| 摘要 |
A pressure regulating valve having a compression spring fixed in a valve housing for positioning a valve plunger connected to a magnetic armature in the position above a valve seat and not electromagnetically excited, in order to create a connection between at least two pressure medium channels opening into the valve housing, and having a further compression spring disposed coaxially to the first compression spring in the valve housing, having the characteristic that the first compression spring is designed as a control spring forming a stroke and force-specific spring drive by adjusting the spring rates of both compression springs to the force/distance curve of an electromagnet by varying the current in an exciter coil, wherein the further compression spring is designed as a variably adjustable spring acting opposite to the control spring.
