is supported against a spring plate 73 .. So far, a pin 74 fastened in the housing part 1 is guided displaceably * A lever 75 acts on the spring plate 73 _; mounted on an arbitrarily rotatable adjustment shaft 76 _'t In the drawn. position of the governor which is Druckstüok 1 \ to a seated in the housing part 1 stop screw 77 at.

The axial forces aez Ji ¹ Ij ehkraftreglers acting on the pump end Ils 5 are absorbed by a pin 78 at the upper end of the iVeile 2 ρ on which the collar of the pump nwe Ho 5 is supported,

In Fig.-, 1 and 5, the cam 7 and the Fiuapenko3.beη 8 in the position marked _y ^{dis> ä3m} beginning of 8fi.ughu.0es 3ind corresponds, In Figo 4, the Pumpsnwslla with its control grooves 25 and 26 in presented the corresponding Saiighubbeginn the position * in contrast, in Figo 1 for clarity the Sa'jklöcher 30 and the branch holes 32 in a position drawn _s they only dignitaries taking the pump piston about after covering the half suction stroke. Also, the cross bore, 24 and control grooves 25 and 26 in the pump shaft are shown rotated in Fig. 3 in relation to reality for reasons of a better overview in the sectional plane. From Figo 3 it can be seen, that the control with 26 in contrast to the control groove 2? obliquely to the axis of the pump shaft 5 runs

The pump described works as follows; . ■

During the suction stroke of the pistons 9, the fuel flows through the connection nipple 28 _f the bores 3O ₉ 32 _? the channels 34 and 35 and the control boresn-36 in the pump working spaces * During the subsequent pressure stroke, the channels 34 are in connection with the bores 40 (Pig «2) ¹ . The pump pistons therefore deliver through the pressure valve 20 and the space 42 to the distributor bore 43 and via one of the four outlet channels 44. the associated outlet nipple 45 *
