<p>The present disclosure refers to a wear resistant insert element (100) configured to be inserted into a shaft (90) of a baffle body (80) for a plunger operated fuel pump (1) and a corresponding baffle body (80). Baffle bodies in plunger operated fuel pumps serve for absorbing the energy of a pressure wave generated during pumping operation of the fuel pump. However, conventional baffle bodies made of steel may be subjected to wear, in particular, in case they are used in a fuel pump operated with alternative fuels or low sulfur fuels having a low boiling point and/or a high content of water. The present disclosure suggests a wear resistant insert element (100) possibly made of ceramic and to be inserted into a baffle body (80) such that the end surface (92) of the baffle body (80) is configured to absorb the energy of the fuel pressure wave and, thus, resists wear.</p> |
