Pressure feed to a shaft

A hydraulic fluid feed mechanism that feeds into a shaft of a transmission having a hydraulic control device, by which the hydraulic feed mechanism can be supplied with hydraulic fluid, comprising a transmission housing in which the shaft is held, and a housing cover that is equipped with feed bores, by which the hydraulic fluid is fed from the hydraulic control device into the shaft. A hydraulic fluid line is positioned between the hydraulic or pneumatic control device and a feed bore in the housing cover that extends parallel to the shaft, with this hydraulic fluid line being comprised of a fitting and a tube which is permanently inserted into the fitting at nearly right angles, forming a pressure-tight seal. The fitting is pushed through a transmission housing bore that extends parallel to the shaft, is separably inserted into the feed bore forming a pressure-tight seal, and is axially mounted to the transmission housing by a sealing ring.
