<p>An outlet port baffle 10 for an air or gas exhaust port comprises a cylindrical entrance section 20, a conical intermediate section 30 and a wall-like end section 50. The conical intermediate section 30 has two rows of apertures 42,44 extending over an arcuate segment of that section and has radially projecting, circumferential ridges 40a,40b,40c which are between and also help define the apertures 42,44. The air or gas enters the cylindrical section 20 and flows to the conical section 30 where it is redirected in a direction normal to its original flow and through the apertures 42,44. The outlet port baffle 10 may be utilized to redirect the air exhaust from a vacuum cleaner for example.</p> |
