摘要： A fuel vapor storage canister (10) having a screen module (52) between carbon granules (94) in the canister and a purge port (50) of the canister. The screen module (52) includes a module body (54) defining a plenum (62), a flat plastic foam screen (72) seated on an uninterrupted edge of a raised boss (60) on the module body around the plenum, and a retainer (74) clamped to the module body over the flat foam screen. A tubular stem (68) on the module body (54) plugs into a socket (36A) in the storage canister (10). An interference fit between the tubular stem (68) and the socket (36A) prevents migration of carbon granules between the socket and the tubular stem. The foam screen (72) is exposed to the carbon granules through a window in a planar side (76) of the retainer (74) which planar side, in a seated position of the retainer on the module body, cooperates with the uninterrupted edge of the raised boss (60) in compressing a segment (84) of the foam screen to define a seal around the window. Hooks (90) on the module body (54) cooperate with resilient loops (82) on the retainer (74) in maintaining the integrity of the seal around the foam screen (72) by preventing release of the retainer from its seated position on the module body.

摘要： A purge control device for an evaporative control system comprises a single housing (20) having two solenoid actuated valves (32,34) controlling parallel orifices (40,70) leading from an inlet chamber (36) to an exit flow path (38). The two solenoid valves (32,34) have different sized orifices (40,70) to provide different flow capacities. Purge flow is controlled by an electronic control module (48) which regulates the duty cycle of the solenoids (32,34). Each valve (32,34) receives its own signal so that the flow through the orifices (40,70) is individually controlled.

摘要： A canister (l0), adapted to store fuel vapour discharged from a fuel tank by adsorption on a bed (l2) of material such as activated carbon, has an inlet chamber (28) that forms a trap for liquid fuel. Liquid fuel is purged from the canister (l0) through a purge tube (26) that has a small liquid-purge hole (32) at the bottom of the chamber (28) and a large vapour-purge hole (34) spaced above the bottom of the chamber (28).
