スロットル装置
Document Type and Number:
Japanese Patent JP7458499
Kind Code:
B2
Abstract:
A throttle device according to the present invention includes: a throttle valve (30) which opens and closes a main passage; a body (10) which includes the main passage, a secondary passage that detours around the throttle valve, and a gas passage that introduces fuel vapor gas into the main passage; a first valve body (40) which opens and closes the secondary passage; a second valve body (60) which opens and closes the gas passage; and a solenoid actuator (90) which has a plunger (91) that applies drive force to the first valve body and the second valve body so as to close the first valve body and the second valve body in a resting position, open only the first valve body at a maximum stroke position, and open only the second valve body in a stroke region between the resting position and a middle stroke position that has less stroke volume than the maximum stroke position. Thus, it is possible to limit increases in dedicated components, the structure can be simplified and made low-cost and compact, and the fuel vapor gas can reliably be collected without emission to the outside.
