摘要： A full close position limiting member is adapted to be engaged with a valve gear when a valve is driven in a valve closing direction and reaches a full close position of the valve. An intermediate position limiting member is adapted to be engaged with a return spring when the valve is placed on a side of a predetermined intermediate position where a full close position of the valve is located. The intermediate position limiting member receives an intermediate reaction force from the return spring through engagement with the return spring, and the full close position limiting member receives a full close side engaging force from the valve gear. The full close side engaging force and the intermediate reaction force are generally directed in a predetermined direction.

摘要： A carburetor has a throttle element rotatably supported on a throttle shaft and a choke element rotatably supported on a choke shaft. A first coupling element is fixedly connected to the throttle shaft. A second coupling element is connected to the choke shaft. The first and second coupling elements define in a locked position a start position of throttle element and choke element. The locked position is released by rotation of the throttle shaft in opening direction of the throttle element. The locked position is released by rotation of the choke shaft in opening direction of the choke element. One of the first and second coupling elements is an at least partially elastic coupling element. Upon rotation of the choke shaft from the locked position into an open position, the elastic coupling element is elastically deformed and releases the locked position between the first and second coupling elements.

摘要： An intake manifold assembly includes an intake manifold having an inlet configured to receive an air/fuel mixture from a carburetor, an outlet configured to discharge the air/fuel mixture into a combustion chamber, an interior wall at least partially defining an intake passageway fluidly communicating the inlet and the outlet, and an aperture in the interior wall. The aperture is positioned between the inlet and the outlet. The intake manifold assembly also includes a first regulator received in the aperture and at least partially positioned in the intake passageway to effectively decrease the cross-sectional open area of the intake passageway. The first regulator is selectable from a plurality of regulators configured to each be at least partially positionable in the intake passageway. The first regulator is configured to be removed and replaced by a second regulator from the plurality of regulators without disassembly of the intake manifold from the carburetor.

摘要： Disclosed is a throttle device for an internal-combustion engine, in which, on one side of the side wall of a throttle body, there are formed a space for mounting a reduction gear mechanism which transmits the power from a motor to a throttle valve shaft and a default opening setting mechanism for holding a throttle valve opening at a specific opening (default opening) when the ignition switch is in off position, and a gear cover mounting frame which edges the mounting space. The frame is formed lower than the mounting level of the reduction gear mechanism. A gear cover for covering the gear mounting space is attached on the frame. A stopper for defining the default opening and a stopper for defining the full-closed position of the throttle valve are juxtaposed so as to enable position adjustments in the same direction. These stoppers serve to stop a default lever and a throttle gear, thereby enabling downsizing, weight reduction, and rationalization of fabrication and adjustments of an electronically controlled throttle device.
