Claims (12)

1. A roller device for use in a variator with a toroidal raceway, comprising a roller mounted in a ferrule and a pipe for introducing coolant flows to the roller to remove heat from the roller during operation of the roller device, the pipe including at least two mutually opposite outlet openings designed to direct coolant to opposing parts of the roller, characterized in that each outlet includes or more openings and disposed at an angle relative to each other so as to direct the flow of coolant to different parts of the outer contact surface of the roller.
 2. The device according to p. 1, characterized in that the casing contains two oppositely located outlets for directing coolant to the outer contact surface of the roller.
 3. The device according to any one of p. 1 or 2, characterized in that the holes are arranged at an angle relative to each other to direct the coolant up and downstream to the outer contact surface of the roller.
 4. A device according to any preceding claim, characterized in that it comprises at least one spray rod, which is located partially around, but at a radial distance from the outer contact surface of the roller.
 5. The device according to p. 4, characterized in that at least one spray rod includes a plurality of outlet openings.
 6. A device according to any preceding claim, characterized in that the outlet openings comprise nozzles.
 7. The device according to any one of paragraphs. 4-6, characterized in that at least one spray rod is located so as to direct the coolant to or near a point at which the roller forms or loses contact with another part of the variator.
 8. A device according to any preceding claim, characterized in that the coolant comes from a variator lubrication system in which said device is installed.
 9. The device according to claim 1, characterized in that the cage is operatively connected via a rod to the double-acting piston of the roller control cylinder, the rod having a channel passing through it for transporting coolant to the pipeline, the rod having an end surface open for effect creating pressure of the coolant, and the double-acting piston has an opposing surface, also open for supplying coolant under pressure, thus counteracting any axial load on the stem t, at least partly opposite effect on the confronting surface of the double-acting piston.
 10. The device according to p. 9, characterized in that the mutually opposing surfaces act so as to form a cavity into which coolant is supplied, and the device also contains an axially located supply pipe protruding into the cavity to supply coolant to it.
 11. The device according to p. 10, characterized in that it also contains an axially extending channel in the double-acting piston for receiving fluid, and it is made with the possibility of movement relative to the supply pipe to simplify the flow of fluid into the cavity regardless of the axial position of the piston.
 12. A variator with a toroidal raceway containing one or more roller devices according to any preceding claim
