Abstract:
1. A regulating valve to regulate a flow rate of gaseous or liquid fluid comprising: a magnetic drive having a proportional behavior; a core arranged in the magnetic drive to be movable in an axial direction and to serve for opening and closing a valve seat; and at least two flat springs being arranged on an axial end of the core, the at least two flat springs being stacked upon each other, wherein the at least two flat springs are all disc-shaped and all include two concentric rings which are connected to each other by arms, wherein the at least two fiat springs are positioned relative to each other such that one flat spring is rotated relative to the other flat spring about a common central axis of the at least two flat springs and which is parallel to the axial direction such that one flat spring is rotationally offset relative to the other flat spring, and wherein the at least two flat springs guide the core and provide a friction-free movement of the core.
