Abstract

In a variator for an infinitely variable toroidal drive including a support trunnion rotatably supporting motion transmitting traction rollers and means for the lubrication and cooling of the components of the variator, in particular of the bearings, throttles are provided in the lubricant lines directly adjacent to the bearings whereby the pressure level for lubricant is raised for an improved control of the flow of the lubricant to the different lubricating points.
