Abstract
Abstract An air intake vent (20) for the cowl opening (24) of an armored vehicle includes a front armor plate (26) extending upwardly from the cowl (22) forward of the opening and a holder (30) for mounting an air filter (32) over the cowl opening, and the vent also includes a flanged cover (34) that prevents projectiles from passing through the cowl opening while still permitting air to enter the vehicle. A front flange (36) of the cover extends downwardly in front of the front armor plate preferably with an inclined orientation so as to provide good deflection of projectiles away from the cowl opening. A pair of side armor plates (38) extend upwardly from the cowl on opposite lateral sides of the opening thereof and side flanges (44) on the cover extend downwardly outboard therefrom in a spaced relationship. The holder for the air filter includes an L-shaped rear mount (30) that positions the rear extremity (45) of a mounted filter such that the front and side extremities (46, 47) thereof are respectively positioned by the front and side armor plates on the cowl. Supports (48, 52) for the cover are mounted on the front and side armor plates and have a construction that permits removal and mounting of an air filter for servicing or replacement.
