Automatic gearbox lubricating system - has chamber of larger cross=section for connecting two oil drillings

摘要

The lubricating system is for part of an automatic gearbox, having a pressure source (10) to whose outlet port (44) a first oil drilling is connected at one end. A second oil drilling (46) is connected at one end to the part (32) to be lubricated, while a chamber (40) connects the other ends of the two drillings together, and is of larger free cross-section than either. The three can be connected together in series. ADVANTAGE - Gives ideal flow rate without risk of choking by dirt.
