Abstract

Vergaser an Motorwerkzeugen weisen häufig Gemischanreicherungssysteme auf, die durch eine Bedienungsperson zum Anlassen des Motorwerkzeugs betätigt werden. Bei bekannten Vergasern, Anreicherungseinrichtungen und Motorwerkzeugen besteht die Gefahr einer unsachgemäßen Handhabung, die dazu führen kann, daß ein Anlassen erschwert bzw. ein Betrieb unterbunden wird.
Es wird ein Vergaser (26, 100) vorgeschlagen, der mit einer Anreicherungseinrichtung (30, 30', 102) und einer Drosseleinrichtung (32, 32') wirksam verbundene Steuerelemente (56, 68) aufweist, die derart zusammenwirken können, daß die Handhabung vereinfacht und die Funktion des Vergasers (26, 100) verbessert wird. Darüber hinaus wird ein Motorwerkzeug (10) mit einem solchen Vergaser (26, 100) vorgeschlagen.
Vergaser und Motorwerkzeuge werden beispielsweise in der Garten-, Rasen- bzw. Grundstückspflege eingesetzt.
