Pressure supply to a continuously adjustable automatic transmission in particular a clasping transmission

A pressure supply between a variator shaft and a pressure chamber ( 6 ) for the axial displacement of the mobile disc of a pair of conic pulleys of a continuously adjustable automatic transmission, which includes a longitudinal borehole ( 7 ) and radial boreholes ( 8, 9 ) in a variator shaft ( 1 ), as well as a radial borehole ( 10 ) in the locating disc. For each pressure chamber ( 6 ) there are at least two piercing radial boreholes made in the variator shaft, which are axially shifted from each other and rotated approximately 90° between themselves. The oil can run over the longitudinal borehole of the variator shaft and over the radial boreholes through the radial borehole in a locating disc of a pressure chamber ( 6 ), in such a way that the oil flow is always ensured regardless of the axial position or of the tangential location of the locating disc regarding the variator shaft.
