A rotating passage feed system for admitting pressure means into two machine parts (hub part ( 2 ), shaft ( 3 )) which rotate relative to one another about a common axis is provided. Conduits ( 17 ) that convey the pressure means are located in the shaft ( 3 ) and are joined to pressure means connections ( 6 ) via tapped holes while a connecting part ( 5 ) in which ring channels ( 8 ) are provided is also joined thereto. A central sleeve ( 9 ) is joined to the connecting part ( 5 ) in a non-rotatable manner. The connecting part ( 5 ) and the central sleeve ( 9 ) are produced in an inexpensive manner as lightweight structure formed from sheet metal through a shaping process.
