摘要:
A disclosed lubrication system for a turbofan engine includes a pump for driving lubricant through a lubrication circuit, at least one sensor generating a signal indicative of an engine operating condition and at least one valve for controlling a flow of lubricant through the lubrication circuit. A controller controls operation of the valve to vary the flow of lubricant based on the engine operating condition to maintain lubricant flow within predefined operating limits.

An oil supply system for an internal combustion engine includes an oil pump, a heat exchanger, an oil feed line and two oil outlet lines, for conveying the oil from the oil pump through the oil feed line to the heat exchanger and from the latter through the two oil outlet lines. In a system of this type, there is provision for the internal combustion engine to be configured as a piston engine and for the heat exchanger to be configured as a water/oil heat exchanger, and for one oil outlet line to be connected to oil spray nozzles of the piston engine and for the other oil outlet line to be connected to a main oil line of the piston engine. An oil supply system of this type is distinguished by its simple design and functionality, and permits optimum cooling and lubrication of the relevant components of the engine.

An internal combustion engine that includes a crankcase having a crankcase pressure defined within the crankcase relative to an ambient pressure. The crankcase pressure varies in response to operation of the internal combustion engine. A crankcase pressure regulator is in fluid communication with the crankcase, and the crankcase pressure regulator includes a first passageway defining a first flow path, a second passageway defining a second flow path in a parallel arrangement to the first passageway. When the crankcase pressure is less than a first predetermined pressure, the first valve moves to the open position to allow a fluid flow into the crankcase through the first passageway. When the crankcase pressure is greater than a second predetermined pressure, the second valve moves from the closed position to the open position to allow a fluid flow from the crankcase through the second passageway.

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.
