Engine idle speed air control

摘要: A control device for bypassing intake air around a closed throttle valve of an operating engine while it is idling. The has main flow controlling bypass in the passageway and movable to open positions by diaphragm actuated vacuum controlled pilot solenoid. valve, plunger solenoid are all movably received on supported stationary slide rod which preferably extends into coil adjacent only one end cantilever fashion. includes body with piston head clearance out passage bore outlet side passageway. An annular seat located at upstream through moves its axial travel between fully valve. also flexible disc engageable close same. controllably peeled off wedge shaped face during initial opening peripherally cooperate controllable vary cross sectional area hence rate as function incremental along rod.
