Abstract
An accelerator having a main body defining a main chamber, a movable member (e.g., a diaphragm) positioned within and dividing the main chamber into a pneumatic chamber and a fuel chamber, and a damping orifice (e.g., in the main body) interconnecting the pneumatic chamber with a gas source (e.g., ambient air). The damping orifice has a cross sectional area less than about 0.002 square inches. To inhibit contamination of the accelerator, a filter can be operatively positioned between the pneumatic chamber and the ambient air.
