Abstract
In an oil supply device for a machine having different categories of oil consumers, to which respectively one supply loop provided with at least one pump is provided, it is possible to achieve a simple structure and advantageous operating costs in that all supply loops can be provided with oil from a common oil tank, that at least one supply loop having a self-cleaning filter provided with an outlet for oil sludge, and that a separating device is provided, which can be charged at least with the oil sludge from each self-cleaning filter and which has a clean oil outlet terminating in the oil tank.
Claims27
An oil supply device for a machine having lubricating oil consumers and hydraulic oil consumers, comprising:
- a common oil supply for supplying oil to all consumers;
- at least one oil supply loop including a self-cleaning filter connected to said common oil supply and to one of the consumers, said self-cleaning filter having an outlet for oil sludge;
- and
- a separating device connected to said oil sludge outlet of said self-cleaning filter, said separating device having a clean oil outlet connected to said common oil supply.
An oil supply device for a reciprocating engine, such as a Diesel engine, having lubricating oil consumers and hydraulic oil consumers, comprising:
- a common oil supply for supplying oil to all consumers;
- an oil supply loop for each oil consumer, each said oil supply loop having at least one pump, at least one filter and a return line, each said oil supply loop and its return line being connected to said common oil supply;
- and
- a separating device having a sediment outlet and a clean oil outlet terminating in said common oil supply, wherein at least the oil supply loop connected to the hydraulic oil consumers includes at least one self-cleaning filter and a further filter located upstream therefore, wherein the mesh size of said further filter is larger than that of said self-cleaning filter, and wherein each self-cleaning filter has an oil sludge outlet connected to said separating device.
An oil supply device for a reciprocating engine, such as a Diesel engine, having lubricating oil consumers and hydraulic oil consumers, comprising:
- a common oil supply for supplying oil to all consumers;
- an oil sump;
- an oil supply loop for each consumer, each said oil supply loop having at least one pump and at least one filter;
- and
- a return flow line for connecting said oil sump with said common oil supply, wherein the leak and return oil accumulating in the area of the hydraulic oil consumers as well as the leak oil running off the lubricating oil consumers is supplied to said oil sump, wherein at least said oil supply loop leading to the hydraulic oil consumers is provided with a self-cleaning filter, and wherein said oil supply loop leading to the hydraulic oil consumers branches off upstream of said oil supply loop leading to the lubricating oil consumers.
An oil supply device for a reciprocating engine, such as a Diesel engine, having lubricating oil consumers and hydraulic oil consumers, comprising:
- a common oil supply for supplying oil to all consumers;
- an oil sump;
- an oil supply loop for each consumer, each said oil supply loop having at least one pump and at least one filter;
- and
- a return flow line for connecting said oil sump with said common oil supply, wherein the leak accumulating in the area of the hydraulic oil consumers as well as the leak oil running off the lubricating oil consumers is supplied to said oil sump, wherein at least said oil supply loop leading to the hydraulic oil consumers is provided with a self-cleaning filter, and wherein said oil supply loop leading to the hydraulic oil consumers branches off upstream of said oil supply loop leading to the lubricating oil consumers.
