Abstract:
1. A valve module for influencing a fluid supply of a fluid-operated load, comprising a valve housing which defines a valve chamber with a fluidically communicating connection to an inlet port and an outlet port and a pilot chamber with a fluidically communicating connection to an operating port, and further comprising a valve member which is movably accommodated in the valve chamber and which is adjustable between a blocking position and a release position in order to influence a free flow cross-section between the inlet port and the outlet port, and further comprising an actuator which is movably accommodated in the pilot chamber and motion-coupled to the valve member, so that a position of the actuator and the valve member coupled thereto can be set as a function of a pressure applied to the pilot chamber, and further comprising a sensor device for detecting a position of the valve member and/or the actuator along a movement axis, wherein the sensor device comprises an electric coil arrangement which forms a ring around at least one fluid port from the group comprising the operating port, the inlet port and the outlet port.
