Description

technical field

[0001] The present invention relates to a valve timing regulation device for controlling the opening and closing timing of an intake valve or an exhaust valve of an internal combustion engine (hereinafter referred to as an engine) such as an engine. Background technique

[0002] A conventional valve timing adjustment device includes: a first rotating body that has a housing that has a plurality of protrusion-shaped shoes (shoes) inside and that forms a hydraulic chamber between the shoes; The front cover and the rear cover of the oil pressure chamber are fixed integrally and rotate integrally with the crankshaft; The multiple blades of the chamber can rotate relatively at a predetermined angle in the first rotating body, and are integrally fixed with the intake or exhaust camshaft, and supply and discharge oil pressure to the oil pump for supplying oil to the sliding part of the engine, and use this Oil pressure is used to control the relative position of th...
