Abstract
A dynamic engine oil pickup system is disclosed. The dynamic engine oil pickup system includes a scavenge pump and a pickup tube assembly in fluid communication with the scavenge pump. The pickup tube assembly includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations and a flow control operable to control a flow of engine oil between the at least two different oil pickup locations and the scavenge pump. The flow control includes a suction valve, and movement of the suction valve is controlled by selectively applying a high pressure oil to a head of the suction valve.

A dynamic engine oil pickup system comprising:
- a scavenge pump;
- a pickup tube assembly in fluid communication with the scavenge pump, wherein the pickup tube assembly includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations;
- and
- a flow control in fluid communication with the scavenge pump and the pickup tube assembly, wherein the flow control is operable to control a flow of engine oil between the at least two different oil pickup locations and the scavenge pump.
A dynamic engine oil pickup tube assembly comprising:
- at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations;
- and
- a flow control in fluid communication with the at least two pickup tube portions, wherein the flow control is operable to control a flow of engine oil between the at least two different oil pickup locations and a scavenge pump.
An internal combustion engine including a dynamic engine oil pickup system, the dynamic engine oil pickup system comprising:
- a scavenge pump;
- a pickup tube in fluid communication with the scavenge pump, wherein the pickup tube includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations;
- and
- a flow control in fluid communication with the scavenge pump and the pickup tube, wherein the flow control is operable to control a flow of engine oil between the at least two different oil pickup locations and the scavenge pump.
An internal combustion engine including a dynamic engine oil pickup system, the dynamic engine oil pickup system comprising:
- a first scavenge pump;
- a first pickup tube assembly in fluid communication with the first scavenge pump, wherein the first pickup tube assembly includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations;
- a first flow control in fluid communication with the first scavenge pump and the pickup tube assembly, wherein the first flow control is operable to control a flow of engine oil between the at least two different oil pickup locations and the first scavenge pump;
- at least one other scavenge pump;
- at least one other pickup tube assembly in fluid communication with the at least one other scavenge pump, wherein the at least one other pickup tube assembly includes at least two oil pickup portions operable to pickup engine oil from at least two different oil pickup locations;
- and
- at least one other flow control in fluid communication with the at least one other scavenge pump and the at least one other pickup tube assembly, wherein the at least one other flow control is operable to control a flow of engine oil between the at least two different oil pickup locations and the at least one other scavenge pump.
