A valve timing control apparatus comprises a rotary member drivingly connected to the crankshaft for rotation with rotation of the crankshaft, and a drive mechanism for transmitting rotation of the rotary member to the camshaft. The drive mechanism includes a piston member provided for reciprocation to rotate the camshaft with respect to the rotary member. The piston member has a pressure chamber formed therein. The piston member is urged resiliently in a first direction. The piston member is movable in a second direction opposite to the first direction in response to a pressure introduced into the pressure chamber. The valve timing control apparatus also includes first and second conduit. The first conduit has a first outlet for connection to the pressure chamber. The second conduit has a second outlet for connection to the pressure chamber. The second outlet is spaced away from the first outlet in the first direction of movement of the piston member. First and second command signals are produced according to engine operating conditions. A pressure is introduced through the first conduit in the presence of the first command signal. A pressure is introduced through the second conduit in the presence of the second command signal.
