    摘要： A choke for use with a carburetor on an internal combustion engine comprises a housing having an air inlet and an air outlet the air outlet being adapted for communication with the air intake of a carburetor. A valve means within the housing includes a valve member and means biassing the valve member in a direction to block the passage of air between the air inlet and the air outlet of the housing. The valve means is responsive to engine vacuum during starting of the engine to move the valve member in a direction against the biassing means to permit air to enter the carburetor from outside the housing via the air inlet and air outlet thereof.

    摘要： A carburetor 9 for feeding separate lean and rich channels 12, 13 of an engine intake duct 14 comprises a body 20 having a mixing passage 22 with an air intake side 24 and an engine outlet side 26. A throttle shutter 16 is rotatable about an axis transverse the mixing passage, and a partition 10 is located within the mixing passage upstream of the throttle shutter. The downstream edge of the partition 10 is adjacent the throttle shutter axis 16A whereby in use of the carburetor the partition defines an extension of the lean and rich channels upstream of the throttle shutter, the partition thus providing substantial isolation between the lean and rich channels for all rotational positions of the throttle shutter. In a preferred embodiment a choke shutter 17 is located upstream of the throttle shutter and is rotatable about a further axis 17 A transverse the mixing passage, the upstream edge of the partition being adjacent to the axis of the choke shutter.
