Abstract
An air control valve for a fuel cell vehicle includes: a valve housing formed with air flow paths; valve members configured to selectively open or close the air flow paths; and a drive unit configured to rectilinearly operate the valve members so that the valve members rectilinearly move from a first position at which the air flow paths are closed to a second position at which the air flow paths are opened, such that it is possible to obtain an advantageous effect of improving sealing performance and improving stability and reliability.
Claims17
An air control valve for a fuel cell vehicle, the air control valve comprising:
- a valve housing formed with air flow paths wherein the air flow paths comprise:
- a first flow path and a second flow path separated from the first flow path;
- valve members configured to selectively open or close the air flow paths;
- a drive unit configured to rectilinearly operate the valve members so that the valve members rectilinearly move from a first position at which the air flow paths are closed to a second position at which the air flow paths are opened, wherein the drive unit comprises:
- a driving source configured to provide driving power, and a power converting part connected to the valve members and configured to convert the driving power of the driving source into a rectilinear motion of the valve members;
- and
- a bypass flow path configured to connect the first flow path and the second flow path and allow air introduced into the first flow path to selectively flow to the second flow path,
- wherein the valve members comprise:
- a first valve disc configured to selectively open or close the first flow path by being rectilinearly moved by the drive unit;
- and
- a second valve disc configured to selectively open or close the second flow path by being rectilinearly moved by the drive unit, and
- wherein the power converting part comprises:
- a first gear configured to be rotated by the driving source;
- and
- a second gear connected to the valve members and configured to engage with the first gear and move the valve members by being rectilinearly moved by the rotation of the first gear.
