| 摘要 |
A hydraulic control device for fuel injection pumps of internal combustion engines, having a control conduit that branches off from a high-pressure chamber, such as a pump work chamber, and acts in a control chamber upon a control face of a stepped piston for hydraulically stepping down the volume, the piston working face having the smaller diameter defining a closed work chamber, which has an outflow controllable by a valve; a functional face on the movable valve element is acted upon from the work chamber and determines the time/cross section control.
