Device for controlling a volumetric rate of flow in a guide tube
First Claim
1. In a ventilation system having a conduit for transporting air and an adjustable flap valve pivotably mounted about an axis within said conduit for controlling the volumetric rate of flow of air through said conduit, a device for pivoting said flap valve for adjusting the volumetric rate of flow of air through said conduit in response to a sensed condition comprises:
- adjusting means mounted on said conduit, control means mounted on said adjusting means, said control means includes motor means responsive to a sensed condition sensed by a remote sensing means for driving a first driven means, said adjusting means includes a second driven means associated with said flap valve for pivoting said flap valve about said axis and coupling means for coupling said first driven means to said second driven means such that said flap valve is adjusted upon said sensing means sensing a change in said sensed condition wherein said first driven means comprises a geared disk which is seated on a shaft of the motor means, said second driven means comprises a geared wheel and said coupling means comprises a geared member wherein said geared member is positioned between and engages said first driven means and said second driven means such that linear displacement of the geared member by said first driven means drives said second driven means for rotating said adjustable flap valve and provides position indication of said adjustable flap valve.

Abstract
In a device for controlling a volumetric rate of flow in a guide tube (1), in particular for controlling the volumetric flow of air in a ventilation system or an air-conditioning plant, an adjusting flap (5) is to be arranged variably, in particular rotatably about an axis of rotation (6), in the guide tube (1). In this case, the guide tube (1) is assigned an adjusting device (3) for the adjusting flap (5) and the adjusting device is assigned a controller (4) which can be controlled by a control unit, in particular a room thermostat.
