The screen assembly may generally include a screen defining a plurality of screen openings for receiving an airflow therethrough. In addition, the screen may define a flap opening. The screen assembly may also include a flap pivotally coupled to the screen at the flap opening. The flap may be configured to be moved to a closed position when the airflow through the screen is in a first direction and to an opened position when the airflow through the screen is in a second direction. ## Claims ### Claim 1 A screen assembly for a work vehicle, the screen assembly comprising: a screen defining a plurality of screen openings for receiving an airflow therethrough, the screen further defining a flap opening; a flap pivotally coupled to the screen at the flap opening, the flap being configured to be moved to a closed position when the airflow through the screen is in a first direction and to an opened position when the airflow through the screen is in a second direction, wherein the second direction is opposite the first direction, ### Claim 2 (depends on 1) The screen assembly of claim 1, further comprising a hinge coupled between the screen and the flap at a top edge of the flap opening. ### Claim 3 (depends on 2) The screen assembly of claim 2, wherein the flap is configured to overlap at least a portion of the screen around a perimeter of the flap opening when the flap is in the closed position. ### Claim 4 (depends on 1) The screen assembly of claim 1, further comprising a biasing mechanism coupled to the flap, the biasing mechanism being configured to bias the flap into the closed position. ### Claim 5 (depends on 1) The screen assembly of claim 1, wherein the screen is configured as a front screen or an auxiliary screen of the work vehicle. ### Claim 6 A work vehicle, comprising: a hood enclosure extending between a forward end and an aft end; a front screen disposed at the forward end of the hood enclosure; a heat exchanger positioned behind the front screen; a fan configured to generate an airflow in both a first direction, wherein air is drawn into the hood enclosure through the front screen and flows through the heat exchanger, and a second direction, wherein air is directed through the heat exchanger and out of the hood enclosure through the front screen; and a flap movable relative to the front screen, the flap configured to be in a closed position when the airflow is directed in the first direction and an opened position when the airflow is directed in the second direction. ### Claim 7 (depends on 6) The work vehicle of claim 6, wherein the front screen defines a flap opening, the flap being pivotally coupled to the front screen at the flap opening. ### Claim 8 (depends on 7) The work vehicle of claim 7, further comprising a hinge coupled between the front screen and the flap at a top edge of the flap opening. ### Claim 9 (depends on 7) The work vehicle of claim 7, wherein the flap is configured to overlap at least a portion of the front screen around a perimeter of the flap opening when the flap is in the closed position. ### Claim 10 (depends on 6) The work vehicle of claim 6, further comprising a biasing mechanism coupled to the flap, the biasing mechanism being configured to bias the flap into the closed position. ### Claim 11 (depends on 6) The work vehicle of claim 6, further comprising an auxiliary screen spaced apart from the front screen in the direction of the aft end of the hood enclosure, ### Claim 12 (depends on 11) The work vehicle of claim 11, further comprising an auxiliary flap movable relative to the auxiliary screen, the auxiliary flap configured to be in an opened position when the airflow is directed in the first direction and a closed position when the airflow is directed in the second direction. ### Claim 13 A work vehicle, comprising: a hood enclosure extending between a forward end and an aft end; a screen assembly coupled to the hood enclosure, the screen assembly including a screen defining a plurality of screen openings for receiving an airflow therethrough and a flap movable relative to the screen; and a fan configured to generate an airflow in both a first direction, wherein air is drawn into the hood enclosure through the screen and a second direction, wherein air is expelled from the hood enclosure through the screen, wherein the flap is configured to be in a closed position when the airflow is directed through the screen in the first direction and an opened position when the airflow is directed through the screen in the second direction. ### Claim 14 (depends on 13) The work vehicle of claim 13, wherein the screen assembly is disposed at the forward end of the hood enclosure. ### Claim 15 (depends on 13) The work vehicle of claim 13, wherein the screen assembly is disposed aft of the forward end of the hood enclosure. ### Claim 16 (depends on 13) The work vehicle of claim 13, wherein the screen defines a flap opening, the flap being pivotally coupled to the screen at the flop opening. ### Claim 17 (depends on 16) The work vehicle of claim 16, further comprising a hinge coupled between the front screen and the flap at a top edge of the flap opening. ### Claim 18 (depends on 13) The work vehicle of claim 13, wherein the flap is configured to overlap at least a portion of the front screen around a perimeter of the flap opening when the flap is in the closed position.
