HYDRAULIC CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To enhance the working responsiveness of a valve stopping mechanism 14 using a working oil discharged from a phase changing mechanism 12. SOLUTION: The phase changing mechanism 12 and valve stopping mechanism 14 are hydraulically controlled independently of each other while they use one oil pump 10 in common. The working oil discharged from the phase changing mechanism 12 when it advances the working angle phase of an intake valve, is supplied to the valve stopping mechanism 14 via a circulating oil passage 48.
