摘要

An installation for flushing out a unit (5), such as a gear box, comprises a duct (62), the ends of which are demountabiy engaged with an inlet and outlet of the unit (5) into which oil has been preliminarily introduced, pumping means (63) to cause the oil to circulate around the duct (62) and the unit (5), filtering means (65) to retain the impurities leaving the unit (5) in the oil, and means (6) for causing movement of the rotatable parts of the unit (5) while it is being flushed. The oil is initially fed from and subsequently returned to a closed reservoir (Fig. 1), having attached thereto a closed, constant flow filtering and heating circuit (1) and a second circuit (2) which feeds the oil to unit 5 when required via one of demountable couplings (61). Various valves are controlled by push-buttons via pneumatic actuators. IMAGE
