Title:
THROTTLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146248
Kind Code:
A1
Abstract:
A throttle device of the present invention is provided with: a throttle valve (30) which opens and closes a main passageway (12); a body (10) which includes the main passageway (12) and a sub-passageway (14) that bypasses the throttle valve (30); and an adjusting screw (40) which is threaded into the body (10) to adjust the passageway area of the sub-passageway (14). The body (10) includes a collision wall (16) which is formed upstream of the adjusting screw (40) so as to protrude into the sub-passageway (14), and with which a fluid is caused to collide. In this way, it is possible to capture, upstream of the adjusting screw, foreign matter that has entered intake air, and to maintain the initial setting of the adjusting screw for a long period.
