摘要： A fuel injection pump has a work space which at a certain position of the pumping piston communicates with a tapping opening through which delivered fuel flows into an offtake space. The angular position at which the connection between the pumping space and the fuel offtake space is established, is adjustable in order to control the amount of injected fuel. The fuel offtake space is adjustable by means of a spring-biased piston. The position of the tapping opening to a distributing channel is adjustable by a movable supporting member communicating with a rotary distributor.

摘要： There is proposed herein that a push rod of a fuel injection pump embodied as a radial piston pump which push rod further has a groove in its base be arranged to positively secure a roller in a relatively fixed position. The push rod is slidably guided in a hollow cylindrical wall in a sleeve. An apertured hub which forms an end wall of the sleeve has a slit, into which a prong which offstands axially from a fastening ring secured to said hub is arranged to protrude into said push rod. A helical spring supported by the sleeve presses a piston of the pump against the inside of the base of the push rod.

摘要： A pump/nozzle unit having a piston injection pump and an injection nozzle which includes a pump piston that is driven via a drive tappet and is rotatable via a regulating sleeve. The regulating sleeve is inserted into a recess on the end face of the pump housing and is axially secured in its installed state by means of a guide bushing. The guide bushing comprises a guide part for the drive tappet and a flange radially protruding beyond the outer diameter of the tappet spring, the flange being secured on the pump housing by a holder mechanism. The forces exerted upon the pump/nozzle unit during operation are absorbed by a securing arrangement. The drive assembly unit, including the drive tappet, tappet spring, guide bushing and pump piston, which is held together by a loss-preventing device, can be mounted outside the pump/nozzle unit and removed as a unit for purposes of mounting and inspecting the regulating sleeve, and even in the demounted or disassembled state of the pump/nozzle unit this drive assembly unit remains joined to the pump/nozzle unit by the holder mechanism.
