摘要： A volumetric-flow controller for adjusting a control flap is movably mounted within a flow channel. A measurement channel has a channel inlet and outlet for connection to the flow channel forming a separate bypass channel branched from the flow channel. A differential pressure sensor arranged in the measurement channel measures a differential pressure prevailing in the flow channel and outputs a corresponding electrical measurement signal. A control unit for electrically activating a flap drive in dependence on the electrical measurement signal outputted by the differential pressure sensor sets a desired volumetric flow rate in the flow channel. At least one air quality sensor arranged in the measurement channel measures an air quality prevailing in the flow channel and outputs a corresponding electrical measurement signal. The control unit electrically activates the flap drive in dependence on the electrical measurement signal outputted by the at least one air quality sensor.

摘要： A relay for closing or interrupting the electric circuit between two relay connection contacts includes two contact springs which are each fixed in an electrically conductive manner to the relay connection contacts with the spring ends thereof facing away from each other and which face each other with the other free, deflectable spring ends thereof. A stationary, electrically conductive contact bridge, against which the free spring ends abut in the closed relay position and from which the free spring ends are lifted in the open relay position, is included. A single solenoid-operated mechanism is for the synchronous, parallel deflection of the two contact springs into the closed or open relay position.

摘要： A regulating flap reduction gear for an electrically driven regulating flap for regulating a gas or liquid volume flow includes two parallel bearing plates between which gear parts are rotatably arranged. A plurality of spacers keep the two bearing plates at a distance from one another. The plurality of spacers are designed as tabs of one, first bearing plate, which are bent by 90° from the plane of the first bearing plate and have at least one lateral projection. The tabs are inserted with their free tab ends into plug-in openings of the other second bearing plate until their at least one lateral projection rests against the second bearing plate.

摘要： A volumetric flow controller for air conditioning and ventilation systems for displacing a control flap that is adjustably supported in the interior of a flow channel includes a differential pressure sensor for measuring a pressure difference prevailing in the flow channel. A control unit displaces the control flap depending on the pressure measured by the pressure sensor for adjusting a target volumetric flow in the flow channel. A first operating element is for selecting one of a plurality of parameters, in particular of control and/or configuration parameters. A second operating element is for adjusting the value of the respective selected parameter. A display is for displaying the currently set value of the respective selected parameter. The first operating element is a push button, a touch-sensitive switch, a touch-sensitive control panel or a contactless operating element for advancing the respective parameter displayed in the display.
