Document Type and Number:
Japanese Patent JPH0476019
Kind Code:
B2
Abstract:
A lubrication scavenge system for an engine bearing compartment or the like utilizing a gear pump with two or more independent inlets with separate flow paths through the pump. The inlets and flow paths are maintained separate from each other by the use of inlet and discharge seal arcs to avoid any fluid communication therebetween. The pump can operate to pump different fluids through each inlet with the fluid being either a gas or liquid or a mixture of both and with the pump continuing its pumping action when there is an instantaneous interchange in the fluid being pumped at each inlet as can occur when the engine bearing compartment is subjected to varying positive and negative gravity forces.
