an eccentric pin is engaged at a head piece 47 thereof. A cylindrical part 49 of the entraining pin 45 is formed by a slide fit seating section 61 having a diameter slightly less than a press fit seating section 57 starting from an end face 35. The slide fit seating section 61 is adjacent to a shaft portion 63 arranged eccentrically with respect to a neck portion 65, and concentrically coupled with the head piece 47. The entraining pin 45 is press-fitted into a radial bore 51 which is slightly less than the press fit seating section 57 of an adjustable shaft 53. In this case, it is possible to adjust the precise rotational position of the entraining pin i.e., the eccentric position thereof, hence the travel starting position of the annular slide 17.

摘要： PURPOSE: To provide a fuel injection pump for an internal combustion engine which is capable of effecting pre-injection and main injection suitably, and can be manufactured at inexpensive cost. CONSTITUTION: A pump piston enclosing a pump work chamber 5, reciprocates in a cylinder bush 2 inserted into a pump housing 1. The pump piston has a control recess on its jacket face that communicates with the pump work chamber through a conduit 39. The recess has an oblique groove 19 extending at a predetermined angle from the axis of the pump piston in the jacket face thereof and forming control edges 21, 22. An annular slide 13 is axially displaceable on the pump piston and includes two diametrically opposed control bores 41. To interrupt the high pressure pumping to provide a pre-injection and a main injection, pockets 25-27 are machined into the jacket face of the pump piston. These pockets cooperate with pockets 42 machined in the annular slide and with a control edge 45 formed by the lower edge of the annular slide.

摘要： PURPOSE: To reduce the manufacturing and assembling costs by allowing a slide shoe to slide along a flat slide passage arranged on a notched wall, and preventing a control slider from turning. CONSTITUTION: A control slider 5 is provided with a slide shoe 19 extending in the direction of the working stroke on a side toward a notched wall 22. The slide shoe 19 slides along a flat slide passage 23 arranged on the notched wall 22. The control slider 55 is prevented from turning.

摘要： PURPOSE: To provide high stability by using a simple and low-cost manufacturing method of the barrel of an fuel injection pump for an internal combustion engine. CONSTITUTION: A control sleeve 5 is ensured so as to be prevented from being twisted in the sliding passage 23 of a recessed part 4 with at least one integrally-formed safety protrusion 19, and the recessed part formed in a barrel 2 to accommodate the control sleeve is manufactured by the plastic working.
