  • Patent number: 4549474
    Abstract: A floor outlet for an air conditioner has a grill which is formed by ring elements whose radial connecting ribs are inclined to impart a vortex flow to the emerging air. A central baffle body is constituted by a disc and a multiplicity of angularly equispaced radially extending blades twisted out of the plane of the disc and projecting therefrom.

  • Patent number: 4520844
    Abstract: The invention concerns a regulator valve for stabilizing volume flow, especially in ventilation systems, with an adjustment flap (4) which is pivotable mounted in a flow conduit (2) and can be adjusted by a variable adjusting motor (12) and with a measuring probe (14) located in the flow conduit (1 resp. 2). In order that a reliable regulation and stabilization of the volume flow is possible independently of the arrangement and of the configuration of the conduit system upstream from the regulator valve, a turbulence grate (6) should be located upstream from the adjustment flap (4).

  • Patent number: 4508022
    Abstract: The invention concerns a ceiling air outlet, especially for air-conditioned areas, with a housing which can be connected to a supply air line and has a separating wall, two flow paths and an outlet grate, whereby an adjustment flap is located in at least one of the flow paths. In order to maintain a stable flow of areal air under a variable amount of supply air furnished by the air-conditioning system, the separating wall is positioned essentially parallel to the outlet grate and has at least one opening which can be closed by the adjustment flap. A series of jet openings or jet slits directed toward the outlet grate are located in the separating wall at least in the area of the free edge of the adjustment flap.

  • Patent number: 4488575
    Abstract: The invention concerns a volume flow regulator for ventilation systems with a conduit section (1) in which a regulating part (3) is pivotably mounted about an axle (2) which bisects the conduit cross section, whereby the regulating part (3) has a basically even surface on its leading side and a length which corresponds to the conduit height.In order to reduce the noises produced by the volume flow regulator itself, the regulating part (3) has a semicircular section in a plane vertical to its pivot axle (2), whereby the section radius corresponds to one half the conduit height. In a rectangular conduit section the regulating part (3) is a semicylinder whose curved contour fits against a conduit wall with a slight amount of play in all regulating positions. The regulating part can be balanced in various ways. In addition, a diffuser (24, 27) can be connected in after it which also functions as a sound absorber.

  • Patent number: 4259898
    Abstract: A ceiling air outlet for a climate control system having a first outflow channel for receiving air and delivering it in a substantially horizontal direction from an outlet surface, a second outflow channel for receiving air and delivering it in a substantially vertically downward direction from the outlet surface, the first and second outflow channels having at their inlet ends a common air supply channel, and a damper mounted in the connecting region of the first and second overflow channels and the supply channel for automatically regulating the air flow into one of the outflow channels in response to the volume flow of air, the damper closing the outflow channel in response to lower volume flow of air and opening the outflow channel in response to higher volume flow of air, whereby the speed of the air delivered from the outlet surface is maintained at an adequate level.

  • Patent number: 4175583
    Abstract: A regulator valve for maintaining a constant volumetric flow comprising a flap installed within a flow duct and pivotable from an open position to a closed position against the action of a biasing force, a bellows whose internal volume is in communication via an opening in the flap with the upstream side of the flap, the bellows further being joined to the downstream side of the flap and supported in the duct.
