The invention relates to a camshaft variator device for an internal combustion engine which includes a crankshaft and a camshaft. The invention includes: a first component which is rigidly connected to the camshaft of the engine, such that the rotation of the first component causes the camshaft to rotate; a second component which is rotated by the crankshaft of the engine; a third component which connects the first and second components to one another and which, in turn, rotates the first component in relation to the second component in order to vary the position and partial speed of the camshaft in respect of the crankshaft; and a fourth component which is used to impart a longitudinal and reciprocating longitudinal movement to the third component. The purpose of the device is to enable the opening and closing time and duration of the valves to be varied by varying the position and partial speed of the camshaft in relation to the crankshaft.
