A pressurised oil reservoir device

Номер: GB0002572188A

A method and apparatus that includes use of a pressurised oil reservoir 16 to provide an oil supply to an internal combustion engine component when the engine is off. The arrangement includes the oil reservoir, a flow restrictor 18, and a one-way valve 14. The oil reservoir is in liquid connection with a main oil gallery 10 via the flow restrictor and the one-way valve, and fills with oil when the engine is on, and releases the oil to a rotating component, such as a turbocharger 12, when the engine is off. The oil reservoir functions as a liquid accumulator, and the reservoir may include a spring actuated piston to pump fluid from the reservoir. The one-way valve prevents oil from the oil reservoir from filling the main oil gallery when the gallery oil pressure falls as the engine is switched-off and permits all the oil from the reservoir to flow to the rotating component. The flow restrictor meters the rate of flow of the oil from the reservoir to allow pressurised lubrication to the component ...

A method for heating a lubricating system. At low temperatures, lubricating oil has a high viscosity which requires more energy to be overcome than at higher temperatures. The novel method speeds up the heating behavior and thereby reduces the energy requirement of lubricating systems.
