Abstract
A control mechanism (20; 70) and a method for use in an installation for transporting bulk material, granular material or powdery material through a conveyor line (1) with the aid of a pressurized gaseous medium. The control mechanism (20; 70) is arranged for being connected to the conveyor line (1) for the purpose of introducing a pressurized gaseous medium (15) therein and comprises a connecting opening (24) for connecting the control mechanism (20; 70) to an inlet (25) in the conveyor line (1), an intake (26) for gaseous medium (15), which is in communication with the connecting opening (24), valve means (28; 71), which operatively engage the intake (26), and means (31, 32, 35, 50, 51; 32) for controlling the valve means (28; 71) associated with the pressure of the gaseous medium in the conveyor line (1). The control mechanism (20; 70) is arranged for directly controlling the control valve (28; 71) in response to the sensed pressure in the conveyor line (1) for the purpose of metering the pressurized gaseous medium (15) that is being delivered thereto.
