Abstract
A carburetor with a throttle valve is provided in which a linkage member is in communication with the throttle valve. An idle down handle can be moved from an unactuated position to an actuated position and is in communication with the throttle valve. Movement of the idle down handle to the actuated position causes the throttle valve to be placed into the closed position. When the idle down handle is in the unactuated position the throttle linkage member can cause the throttle valve to be moved back and forth between the open and closed positions.
Claims5
A carburetor, comprising:
- a housing;
- a throttle valve that can be moved between an open position and a closed position, wherein a throttle linkage member is in communication with the throttle valve and the throttle valve shaft is rigidly attached to the housing, wherein the throttle valve shaft rotates relative to the housing;
- a revolve bracket rigidly attached to the throttle valve shaft, wherein the revolve bracket rotates relative to the housing;
- a throttle linkage member clip that is rotationally mounted to the revolve bracket, wherein the throttle linkage member is attached to the throttle linkage member clip and can apply force thereto that is communicated to the throttle valve through the revolve bracket and the throttle valve shaft to move the throttle valve from the open position to the closed position,
- an idle down handle that can be moved from an unactuated position to an actuated position, wherein the idle down handle is in communication with the throttle valve, wherein movement of the idle down handle from the unactuated position to the actuated position causes the throttle valve to be placed into the closed position, wherein when the idle down handle is in the unactuated position the throttle linkage member can cause the throttle valve to be moved from the open position to the closed position and can cause the throttle valve to be moved from the closed position to the open position;
- a shore that is rigidly attached to the housing;
- a transmission bracket that is rotationally mounted to the shore, wherein the transmission bracket defines an idle down transmission pin slot and a linkage member slot;
- a linkage member clip that is rotationally mounted to the revolve bracket;
- a linkage member that is attached to the linkage member clip, wherein an end of the linkage member is disposed through the linkage member slot;
- an idle down transmission shaft attached to the handle;
- an arm that extends from the idle down transmission shaft and that is rigidly attached to the idle down transmission shaft;
- and
- an idle down transmission pin that is rigidly attached to the arm and that is disposed in the idle down transmission pin slot;
- wherein the idle down handle is capable of being rotated, and wherein rotation of the idle down handle from, the unactuated position to the actuated position causes the idle down transmission shaft to rotate that causes the arm and the idle down transmission pin to rotate to cause the idle down transmission pin to ride within the idle down transmission pin slot to cause the transmission bracket to rotate relative to the shore to cause the linkage member to move to cause the linkage member clip to move to cause the revolve bracket to rotate to cause the throttle valve shaft to rotate to cause the throttle valve to rotate from the open position to the closed position.
