摘要： A fuel injection pump has an injection adjusting piston (10) which adjusts the injection beginning. The injection adjusting piston (10) is exposed during its operation to tilting moments because of its eccentric articulation to a part (3) of the cam drive of a fuel injection pump designed as a distributor injection pump. In addition, the injection adjusting piston (10) is exposed to further forces which derive from a radial hydraulic medium supply (55) at the side of the injection adjusting piston (10) opposite to its articulated joint. Together with the tilting moment forces, these further forces exercise high unilateral pressing forces in the radial direction on the injection adjusting piston. By providing a second pressure field (57), said forces which act on the injection adjusting piston (10) are compensated for and the injection adjusting piston (10) is subjected to a substantially reduced radial stress.

摘要： Disclosed is a fuel injection pump provided with a timing device piston (16) for timing beginning of injection and designed as a slaved piston for a slide valve (28) located therein. Said piston encompasses a working chamber (20) on one of its sides and is driven by pressure in said working chamber in opposition to the force of a return spring (23) and connected to a substantially fixed part of fuel injection pump cam drive. In order to avoid the effects of pressure backlash arising from kickback on the slide valve (28) and its setting, the inlet cross-section of connecting conduit is designed as an extended elongated cross-section which extends in the sliding direction of said slide valve. This enables trouble-free setting of the slide valve (28) and more precise vibration-free setting of timing device piston (16) and beginning of injection.

摘要： Proposed is a fuel-injection pump fitted with a piston (16) which controls the start of injection and which is designed as a follow-up piston to a control piston (28) located inside it. Located on one side of the piston is the working space (20), the pressure in which acts through the piston on a restoring spring (23), the piston being connected to an essentially stationary part of a cam drive in the fuel-injection pump. In order to avoid feedback effects of the working space (20) on the position of the control piston (28) and its adjustment, the motion of the control piston is efficiently damped by a separate pin (46) which extends into a dead-end bore (48).
