Title:
VALVE DEVICE AND FUEL EVAPORATED GAS PURGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/225540
Kind Code:
A1
Abstract:
In a valve device, an outflow port (155) is inserted into an engine-side port formed in an intake tube (22) so as to lead into an intake passage. A leaking port (4) has a leak passage (41) into which evaporated fuel from an inflow port (154) can flow regardless of an allowing state or an inhibiting state. The leaking port (4) is inserted into the engine-side port. A seal member (1550) provides a sealed state between the outflow port and the engine-side port. A seal member (40) provides a sealed state between the leaking port and the engine-side port. When the outflow port and the leaking port have moved in the direction away from the engine-side port, the sealed state of one seal member is undone before that of the other seal member. It is thereby possible to minimize external leaking of gas when a proper mounted state is undone.
