Valve arrangement

In a valve arrangement for regulating the idling speed of an internal combustion engine by controlling the quantity of air on an intake side of an intake manifold leading to the internal combustion engine, said valve arrangement including a return spring, a movable closure member, and an electromechanical control member having a solenoid arranged for moving said closure member against the force of the return spring via a control element, the improvement comprising:

• a connection of predetermined cross section connecting the intake side of the manifold to an inlet side of the closure member;
• a valve operatively arranged with respect to said connection, said valve being openable in a closed position of said closure member;
• said solenoid includes a movable armature and said control element comprises a push rod connected to said movable structure;
• said push rod is operatively connected so as to open said valve.

• a connection of predetermined cross section connecting the intake side of the manifold to an inlet side of the closure member;
• a valve operatively arranged with respect to said connection, said valve being openable in a closed position of said closure member;
• a throttle valve in said intake manifold dividing said intake side of said intake manifold from an inlet side of said intake manifold;
• a bypass communicating said intake side of said intake manifold with the inlet side of said intake manifold via said connection of said closure member, respectively, the latter being movably mounted in said bypass for opening and closing said bypass via said solenoid and said control element;
• and wherein
• said connection is formed in said closure member communicating said inlet side of the closure member with an outlet side of said closure member;
• said inlet side of the closure member communicates with said inlet side of said intake manifold and said outlet side of said closure member communicates with said intake side of said intake manifold;
• and
• said closed position of said closure member closes said bypass, while said valve opens said connection thereby communicating said intake said of said intake manifold with the inlet side of said intake manifold via said connection and thereby via said bypass.
