Title:
CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2020/202705
Kind Code:
A1
Abstract:
A control valve (CV) according to the present invention is configured such that when a third opening part (M3), which is an auxiliary opening part, and a third discharge opening (E3), which is an auxiliary connection opening, do not overlap, the third opening part (M3) and a continuous discharge opening (E4) overlap. Thus, for example, when a flow rate of cooling water for continuous circulation is required, such as during a cold start, cooling water guided through an internal passage (118) is discharged via the continuous discharge opening (E4) in addition to cooling water guided from a bypass passage (BL), thereby ensuring a sufficient flow rate of cooling water for continuous circulation.
