Patent ID: 8127644

Claim:
Rotary transmission leadthrough with: a shaft ( 3 ) able to turn about a longitudinal axis running in the longitudinal direction (L) with at least one longitudinal borehole ( 26 , 27 , 28 ) running in the longitudinal direction (L); in which a push rod ( 43 , 44 , 45 ) is arranged and can move back and forth relative to the shaft ( 3 ) in the longitudinal direction (L); and with at least one opening ( 22 , 23 ) in a lateral wall of the shaft which extends to a coordinated longitudinal borehole ( 26 , 27 , 28 ); and at least one push fork ( 12 , 13 , 14 ) which can travel in the longitudinal direction (L) outside the shaft ( 3 ) and is coordinated with one of the push rods ( 43 , 44 , 45 ); and an active connection running through the coordinated opening ( 22 , 23 ) to the coordinated longitudinal borehole ( 26 , 27 , 28 ) between the coordinated push fork ( 12 , 13 , 14 ) and the coordinated push rod ( 43 , 44 , 45 ), which transmits a back and forth motion of the coordinated push fork ( 12 , 13 , 14 ) relative to the shaft ( 3 ) onto the coordinated push rod ( 43 , 44 , 45 ), and enables a rotary motion of the shaft ( 3 ) relative to the coordinated push fork ( 12 , 13 , 14 ).
