Abstract (en)
[origin: JPH06159164A] PURPOSE: To obtain excellent service performances and achieve most suitable harmonization between and favorable effects on components by rendering the ratio of the resultant force of a main closing element to a movable mass to be smaller than the ratio of the resultant force of an auxiliary closing element to the movable mass. CONSTITUTION: A valve 1 for the clocked feeding of volatile fuel constituents out of a free space 3 of a fuel tank 4 into an intake manifold 5 of an internal combustion engine 6 is provided. Particularly, a main closing element 11 has a movable mass mI and an auxiliary closing element 12 has a movable mass mII. The main closing element 11 and the auxiliary closing element 12 sealingly contact corresponding valve seats through the force of a valve spring under no voltage condition. The main closing element 11, when actuated, is shiftable to an open position by a resultant force Fres I and the auxiliary closing element 12 is shiftable to an open position by a resultant force Fres II. The ratio Fres I/mI is smaller than the ratio Fres II/mII. This condition is most suitable for the valve 1.
