Abstract

In fuel injection pumps the pump chamber is discharged at the end of injection by the opening of an overflow aperture. Due to these overflow impacts cavitation occurs in the housing of the injection pump which can lead to detached metal particles which in turn cause damage to the injection system. According to the invention it is proposed to arrange an acutely angled baffle plate inside the discharge chamber whose acute opening angle is turned towards the overflow aperture. The invention can be used in the case of injection pumps, in particular in-line injection pumps. <IMAGE>
