Abstract

A pneumatic controller for an injection pump of an internal combustion engine which varies the quantity of injected fuel and which includes a pneumatic actuating device acting on the quantity adjusting member of the injection pump which in the presence of a vacuum displaces the quantity adjusting member in the direction toward smaller injected quantities, and a force storage device also acting on the quantity adjusting member; a drive lever actuatable at will is provided which is operatively connected with the controller for selectively varying the torque of the engine; additional means are also provided in the controller which produce a vacuum corresponding to the deflection of the drive lever from its normal rest position while a connection exists between the additional means and the pneumatic actuating device to transmit to the latter the vacuum produced in the former.
