Abstract
A throttle valve having a housing defining a cavity, with structures providing a flow channel within the cavity, and an inlet and outlet in communication with the flow channel. The throttle valve also includes a valve closure in the form of a plurality of individually-controlled electromagnets disposed in the housing cavity, with each having an armature projectable into the flow channel, so as to influence the cross section of the flow channel and thereby regulate the amount of fluid flow through the flow channel.
