Patent ID: 8099916

Claim:
A venting system for windows, comprising: a) at least one window, wherein the window further includes at least an inner pane and an outer pane, and wherein the panes define an air space therebetween; b) at least first and second unidirectional valves for allowing moisture-laden air to flow out of the air space formed between the panes, wherein a portion of each valve is adapted to be inserted through an aperture formed in the window pane and into the air space, and wherein each valve further includes: i) an elongated body having an interior passage formed lengthwise therein, having a circular plate attached to one end of said body and a trough formed integrally with the other end of said body and defining a U-shaped opening substantially perpendicular to the circular plate; ii) at least one flexible plate, a portion of said plate in pivotal contact with the elongated body, and an end of said plate extending into the trough; wherein each of the flexible plate moves in response to changes in fluid pressure within the air space formed between the panes of the window, wherein the movement of each flexible plate opens or closes the respective interior passage, the first unidirectional valve is inserted in a lower portion of the inner pane such that the respective flexible plate is facing in an upward direction, and the second unidirectional valve is inserted in an upper portion of the outer pane such that the resilient plate is facing in a downward direction, and wherein the placement of the first and second unidirectional valves in the inner and outer panes permits airflow through the air space.
