Document Type and Number:
WIPO Patent Application WO2002061289
Kind Code:
A3
Abstract:
A fluid transfer (100) system includes elongated conduits (113) connected at one end with couplings to a plurality of fluid reservoirs (105, 107, 109) of a machine or engine and at the other end with a control valve (116) for selective quick evacuation. Evacuation is powered by a pump (128) operably connected to the control valve. Another embodiment includes a first pump for the evacuation of an engine oil reservoir and a second pump for the selective evacuation of transmission and hydraulic fluid reservoirs. The control valve and the pumps may be operated remotely through electrical switches on brackets or on a service panel. Associated method of removing fluids and replacing fluids from a plurality of reservoirs includes coupling the fluid transfer system to the reservoirs.
