Abstract
A fuel injection apparatus is proposed for internal combustion engines with distributor and apportionment valves, which serves to apportion a quantity of fuel proportional to the induced air quantity. The distributor and apportionment valves of the fuel injection apparatus comprise a slide valve which is displaceable opposite a slotted bushing fixed in the valve housing and equipped with slots, in order to effect the variation of the current flow area of the apportionment valves. A control sleeve is interposed between the slotted bushing and the control slide and includes a portion which partially covers the control slots in the bushing to provide for fine control of the control slots in the bushing.
