| 摘要 | The present invention connects a return line (44) of the system in which the pump (10) is used to a lubrication chamber (18) at one end of a journal (30) supporting one of the pumping gears (20) in order to pump high temperature hydraulic fluid. The hydraulic fluid which has been cooled by a heat exchanger (50) is then drawn by low pressure in a low pressure region (65) of a pump inlet opening (16), through an interface (60) between bearings (34) supporting the gear journals (30) and the gear journals themselves. In this way, bearings (34) and gear journals (30) are lubricated with hydraulic fluid having a temperature substantially lower than hydraulic fluid in a return line or tank. | ||||||
