Problems solved by technology

Furthermore, since the membrane member is typically positioned upstream from the plate member, whereby air pressure tends to force portions of the membrane member against the plate member, the frictional forces associated with moving the membrane member and wear on the membrane member are further increased

Abstract

An air passage flow control device according to the invention includes a plate member having at least one aperture through which air may pass, the degree to which the aperture is exposed being controlled by the positioning of a film member across at least a portion of the aperture. The positioning of the film member relative to the aperture is controlled by rolling and unrolling a portion of the film member on a rotating member that may be selectively moved back and forth across the aperture. By rolling and unrolling the film member to control the opening of the aperture, the present invention avoids relative lateral movement of those portions of the film member that are in contact with the plate member, thereby reducing the frictional forces. Further, the rotating member is configured to reduce the collection of particulate matter on the rotating member and the film member.

Description

technical field [0001] The present invention relates to an air passage opening / closing device suitable for use in various air handling or conditioning devices including, for example, automotive air conditioning systems. Background technique [0002] A conventional air passage opening / closing device may include a housing and a plate member provided in the housing. The plate member may include one or more apertures through which air or other fluid flows, and the membrane member is disposed adjacent the plate member and may be configured to at least partially block the apertures. The membrane member may also comprise at least one opening through which air may pass, and both ends of the membrane member may be connected to the axis of rotation in such a manner that rotation of the one or more axes will change the relative position of the membrane member to the plate member and the apertures provided therein. Structure. [0003] In this way, one or more openings provided in the ...
