AXIAL FLOW COOLING AIR FILTER SYSTEM

摘要

A filter assembly for filtering the cooling air entering the starter housing of a small aircooled internal combustion engine. The assembly includes a plurality of upstanding brackets attached to the perforated face of the starter housing. The brackets include hook-shaped upstanding ends. A foam filter medium includes a plurality of slits formed therein, which correspond to the brackets. The filter is placed over the brackets and against the face of the housing such that the brackets receive the respective slits. A retaining ring is snapped into the hook-shaped ends for retaining the filter and for biasing the filter against the face of the starter housing to form a tight seal therebetween.
