Title:
HYDRAULIC SOLENOID VALVE FOR AN AUTOMATIC TRANSMISSION OF A VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/149273
Kind Code:
A2
Abstract:
The present invention relates to a hydraulic solenoid valve for an automatic transmission of a vehicle, which moves an armature member and a spool member in the upward and downward directions by means of magnetic force so as to open/shut an inlet port and an outlet port. A first bushing member and a second bushing member installed in a hollow portion of a movement guide member, which guides the movement of the armature member, are coaxially arranged. An air gap is formed between an outer surface of the armature member and an inner surface of the movement guide member, to thereby reduce mechanical processing errors or assembly errors during manufacture or assembly, and improve hydraulic performance and transmission performance.
