Abstract

In a fuel injection pump, fuel pressurized by a feed pump is supplied to an accommodation chamber via a communication path having an orifice. An end of the communication chamber on a side of the accommodation chamber is positioned to face an axial end of a minute space between sliding contact portions of a cam and a bush when the cam is at a given angular position. The fuel fed from the feed pump is injected from the end of the communication path axially deep into the minute space between the sliding contact portions so that oil film for lubrication is formed on the sliding contact portions, resulting in suppressing frictional seizure of the sliding contact portions.
