摘要： An electromagnetic valve assembly comprises a movable valve member, a valve seat, an electromagnet for attracting the movable valve member toward the valve seat, and a non-magnetic intermediate member interposed between the movable valve member and the valve seat. The non-magnetic intermediate member magnetically isolates the movable valve member from the valve seat so that the movable valve member is free from the residual magnetism of the valve seat to prevetn valve sticking.
