Patent ID: 8322317

Claim:
A valve timing control apparatus comprising: a driving side rotational member rotating synchronously with a crankshaft of an internal combustion engine; a driven side rotational member arranged coaxially with the driving side rotational member and rotating synchronously with a camshaft for opening and closing a valve of the internal combustion engine; a fluid pressure chamber formed at one of the driving side rotational member and the driven side rotational member; a dividing portion formed at the other one of the driving side rotational member and the driven side rotational member so as to divide the fluid pressure chamber into an advanced angle chamber and a retarded angle chamber; and a fluid control valve portion arranged orthogonally relative to the camshaft at an opposite side of the camshaft so as to dispose the driving side rotational member and the driven side rotational member between the fluid control valve portion and the camshaft, the fluid control valve portion including a first linearly moving member linearly moving in an orthogonal direction relative to the camshaft, thereby controlling supplying and discharging of a fluid relative to the advanced angle chamber and the retarded angle chamber, wherein the fluid control valve portion is positioned orthogonally to an axis of the camshaft.
