Abstract: To effectively prevent uneven wear of a moving mover 70 and to stabilize the control characteristics by a valve. Rotation force is exerted to the mover 70 by the fluid flowing from the first chamber to the second chamber, or vice versa, which are formed at the opposite ends of the mover 70. With respect to a flow passageway 110 formed within an anchor 72 and for allowing passage of the fluid therethrough, there are provided a passageway portion 111 which is disposed along the axial direction and another passageway portion 112 which crosses the axial direction. By this, rotation force is generated at the time the fluid passes from the former passageway portion 111 to the latter passageway portion 112 (or vice versa) which crosses the axial direction.

The fuel metering unit is disposed in the high-pressure pump, and the outlet of the regulating valve discharges into the low-pressure region of the high-pressure pump. The above design features make a fuel metering unit possible that is capable of metering the exact quantity of fuel desired in the applicable engine operating state to the high-pressure pump of the CR system.
