Title:
VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/181863
Kind Code:
A1
Abstract:
A check valve (71) can regulate an operating fluid flowing through inflow holes (ORs), and has a valve body (700), which is formed in a cylindrical shape by rolling up a single plate. The check valve (71) has a narrow-width section (710) that is formed in a portion of the valve body (700) in the circumferential direction thereof, and a wide-width section (721) and a wide-width section (722) that are formed in locations in the circumferential direction of the valve body (700) other than that of the narrow-width section (710), and have widths that are greater than the width of the narrow-width section (710), said widths being the lengths in the axial direction of the valve body (700). A rotation regulation section (90) regulates the rotational location of the valve body (700) such that at least a portion of the wide-width section (721) and the wide-width section (722) is located within a maximum distance interval (Sbd), which is the interval with the greatest distance among the distances between inflow holes (ORs) that are neighboring in the circumferential direction of an annular groove section (511).
