Claims

[Claims for Utility Model Registration] (1) A valve seat, a housing formed with a fluid passage opening to the valve seat, a valve body facing the valve seat, and a housing fixed to a continuous portion of the valve body. a valve body drive mechanism comprising a coil wound around an armature and a permanent magnet provided on a fixed body near the outer periphery of the armature; and a fail that urges the valve body toward a predetermined small opening position. In the idle speed control valve for an internal combustion engine, the idle speed control valve is equipped with a safe mechanism and controls an intake flow rate that bypasses an intake throttle valve by changing an opening area of a fluid passage that opens to the valve seat as the valve body rotates. Permanent magnets each having a magnetic flux density having a predetermined temperature characteristic are arranged in a continuous part of the body and a fixed body in the vicinity of the continuous part, and the valve body is moved to a predetermined small opening position by the magnetic force acting on the permanent magnets. An idle speed control valve for an internal combustion engine, characterized in that it is provided with a failsafe mechanism that biases the valve towards the target. (2) The permanent magnet in the fail-safe mechanism is arranged so that the relative positional relationship between the magnetic poles is stabilized at a predetermined small opening of the valve body and at a changed position.Claim 1 of the Utility Model Registration Claim. Idle speed control valve for the internal combustion engine described. (3) The permanent magnet in the fail-safe mechanism is such that the relative positional relationship of its magnetic poles is such that the valve body contacts the stopper with an urging force at a predetermined small opening position. An idle speed control valve for an internal combustion engine according to scope 1.
