Patent ID: 8230957

Claim:
A work machine, comprising: a housing, a source of pressurized air, an engine, a baffle positioned within the housing between the source of pressurized air and the engine so as to partition an interior region of the housing into a cooling compartment in which the source of pressurized air is positioned and an engine compartment in which the engine is positioned, wherein the baffle flares laterally outwardly relative to an axis as the baffle extends along the axis away from the source of pressurized air toward the engine compartment so as to divert air flow from the source of pressurized air laterally outwardly toward a peripheral edge of the baffle to create a flow-inducing region, in a peripheral space between the peripheral edge and the housing and in fluid communication with the engine compartment, that ventilates the engine compartment, the baffle including a main body in the form of a frusto-pyramidal section and a lip, the main body including a basal, first end and a second end opposite to and narrower than the first end, the lip flared outwardly from the second end of the main body to the peripheral edge.
