Abstract
Official abstract text for this publication.
A hydraulic pressure control valve is received in a center hole of a vane rotor that is rotatable relative to a housing. A first tubular portion and a second tubular portion are fitted with each other to form an oil accumulation chamber. The oil accumulation chamber accumulates at least one of oil outputted from a gap between the housing and the vane rotor, and oil discharged from an oil passage communicated with the advancing chamber or the retarding chamber.
First claim
Opening claim text (preview).
What is claimed is: 1. A valve timing control apparatus that controls opening timing and closing timing of one of an intake valve and an exhaust valve of an internal combustion engine, which is opened and closed by a driven-side shaft of the internal combustion engine, through changing of a rotational phase between a driving-side shaft of the internal combustion engine and the driven-side shaft, the valve timing control apparatus comprising: a housing that is rotatable integrally…
