High-pressure fuel pump for fuel injection device of internal-combustion engine, has spring plate rotatably provided around predetermined limited angle range around longitudinal axis, and coupled unrotatably with supporting element

摘要

The pump has a pump piston (20) driven in a stroke movement via a tappet mechanism (18). A roller (54) rolls on a cam (16). The tappet mechanism is loaded to the cam by a compression spring element (58). The compression spring element is unrotatably supported around a longitudinal axis (19) of the tappet mechanism indirectly at a housing part (24) and at a spring plate (60). The spring plate is rotatably provided around a predetermined limited angle range around the longitudinal axis of the tappet mechanism, and is coupled unrotatably with a supporting element (52) over the angle range.
