摘要： An internal combustion engine for a motor vehicle includes a crankcase. The crankcase has having at least two oil separation devices and having a return device. The return device has at least one first return channel that is flowable through by a first portion of the oil separated from the blow-by gas with a first of the oil separation devices, through which the first portion of the separated oil is guided from the first oil separation device into the reservoir. The return device also has at least one second return channel that is at least partially spaced apart from the first return channel and is flowable through by a second portion of the oil separated from the blow-by gas via the second oil separation device, through which second return channel the second portion of the separated oil is guided from the second oil separation device into the reservoir.

摘要： A fluid pump system for an aircraft has a rotatable component having first and second fluid ports, each port in fluid communication with a selected interior portion of the component, the portions being spaced from each other. A valve controls allows a first flow rate through the first fluid port and allows a second flow rate through the second fluid port when the component is in a first angular orientation. The valve allows a third flow rate through the first fluid port and allows a fourth flow rate through the second fluid port when the component is in a second angular orientation.

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.

摘要： A quantitative one-way oil gas lubricant system and a method for a 4-stroke engine, including a preceding stage quantitative oil intake orifice that is connected to a lubricant case on a wall of a crankcase of the 4-stroke engine, and a final stage quantitative airflow orifice disposed at a cylinder cover of the 4-stroke engine, are provided. A diameter of the preceding stage quantitative oil intake orifice D1 and a diameter of the final stage quantitative airflow orifice satisfy an equation: D1/D3=0.8-1.5, wherein a one-way connected oil gas lubricant channel is disposed between the preceding stage quantitative oil intake orifice and the final stage quantitative airflow orifice. A lubricant oil sucked from the preceding quantitative oil intake orifice by the crankcase flows along the oil gas lubricant channel and lubricates the engine parts that the channel passes through in turns. Finally, a minute quantity of waste oil gas that flows out from the final stage quantitative airflow orifice is introduced into a cylinder of the 4-stroke engine and is to be burned completely. The supply quantity of the lubricant oil may be controlled, and no extra lubricant oil gas may flow out from the final stage quantitative airflow orifice, therefore, the quantitative and one-way lubricating is realized.

摘要： A method of supplying a bearing compartment with fluid includes the steps of pumping a fluid from a main reservoir to a bearing compartment through a main supply passage which includes one or more passage segments. During a positive gravity condition, the pumping step is performed using a main pump arranged in the main supply passage. The main reservoir includes upper and lower portions. The main supply passage is in fluid communication with the lower portion. Fluid is provided from the main reservoir to the bearing compartment through a secondary supply passage that is fluidly connected to at least one segment of the main supply passage in response to a negative gravity condition. The secondary supply passage is in fluid communication with the upper portion.

摘要： An auxiliary oil circuit for a heat-generating assembly having a main oil sump and a fluid pump for controlling oil flow from the sump includes a first fluid passage in communication with the pump. The circuit additionally includes a remote reservoir for receiving sump oil via the first passage and an orifice in the first passage for controlling an amount of sump oil transferred to the reservoir. The circuit additionally includes an active first valve in the first fluid passage for selectively opening and closing communication between the sump and the reservoir. The circuit also includes a second fluid passage in communication with the auxiliary reservoir for returning the oil from the reservoir to the sump. Furthermore, the circuit includes an active second valve arranged in the second passage for selectively opening and closing communication between the reservoir and the sump.
