Patent ID: 7125355

Claim:
A regulatable continuously variable transmission for a motor vehicle comprising: an encircling device ( 3 ) which rotates around first and second pairs of cone pulleys ( 1 , 2 ), the first pair of cone pulleys ( 1 ) is disposed on an input shaft and the second pair of cone pulleys ( 2 ) is disposed on an output shaft, and both the first and second pairs of cone pulleys ( 1 , 2 ) each have an axially fixed cone pulley and an axially movable cone pulley, and cabling and lubricating oil being supplied to the encircling device ( 3 ) and the first and second pairs of cone pulleys ( 1 , 2 ) via a nozzle; wherein the nozzle includes a plurality of discharge openings ( 7 , 8 ) spaced along and communicating with a fluid supply passage having a flow diameter ( 9 , 10 ) that diminishes in a flow direction ( 13 ) between discharge openings ( 7 , 8 ) so that at each flow diameter ( 9 , 10 ), a product of a fluid flow rate and a cross section area of the flow diameter ( 9 , 10 ) is a constant.
