Component for fuel high pressure pump of quality or quantity- controlled combustion engine, has pump piston exhibiting equal diameter continuously and provided with separate drive plate within sleeve that is protruded from bottom of plate

摘要

#CMT# #/CMT# The component (1) has a plunger (3) connected to a pump piston (2), which rests against a lower surface (6) of a separate bridge piece (5). An outer jacket of the piston is placed close to the lower surface by a pot-shape spring plate. A sleeve is protruded from bottom of the plate. The sleeve passes a gorget lying close to the lower surface of the bridge piece. A lower surface of the gorget forms an arrangement for a pump piston return spring. The piston exhibits same diameter continuously, and is provided with a separate drive plate (20) within the sleeve. #CMT# : #/CMT# The bridge piece, the pot-shape spring plate and the drive plate are formed as a sheet metal part using punching or stamping technology. #CMT#USE : #/CMT# Component for a fuel high pressure pump of a quality or quantity- controlled combustion engine. Can also be used for a valve train. #CMT#ADVANTAGE : #/CMT# The pot-shape spring plate, the bridge piece and the drive plate are formed as the sheet metal part using the punching or stamping technology, so that the component can be manufactured in light-weight and inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a component for a fuel high pressure pump of a quality or quantity- controlled combustion engine. 1 : Component 2 : Pump piston 3 : Plunger 5 : Separate bridge piece 6 : Lower surface of separate bridge piece 20 : Separate drive plate.
