Title:
HYDRAULIC CONTROL DEVICE OF VALVE MECHANISM
Document Type and Number:
Japanese Patent JP3952119
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic control device of a valve mechanism capable of certainly displaying filtering work by an oil filter by restraining a steep rise of manufacturing cost and preventing passing of foreign matter through clearance between the oil filter and a supply oil passage.
SOLUTION: The oil filter 24 is provided in the supply oil passage 20 in the upstream of a change-over control valve 2, a tapered inclined part 29 to contract diameter toward the downstream is formed on an inner periphery of the supply oil passage 20, an inclined part 30 corresponding to the inclined part 29 is formed on an outer periphery of the oil filter 24, force to the downstream is made to act on the oil filter 24 by a flow of working oil, the inclined part 30 of the oil filter 24 is made to constantly make pressure contact with the inclined part 29 of the supply oil passage 20, and passing of the foreign matter through between the both inclined parts 29, 30 is prevented.
