A fuel injection pump in which a pump work chamber can be connected with a fuel withdrawal chamber, which is controlled by a deflecting piston. The deflecting piston is loaded by the pressure of the pump work chamber and is adjustable counter to a restoring force, this restoring force being modified

A fuel injection pump in which a pump work chamber can be connected with a fuel withdrawal chamber, which is controlled by a deflecting piston. The deflecting piston is loaded by the pressure of the pump work chamber and is adjustable counter to a restoring force, this restoring force being modified with pressure fluid in accordance with rpm.

A fuel injection pump comprising at least one pump piston and a pump work chamber defined by said piston, a withdrawal chamber connected with said work chamber in order to influence a course of fuel injection at a fuel injection line supplied by said work chamber, said fuel withdrawal chamber being

A fuel injection pump comprising at least one pump piston and a pump work chamber defined by said piston, a withdrawal chamber connected with said work chamber in order to influence a course of fuel injection at a fuel injection line supplied by said work chamber, said fuel withdrawal chamber being defined by a first movable wall which on the side remote from said fuel withdrawal chamber is loaded by a restoring means comprising a restoring spring towards an abutment of said first movable wall, said restoring means being provided in a restoring chamber, and simultaneously acting upon a second movable wall defining said restoring chamber, a variable pressure medium, said second movable wall being subjected to a variable pressure of said variable pressure medium, the position of said second movable wall relative to said abutment of said first movable wall is varied over the entire operating range of the fuel injection pump in counterbalance of forces resulting from said restoring sring and said varying pressure of said variable pressure medium and thereby controlling the restoring force of said restoring means acting upon said first movable wall.
