<p>A device for cleaning induction air for a combustion engine used as a power source in a lawn mower of the kind which is supported by means of a cushion of air is disclosed. The present device adequately cleans induction air for the motor while avoiding the use of the hose and comprises a cylindrical chamber with tangential air inlet openings, an induction tube extending co-axially into the chamber, and a filter element. The chamber has an outlet opening remote from the inlet openings and from the entrance to said induction tube, this outlet opening is in communication through ducting with a position adjacent an air inlet port in the housing of the mower. Thus, when the mower is in operation air enters through said tangential air inlet openings and makes a rotary motion within the chamber so that the air is partially cleaned as in a cyclone separator. A portion of this partially cleaned air passes through the induction tube and the filter element to the engine. The particleladen air passes from the chamber through the outlet opening and provides the air cushion for the lawn mower.</p> |
