Title (EN) FUEL INJECTION PUMP
(FR) POMPE D'INJECTION DE CARBURANT
(JA) 燃料噴射ポンプ
Abstract:
(EN) A fuel injection pump (1) configured so as not cause blackening of fuel due to a lubricating oil mixed into the fuel after passing through a gap between a plunger (10) and a plunger barrel (11).  A fuel injection pump (1) is provided with a projecting guide section (12a) provided to a partition wall between a tappet chamber (16) below a plunger barrel (11) and a cam chamber (23) provided below the tappet chamber (16), and also with a roller tappet (20) inserted in the projecting guide section (12a) and connecting to the lower end of the plunger (10).  The roller tappet (20) is adapted to be able to reciprocate and slide along the projecting guide section (12a) of a pump case (12) in association with the rotational motion of a cam (21).  In the entire range of the sliding stroke of the roller tappet (20), the upper end of the roller tappet (20) always projects to the plunger barrel (11) side from the upper end surface of the projecting guide section (12a).
(FR) L'invention concerne une pompe d'injection de carburant (1) configurée de manière à ne pas entraîner de noircissement du carburant dû à une huile de graissage mélangée dans le carburant après avoir traversé un espace entre un piston (10) et un cylindre de piston (11). Une pompe d'injection de carburant (1) comporte une section de guidage en saillie (12a) se trouvant sur une paroi de séparation entre une chambre de poussoirs (16) sous un cylindre de piston (11) et une chambre de cames (23) se trouvant sous la chambre de poussoirs (16), et également un poussoir à galet (20) inséré dans la section de guidage en saillie (12a) et se reliant à l'extrémité inférieure du piston (10). Le poussoir à galet (20) est adapté à des fins de mouvement de va-et-vient et de coulissement le long de la section de guidage en saillie (12a) d'un corps de pompe (12) en association avec le mouvement de rotation d'une came (21). Dans l'ensemble de la course de coulissement du poussoir à galet (20), l'extrémité supérieure du poussoir à galet (20) fait toujours saillie du côté cylindre de piston (11) depuis la surface d'extrémité supérieure de la section de guidage en saillie (12a).
(JA)  潤滑油がプランジャ(10)とプランジャバレル(11)との隙間を通って燃料中に混入してしまい、燃料の黒色化が発生するという問題を解決する燃料噴射ポンプ(1)を提供する。プランジャバレル(11)の下方のタペット室(16)とタペット室(16)の下方に設けられたカム室(23)との間の隔壁に設けた張出しガイド部(12a)と、張出しガイド部(12a)に挿入され、プランジャ(10)の下端に接続するローラタペット(20)と、を有し、ローラタペット(20)は、カム(21)の回転運動に連動してポンプケース(12)の張出しガイド部(12a)に沿って往復摺動可能とされる燃料噴射ポンプ(1)であって、ローラタペット(20)の上端部は、摺動ストロークの全域において張出しガイド部(12a)の上端面からプランジャバレル(11)側に常に突出するものである。
