ABSTRACT:
An improved vent cap is disclosed comprising a body having a top wall, bottom wall and a closed side wall which together define an interior chamber. A tubular threaded member extends outwardly from the bottom wall of the body for attaching the vent cap to a desired machine while an annular filter is entrapped between the top wall and bottom wall at a position spaced inwardly from the side wall. Thus, one side of the filter is open to the interior chamber while an annular subchamber is formed between the other side of the air filter and the body side wall. At least one opening is formed through the bottom wall to the annular subchamber.
