<p>An evaporative emissions purge system utilizes a proportional solenoid valve (20,220) to control the purge or flow of vapors from the canister (14,114) to the engine manifold (24). The proportional solenoid valve provides a precise fluid flow control and simplifies the overall system. The proportionaly solenoid valve may also be combined with the canister flow control diaphragm (21) assembly and the vacuum regulation assembly (106) to obtain a single, multifunctional unit for enhanced performance and cost savings. <IMAGE></p> |
