ABSTRACT:
A pump
ozzle 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
ozzle 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
ozzle 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
ozzle unit this drive assembly unit remains joined to the pump
ozzle unit by the holder mechanism.
