An accelerator (28) having a main body defining a main chamber, a movable member (e.g., a diaphragm (34)) positioned within and dividing the main chamber into a pneumatic chamber (36) and a fuel chamber (38), and a damping orifice (62) (e.g., in the main body) interconnecting the pneumatic chamber (36) with a gas source (e.g., ambient air). The damping orifice (62) has a cross-sectional area less than about 0.002 square inches. To inhibit contamination of the accelerator, a filter (64) can be operatively positioned between the pneumatic chamber (36) and the ambient air.
L'invention porte sur un gicleur de reprise (28) comportant un corps principal contenant une chambre principale, un élément mobile (par exemple une membrane (34)) monté dans la chambre et la divisant en une chambre pneumatique (36) et une chambre à carburant (38), ainsi qu'un orifice d'amortissement (62) (percé par exemple dans le corps principal) reliant la chambre pneumatique (36) à une source de gaz (par exemple l'air ambiant). Ledit orifice (62) présente une section transversale de moins de 0,002 pouce carré. Pour empêcher l'encrassement du gicleur, on peut placer un filtre entre la chambre pneumatique (36) et l'air ambiant.
