Document Type and Number:
Japanese Patent JP4149763
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and device for detecting and controlling a position of a valve element 54 of an injection valve. SOLUTION: The valve element 54 can move between each of stoppers 41, 42 in the valve element 53, and a movement setting of a valve member 54 is obtained from a present position of the valve member 54. The present position and sucking and separating movement of the valve member 54 are picked up by a sensor element 59 and are transmitted to a control device 57. Actuator members 2, 55 for operating the valve member 54 are controlled by the control device 57, and the valve member 54 is optimized in terms of a speed and abrasion, and is moved. Input/cutoff phases 47, 48 are included in a course of an attraction current 46 of the actuator members 2, 55, and periods and time points of them are dependent on a signal of the sensor element 59 in the valve element 53.
