<p>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.</p> |
