ABSTRACT:
A fuel injection pump, the volume adjustment member of which has a limiter of its play in the form of an adjustable device, which is movable in accordance with the displacement of a control piston in response to a contour provided in the control piston. The displacement of the first control piston occurs in accordance with the pressure of the air supplied to the combustion chambers of the internal combustion engine, and this in turn is controlled with the aid of a pressure element. The pressure element actuates a control piston, with the aid of which a control pressure is created which actuates the first control piston. The control pressure, at the same time, acts on the pressure element by way of the second control piston in the form of return pressure. In a state of equilibrium the control pressure circuit is separated from the pressure source.
