Abstract
This invention relates to an oil reservoir system for an engine comprising: an oil container which includes an oil reservoir, which is in fluidic communication with an oil circulation system of an engine, a ventilated headspace and an oil filter located at the interior of said oil container. The invention also relates to a method for deaeration of an oil of an oil reservoir which is in fluidic communication with an oil circulation system of an engine. Furthermore, the invention relates to a vehicle comprising the oil reservoir system.
Claims17
An oil reservoir system comprising:
- an oil container comprising an oil reservoir which is in fluidic communication with an oil circulation system of an engine, a vent port, a headspace which is in fluidic communication with the vent port, and an inlet and an outlet which each independently comprise a port comprising a self-sealing valve or a non-return valve;
- and
- an oil filter located in an interior of the oil container and in fluidic communication with the oil reservoir,
- wherein the oil filter is constrained such that when oil is circulated by the oil circulation system of the engine, oil is forced through the oil filter and out into a body of oil in the oil reservoir, such that when oil having entrained gas flows through the oil filter, the entrained gas is separated from suspension in the oil.
An oil reservoir system comprising:
- an oil pan located within a sump of an engine, wherein the oil pan comprises an oil reservoir which is in fluidic communication with an oil circulation system of the engine, wherein the oil circulation system comprises a pump in the oil reservoir, and wherein the pump is arranged to pump oil from the oil reservoir to the engine via a first outlet of the pump;
- a headspace which is in fluidic communication with a ventilation system of the engine;
- and
- an oil filter located in the oil pan and in fluidic communication with the oil reservoir, wherein the oil filter is in fluid communication with a second outlet of the pump which supplies oil which has been pressurized by the pump, and wherein the oil filter is constrained such that when oil is circulated by the oil circulation system of the engine, oil is forced through the oil filter and out into a body of oil in the oil reservoir, such that when oil having entrained gas flows through the oil filter, the entrained gas is separated from suspension in the oil.
A method of reducing the amount of entrained gas in an oil of an oil reservoir system for an engine, which engine comprises an oil circulation system, said method comprising the steps of i) locating an oil filter in an oil reservoir within an oil container of the oil reservoir system, wherein the oil container comprises an inlet and an outlet which each independently comprise a port comprising a self-sealing valve or a non-return valve;
- and ii) constraining the oil filter such that, when oil is circulated by the oil circulation system of the engine, oil is forced through the oil filter and out into a body of oil in the oil reservoir, such that when oil having entrained gas flows through the oil filter, the entrained gas is separated from suspension in the oil.
A method of reducing the amount of entrained gas in an oil of an oil reservoir system for an engine, which engine comprises an oil circulation system, said method comprising the steps of i) locating an oil filter in an oil reservoir within an oil pan located within a sump of the engine, wherein the oil circulation system comprises a pump in the oil reservoir, wherein the pump is arranged to pump oil from the oil reservoir to the engine via a first outlet of the pump, and wherein the oil filter is in fluid communication with a second outlet of the pump which supplies oil which has been pressurized by the pump;
- and ii) constraining the oil filter such that, when oil is circulated by the oil circulation system of the engine, oil is forced through the oil filter and out into a body of oil in the reservoir, such that when oil having entrained gas flows through the oil filter, the entrained gas is separated from suspension in the oil.
An oil reservoir system comprising:
- an oil container comprising an oil reservoir which is in fluidic communication with an oil circulation system of an engine, a vent port, a headspace which is in fluidic communication with the vent port, and an inlet and an outlet which each independently comprise a port comprising a self-sealing valve or a non-return valve;
- and
- an oil filter located in an interior of the oil container and in fluidic communication with the oil reservoir,
- wherein the oil filter is constrained such that when oil is circulated by the oil circulation system of the engine, oil is forced through the oil filter and out into a body of oil in the oil reservoir, such that when oil having entrained gas flows through the oil filter, the entrained gas is separated from suspension in the oil and gas exiting the oil filter passes through the body of oil in the oil reservoir to the headspace.
