22...Roller, 24...Rotating shaft of the throttle valve 18 on the second stage side, 26...Arm member, 28...Semi-cylindrical pin, 30...Flat surface of the pin 28.

Claims

[Claims for Utility Model Registration] In a carburetor having a first-stage side and a second-stage side, a return member is fixed to one end of a drive shaft of the throttle valve on the first-stage side so as to be rotatable together with the drive shaft. an arm member fixed to one end of a rotating shaft of the throttle valve on the second stage side so as to be rotatable together with the rotating shaft; and an arm member on a side of the return member that is close to the throttle valve on the second stage side. a roller rotatably pivotally connected to an end thereof; a semi-cylindrical pin having a flat surface fixed to an end of the arm member on the side adjacent to the throttle valve on the first stage side; and the throttle valve on the first stage side. When the first stage throttle valve rotates in the closing direction, the rotatable roller contacts the flat surface of the semi-cylindrical pin and prevents the first stage throttle valve from rotating in the second stage.
An interlocking mechanism for a throttle valve of a carburetor that transmits information to a throttle valve on the stage side.
