Abstract

Improvements in electromagnetic valves for hydraulic governments and similar, especially for use in mining operations, which present in the valve housing an electromagnetic drive device and a valve device operated by it, characterized in that a valve is provided in the valve device servo valve actuated by the electromagnetic actuator and a main valve governed by this, and because the electromagnetic actuator, the servo valve and the main valve are arranged in a row axially within an elongated, approximately bar-shaped housing, whose connections are they have on the front face of the housing.
