Abstract

Ein Vergaser (1) für einen Verbrennungsmotor umfasst in einem Vergasergehäuse (2) einen Gemischaufbereitungskanal (3) mit einer Drosselklappe (4) und einer Chokeklappe (22), die jeweils drehbar angeordnet sind. Eine Hebelanordnung umfasst einen auf einer Drosselklappenwelle (5) befestigten Gasstellhebel (7) und einen auf einer Chokewelle (8) befestigten Chokestellhebel (9). Die Drosselklappe (4) und die Chokeklappe sind in mehreren Betriebsstellungen einstellbar. Es ist eine Vorrichtung zur Entriegelung zwischen dem Gasstellhebel (7) und dem Chokestellhebel (9) bei einer Notaus-Betätigung vorgesehen.
