Abstract: A second rotor and a third rotor are accommodated in a first rotor. A fitting portion of the third rotor is located in an engagement hole of the second rotor to engage the third rotor with the second rotor. The third rotor is rotational about an axis, which is eccentric to an axis of the first rotor, to vary a relative rotational phase of the first rotor to the second rotor and to accelerate and decelerate rotation of the second rotor. When friction arises between the second rotor and the fitting portion, a frictional force acts in a direction to reduce a rotational moment acting on the third rotor. A friction coefficient between the second rotor and the fitting portion is greater than a friction coefficient between ferrous objects.

The communication pipe makes a second passage of the second injection valve and a back pressure chamber of the first injection valve communicate with each other. The ECU controls an electric actuator of the second injection valve so as to switch first injection control and second injection control according to the required injection amount. In the first injection control, a second valve body is opened for a predetermined time or more so that back pressure lowers to the pressure of opening a first valve body. In the second injection control, the second valve body is opened for less than the predetermined time so that the back pressure does not lower to the pressure of opening the first valve body.
