Abstract
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 ().
