Abstract
In order to provide a carburettor unit for motorized equipment, in particular hand-operated motorized equipment such as a chain saw, a trimmer, a lawn-cutting appliance, a foliage clearing appliance or suchlike, having a housing , in which a throttle valve and a choke valve are held so as to be movable respectively between a closed position and an open position, which overcomes the disadvantages of the prior art and in which an incorrect position between the throttle valve and the choke valve is avoided, it is proposed that a locking element is provided, which is adjustable through the movement of the throttle valve and cooperates with the choke valve such that a movement of the choke valve into the closed position is locked when the motorized equipment is set in operation.
