ABSTRACT:
A hydraulic fluid feed mechanism that feeds into a shaft (1) of a transmission having a hydraulic control device, by which the hydraulic feed mechanism can be supplied with hydraulic fluid, comprising a transmission housing (3) in which the shaft is held, and a housing cover (7) that is equipped with feed bores (8, 9), by which the hydraulic fluid is fed from the hydraulic control device into the shaft (1). A hydraulic fluid line (12) is positioned between the hydraulic or pneumatic control device and a feed bore (9) in the housing cover (7) that extends parallel to the shaft (1), with this hydraulic fluid line being comprised of a fitting (13) and a tube (14) which is permanently inserted into the fitting at nearly right angles, forming a pressure-tight seal. The fitting (13) is pushed through a transmission housing bore (15) that extends parallel to the shaft (1), is separably inserted into the feed bore (9) forming a pressure-tight seal, and is axially mounted to the transmission housing (3) by a sealing ring (20).
