ければならない。BACKGROUND OF THE INVENTION Such dispensing injection pumps are generally known in the prior art. This known distributed injection pump is used to selectively supply fuel under pressure to an injection nozzle of a combustion engine. On the basis of the pressure present in the distribution channel, a pressure field (Druckfeld) is created for each injection, which produces a circulating lateral force in connection with the rotation of the distribution axis. This displaces the distribution axis. Each opposing force is formed by a hydrodynamic sliding bearing, which sliding bearing is formed on the side of the distribution shaft opposite the distribution groove. The lubrication supply is affected by the play between the bearing and the distribution shaft, since this sliding bearing is, according to the prior art, caused by a leakage flow between the distribution shaft and the bearing of the distribution shaft. In all cases, the leakage flow is such that, even under pulsating loads, there is sufficient lubricant flow between the distribution shaft and the bearing, on the one hand to ensure cooling and on the other hand a sufficient fluid cushion. Must be.

And a second section 26. The first section 24 of the lubricant groove extends from the end face of the distribution shaft 10 on the right side as viewed in the drawing to the return filling groove 28 and the second section of the lubricant groove.
Section 26 starts from the return filling groove 28 and
Of the bearing bush 12 extends to a location connected to the ring chamber 16. In this case, the cross section of the first section 24 of the lubricant groove is smaller than the cross section of the second section 26 of the lubricant groove. The basis is that if the width of the lubricant groove in the first section is assumed to be 0.5 mm, the width in the second section 26 can be assumed to be about 1.5 mm. Since the lubricant groove extends to the solenoid valve chamber, the flow required for cleaning and cooling is taken out in the area of the valve seat of the distribution-type injection pump,
High fluid efficiency is obtained.

FIG. 3 shows the pressure profile in a hydrodynamic sliding bearing, in which the distribution shaft 10 rotates in a bearing 14 which is filled with fuel acting as a lubricant. Occurs at the time. Based on the pressure governing the distribution groove 22, the distribution shaft 10
Lateral force acting on (indicated here by arrow F)
Is formed, and this lateral force circulates with the distribution shaft 10. This lateral force is counteracted by the pressure resulting from fuel being dammed in the narrowing bearing gap. Since the pressure distribution shown circulates together with the distribution axis, the lubricant groove is always located at the same position relative to the region where the negative pressure prevails.
