Abstract:
1. An internal combustion engine valve drive arrangement having three axially displaceable cam elements ( 10 , 11 , 12 ) with a switch gate ( 13 ), coupled to the cam elements ( 10 , 11 , 12 ), the switch gate ( 13 ) including gate tracks ( 14 , 15 ) with track segments ( 16 , 17 , 18 , 19 ) and switching segments ( 20 , 21 , 22 , 23 , 24 , 25 ), formed in three different gate elements ( 26 , 27 , 28 ) and being disposed between two cam elements ( 10 , 11 ) for displacing the cam elements ( 10 , 11 , 12 ) with the two gate elements ( 26 , 27 ) disposed adjacent the cam elements ( 10 , 11 ) being formed integrally with the respective adjacent elements ( 10 , 11 ), the track segments ( 16 , 17 , 18 , 19 ) and the switching segments ( 20 , 22 , 23 , 25 ) being formed to extend continuously over the gate elements ( 26 , 27 , 28 ) so that, in a partial area, the guide tracks ( 14 , 15 ) have a double function providing for an insertion or a removal of a switch pin ( 31 , 32 ) and for a switching of the displaceable cam elements ( 10 , 11 , 12 ).
