摘要:
An arrangement for the actuation of a gas-exchange disk valve longitudinally guided in the cylinder head of a reciprocating piston which is opened and closed against spring force by two alternately periodically energized electromagnets. An armature coaxial to the disk valve together with an armature disk secured at the same is thereby moved to and fro and stresses a cylindrical torsion rod spring clamped-in at the cylinder head by way of a valve lever pivotally connected at the armature. For compensating manufacturing tolerances and thermal expansion, a magnetizable entrainment disk is arranged in the armature disk with axial play which is threadably connected with the stem end of the disk valve and effects the tight closing thereof.
