Title:
FLUID CONTROL VALVE AND EVAPORATED FUEL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/235284
Kind Code:
A1
Abstract:
A fluid control valve (38) is made compact by changing the shape of a communication passage (84) formed inside the fluid control valve. The fluid control valve (38) includes a valve casing (56), an electric valve (52), and a relief valve (54). The valve casing (56) includes: a main passage (74) that has a first valve port (71) sealed by the electric valve (52); a bypass passage (90) for bypassing the first valve port (71); a first valve chamber (65) communicating with the downstream side of the first valve port (71) and housing the electric valve (52); and a second valve chamber (67) communicating with the upstream side of the first valve port (71) and housing the relief valve (54). The bypass passage (90) includes the communication passage (84), which allows the first valve chamber (65) and the second valve chamber (67) to communicate. The communication passage (84) opens to a side surface (65A) of the first valve chamber (65) and/or a side surface of the second valve chamber (67).
