Abstract: A fluid deflecting assembly for deflecting a fluid medium in any desired direction, particularly suited for use in an air conditioner, which has a nozzle for issuing a main stream of fluid as the fluid passes therethrough, a guide wall at a position downstream of the nozzle and having substantially a diverging shape in a direction downstream with respect to the direction of flow of the main stream and opening outwardly in a direction away from the nozzle, and a control device for controlling the mode of flow of the fluid at a position upstream of the nozzle. The nozzle has a relatively small thickness in the direction of flow of the fluid therethrough and is so shaped as to constrict the flow of the fluid as the latter passes therethrough.

Abstract: An air conditioner including an air intake, a blower for drawing air into the air conditioner through the air intake, a heat exchanger in the path of the air, and an air exit structure in the path of the air. The air exit structure is a plate-like sheet of rigid material having an aperture therein forming a nozzle for issuing a main stream of air as the air passes therethrough. A control chamber downstream of the nozzle develops a pressure differential in the main stream of air flowing from the nozzle as it flows between a pair of spaced opposed diverging walls to control the direction of flow of the stream. The pressure differential is developed by closing control apertures in the chamber by interceptors over the control apertures.

Abstract: A fluid diverting assembly is constituted by a structural body having a nozzle from which a main stream of fluid is issued as the fluid passes therethrough, a pair of opposed control chambers positioned adjacent the nozzle and on respective lateral sides of the stream of fluid, a pair of side walls outwardly diverging in a direction downstream of the nozzle with respect to the direction of flow of the main fluid stream, and control apertures respectively communicated to the control chambers. An interceptor mechanism is provided for alternately adjustably closing any one of the control apertures for deflecting the direction of flow of the main fluid stream issued by the nozzle.
