録請求の範囲第１項記載の燃料噴射ポンプ[Claims for Utility Model Registration] 1. A fuel injection pump for a multi-cylinder internal combustion engine, comprising a plunger that performs rotation and reciprocating stroke motion, and a rotary cam disc that drives the plunger, the cam disc being With the rotational movement, the front cam moves over the fixed roller, and the roller is compressed by a plurality of pressure springs extending axially with respect to the plunger, and these pressure springs are equally spaced from the plunger axis. is supported on the one hand by the pump housing and, on the other hand, by an immovable yoke arranged concentrically with respect to the cam disc and supported by the cam disc, which surrounds the plunger and supports the plunger. A control slide is provided which slides over a segment and which can be actuated by means of an adjusting member to vary the fuel injection quantity, the cam disk 12
In order to press the yoke 24, three pressure springs 25, 26, 27 are distributed in the circumferential direction of the ribbon-shaped yoke 24. The third pressure spring 27 is symmetrically offset by an equal angle α greater than 90° in each case with respect to the third pressure spring 27, so that the spring force of the third pressure spring 27 is
, 26 multiplied by the cosine of the respective angles α. 2. The fuel injection pump according to claim 1, wherein the angle α is smaller than 120°.
