Abstract:
1. A fan shroud having an integrated aspirator for use in conjunction with a pre-cleaner, the pre-cleaner having an air intake, an aspirator port, and an air exhaust, and wherein a first end of the shroud is adapted for disposal proximal to a cooling module while a second end is adapted for disposal proximal to a fan, the fan shroud comprising: an upper section and a lower section mateably engaging one another at mating flanges so as to form an air passage between a fan and a cooling module of the vehicle; an aspirator portal in an upper surface of the shroud; an aspirator having an air intake and an air outlet, the aspirator being supported inside the shroud proximal to the fan with the air outlet facing the fan; and, a first end of an aspirator hose connected to the aspirator port of the pre-cleaner and passing through the aspirator portal and a second end of the aspirator hose connected to the air intake of the aspirator so that the aspirator hose passes generally through a mid-section of the shroud; whereby the vacuum necessary for proper aspiration of the pre-cleaner is accomplished by air movement, induced by the fan, between the air intake of the pre-cleaner and the aspirator via the aspirator port and the aspirator hose.
