MULTI-SLOPE CANISTER PURGE SOLENOID VALVE

摘要

A multi-slope canister purge solenoid (CPS) valve has a diaphragm-controlled valve downstream of the solenoid-actuated valve. The diaphragm-controlled valve has two diaphragms that between themselves define a chamber space that is communicated to intake manifold vacuum. One of the two diaphragms is exposed to atmospheric pressure while the other is exposed to the interior of the CPS valve.
