VENTILANORDNING FOR REGLERING AV TOMGANGSVARVTALET HOS OTTOMOTORER, I SYNNERHET FORDONSMOTORER

摘要

A valve system for regulating the idling speed of Otto engines, particularly automobile engines, by controlling the amount of air on an outlet side with an electromechanical setting member which comprises a valve element which limits the effective outlet cross section, the valve element being moveable by an electric drive member and being in communication on one side with the outlet side, and having a circuit which controls the setting member as a function of the speed of rotation. The valve element is mounted substantially free of friction and means are provided for exerting on the valve element a compensating force which opposes the force caused by the suction vacuum.
