TAPPET FOR ACTING ON A PUMP PISTON OF A HIGH-PRESSURE FUEL PUMP

The disclosure relates to a tappet for acting on a pump piston of a high-pressure fuel pump of an internal combustion engine. The tappet includes a tubular housing, and at the upper annular end face of the tubular housing, two surfaces which are indented relative to the outer casing of the housing and comprise a pin that supports a cam roller, lie diametrically opposite each other. An upper end face of a transverse beam lies against axial inner end faces of the two surfaces. A transverse beam lower end face, which faces a lower annular end face of the housing, is provided with a pin, which protrudes from the housing and is surrounded by a spring plate supported against the inner casing of the housing. A sleeve-like inner collar of the spring plate guides the unstepped pin.
