Variable valve drive of a combustion piston engine

A variable valve train of a reciprocating internal combustion engine, the variable valve train comprising:

• a switchable cam follower including:
• a primary lever configured to be supported by a supporting element at a first end of the primary lever and by a valve stem of a gas exchange valve at a second end of the primary lever, the primary lever configured to be in following contact with at least one primary cam between the first end and the second end, and
• a secondary lever configured to be in following contact with at least one secondary cam, the second lever pivotally coupled to the primary lever via a coupling pin,
• wherein the coupling pin is axially movably guided in a transverse bore of the primary lever via a switching pin, the switching pin is axially movably mounted in a transverse bore of the secondary lever, the coupling pin configured to be displaced into an opposing coupling bore of the secondary lever in opposition to a restoring force of a first spring element, and
• wherein an outer axial end of the switching pin projects out of the secondary lever so as to connect to a leaf spring coupled to a switching rod, the switching rod arranged above the switchable cam follower and configured to extend parallel to a camshaft, the switching rod configured to be longitudinally displaced in opposition to a restoring force of a second spring element from a rest position to a switching position via an actuator.
