Responsiveness of an electromagnetic flow-rate control valve provided for closing a suction valve is improved and a discharge flow rate is controlled to a desired value. A flow-rate control valve includes a fixed core arranged on an inner circumferential side of a coil, a yoke arranged on an outer circumferential side of the coil, and a cover portion opposed to the coil in an axial direction, in which the fixed core has an enlarged portion in contact with the cover portion in the axial direction and enlarging toward the coil, and the cover portion is regulated in the axial direction only by a contact portion with the fixed core.
