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.
Claims18
A carburetor, comprising:
- a throttle valve that is movable between an open position and a closed position;
- a choke valve that is movable between an open position and a closed position;
- and
- an idle down handle that is movable between an unactuated position and an actuated position, the idle down handle being in communication with the throttle valve;
- when the idle down handle is in the unactuated position, the throttle valve is moveable between the open position and the closed position of the throttle valve independent of the idle down handle;
- when the idle down handle is in the actuated position, the throttle valve is placed into the closed position so that the throttle valve is not movable to the open position;
- and
- the movement of the idle down handle between an unactuated position and an actuated position not affecting movement of the choke valve between the open position of the choke valve and the closed position of the choke valve.
5 more elements
A carburetor, comprising:
- a housing;
- a throttle valve that is movable between an open position and a closed position within the housing;
- a revolve bracket configured to rotate the throttle valve with the revolve bracket being rotatable relative to the housing;
- and
- a transmission bracket that is rotationally mounted to the housing;
- a bracket linkage member in rotatable communication with the revolve bracket, the bracket linkage member being in movable communication with the transmission bracket such that the bracket linkage member is movable upon movement of the transmission bracket;
- an idle down transmission shaft in movable communication with the transmission bracket;
- the idle down transmission shaft being rotatable between an actuated position and an unactuated position, such that rotation of the idle down transmission shaft to the actuated position causes the transmission bracket to rotate relative to the housing to move the bracket linkage member to cause the revolve bracket to rotate to cause the throttle valve to rotate from the open position to the closed position and prevents the throttle valve from being moved from the closed position to the open position until rotation of the idle down transmission shaft to the unactuated position.
