Tappet body for supporting pump piston of high pressure pump designed as piston pump, has semi-spherical surface designed as contact area with camshaft

摘要

The tappet body (1) has a semi-spherical surface designed as a contact area with a camshaft (2). The single or multi-section tappet body is designed such that a rotation of the camshaft is converted into a translational movement of a pump piston during the operation of a high pressure pump. The semi-spherical surface of the tappet body has the shape of a hemisphere. An independent claim is also included for a high pressure pump for a fuel injection system.
