Engine air intake screen assembly

Abstract From the Canadian patent

An engine intake screen assembly as provided. A rotatable screen has a continuous peripheral skirt which telescopes with an upstanding housing ring-like flange so as to create a serpentine entry path for grass and other foreign matter trying to enter at the seam between the screen and the inlet. Entry can be further restricted through the use of a radially outwardly directed ring extension on the screen and/or a guard ring member. These parts can combine to form a trap pocket and/or to increase the serpentine nature of the entry path. In one version the grass will form its own seal in the trap.
