VALVE FOR CONTROLLING VOLUME FLOWS

摘要

The invention proposes a valve (1) for controlling volume flows, in particular in a heating and/or cooling system of a motor vehicle, having a disk-shaped valve body (2) with at least one control opening (3) which, to control the volume flow, interacts with a disk-shaped sealing body (10) having at least one passage opening (11), wherein the disk-shaped valve body (2) has an external toothing (49) into which a pinion (42) engages in order to rotate the valve body (2). According to the invention, the pinion (42) and the external toothing (49) of the disk-shaped valve body (2) interact with one another by means of an evoloid toothing (43; 44). The valve according to the invention is provided for controlling volume flows, in particular in a heating and/or cooling system of a motor vehicle.
