PCT No. PCT/DE94/00124 Sec. 371 Date Oct. 21, 1994 Sec. 102(e) Date Oct. 21, 1994 PCT Filed Feb. 8, 1994 PCT Pub. No. WO94/19810 PCT Pub. Date Sep. 1, 1994A solenoid valve control circuit for controlling an actuation current of a solenoid valve when the valve is to be adjusted from its flow-permitting position into its closed position so that the actuation current is initially adjusted to a value beyond the current value at which the valve begins to drop out. However, the actuation current is subsequently adjusted back to the range which lies between the current value at which the valve goes into the closed position and the current value at which the valve goes into its flow-permitting position.
