Title:
ELECTRONIC CONTROL THROTTLE BODY
Document Type and Number:
WIPO Patent Application WO/2002/038929
Kind Code:
A1
Abstract:
An electronic control throttle body comprises a torque motor (20) having a stator and a mover (slider) (25) and a throttle shaft (4) rotated by the torque motor. A rack (25b) serving as teeth is provided to the mover. A gear (30) in engagement with the rack is provided to the throttle shaft (4). The radius of the gear (30) is determined appropriately with respect to the range where the slider (25) moves, and therefore the movement of the slider (25) can be transmitted to the throttle shaft (4) effectively. As a result, a simply-structured electronic control throttle body for efficiently transmitting the drive of a torque motor such as a linear motor to the throttle shaft is provided.
