Document Type and Number:

WIPO Patent Application WO/2016/208359

Kind Code:

A1

Abstract:

The objective of the present invention is to improve the responsiveness of an electromagnetic flow rate control valve provided for the purpose of causing a suction valve to close, and to perform control so as to achieve a desired discharge flow rate. A flow rate control valve is equipped with a fixed core arranged on the inner circumferential side of a coil, a yoke arranged on the outer circumferential side of the coil, and a cover part opposing the coil in the axial direction. The fixed core has an enlarged part that makes contact with the cover part in the axial direction and the size of which increases toward the coil. The cover part is restricted in the axial direction only at the area of contact with the fixed core.
