throttle return spring 节气门回位弹簧
throttle return damper 油门回位缓冲器
throttle return damoper 节气门回位缓冲器
return spring of throttle 节气门回位弹簧
A return switch (RS) is responsive to the motor throttle body, and a pressure sensitive switch (PSS) is responsive to the accelerator pedal position.
返回开关(RS)是顺应电机油门身体，压力感应开关(PSS)的回应是由于油门踏板的位置。
Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed.
常开：当线圈通电时，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
When the coil power, the pilot valve by the spring return, pilot hole closed throttle valve chamber pressurized by the piston return spring and thrust, the electromagnetic valve is closed.
当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
