Claim:
A variator for an infinitely variable toroidal drive, comprising: a support trunnion ( 30 ), including journals ( 37 , 38 ) for supporting the support trunnion ( 30 ) so as to be pivotable about an axis (Y-Y), a roller ( 21 ), rotatable supported on the support trunnion ( 30 ) so as to be rotatable about an axis (X-X), with at least two bearings ( 24 , 28 , 32 , 33 ) being disposed between the roller ( 21 ) and the support trunnion ( 30 ), and a lubricant supply arrangement including at least one lubricant line ( 48 , 49 , 50 ) for supplying lubricant to a lubrication point ( 53 , 54 ) in the region of the bearings ( 24 , 28 , 32 , 33 ), said at least one lubricant line ( 48 , 49 , 50 ) being connected to a main lubricant line ( 41 , 42 , 43 , 47 ) formed by a bore oriented approximately in the longitudinal direction of, and extending through, one of the journals ( 26 ) of an eccentric shaft ( 22 ) on which the roller ( 21 ) is rotationally supported and which faces the support trunnion ( 30 ), there being a continuous connection between parts of the main lubricant line ( 41 , 42 , 43 ) arranged in the support trunnion ( 30 ) and the main lubricant line ( 41 , 42 , 43 , 47 ), and the at least one lubricant line ( 48 , 49 , 50 ) having a throttle ( 51 , 52 ) in the region adjacent the lubrication point ( 53 , 54 ).
