Abstract: A method and device are provided which allow easy and reliable prediction of abnormality of a solenoid valve 1 before failure by detecting operating times of the solenoid valve 1 and discriminating, from the operating times, whether the changeover operation thereof is normal or abnormal. To achieve this, the position of a spool 6 at a stroke end is detected by position detecting means 11 connected to the solenoid valve 1. The movement starting time from the time point when the driving signal for the solenoid valve 1 is turned on or turned off to the time point when the valve member begins to move from the stroke end, and the movement completion time therefrom to the time point when the spool 6 arrives at the stroke end, are measured in a signal processing circuit 12 from the detected position signal and a clock signal. The signal processing circuit 12 discriminates whether the changeover operation of the valve member is normal or abnormal by comparing these operating times with a plurality of standard values previously inputted in the signal processing circuit 12. A display signal is output in response to the discrimination result.

Abstract: A control valve couple to a steering shaft of the steering wheel controls a flow power fluid supplied to a power cylinder for steering. A rotor magnet is secured on an input shaft of the control value. A concentric-circle shaped stator coil faces the rotor magnet means. A casing functioning also as an iron core yoke is mounted on a housing of the control valve for receiving the rotor magnet and the stator coil. When the input shaft is rotated in response to the operation of the steering wheel, an electromotive force is produced to detect a displacement in rotation of the input shaft.
