Title:
THROTTLE DEVICE AND FUEL EVAPORATIVE GAS RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/163238
Kind Code:
A1
Abstract:
This throttle device comprises: a throttle valve (30) for opening and closing a main passage (12); a body (10) having the main passage (12), a secondary passage (14) bypassing the throttle valve (30), and gas passages (15, 14b) for introducing fuel evaporative gas into the main passage (12); a first adjustment valve (41) for adjusting the passage area of the secondary passage (14); a drive source (50) for driving the first adjustment valve (41); and a second adjustment valve (61) for adjusting the passage area of the gas passage (15). The second adjustment valve (61) is driven by the driving force from the drive source (50). Thus, a lower cost and a reduction in size can be achieved while suppressing an increase in specialized components, and fuel evaporative gas can be recovered reliably without being discharged to the outside.
