Abstract
Abstract Comprising a throttle member, in an induction passage of a carburetor body, a control element actuated by the user and connecting means operatively interconnecting the throttle member and the control element. The connecting means comprise a spindle carrying the throttle member and a sleeve coaxial with the spindle and integral with the control element. The spindle and sleeve are relatively rotatable and the sleeve is rotatable in the carburetor body. An electromagnetic coupling normally interconnects the spindle and sleeve but is capable of disconnecting the spindle and sleeve in the event of malfunctioning of the device. Separate springs bias the spindle and the sleeve toward positions normally corresponding to a position of the throttle member substantially closing the induction passage.
