Abstract
An oil separator includes a heating device that heats liquid stored in a liquid storage portion, a connecting pipe that connects the liquid storage portion to an external device that utilizes oil, an opening/closing device that selectively opens and closes the flow path of the connecting pipe, and a determination device that determines whether the liquid stored in the liquid storage portion should be delivered to the external device. The opening/closing device is configured to open the flow path of the connecting pipe when the determination device determines that the liquid accumulated in the liquid storage portion should be delivered to the external device.
Claims14
An oil separator comprising:
- a housing;
- and
- an impingement member arranged in the housing, wherein
- the oil separator is configured to introduce air containing oil into the housing, to cause the air to strike the impingement member to separate liquid containing the oil from the introduced air, and to store the liquid in a liquid storage portion,
- the oil separator further comprises:
- a connecting pipe that connects the liquid storage portion to an external device that utilizes the oil;
- an opening/closing device that selectively opens and closes a flow path of the connecting pipe;
- and
- a determination device that determines whether the liquid stored in the liquid storage portion should be delivered to the external device, and
- the opening/closing device is configured such that, when the determination device determines that the liquid stored in the liquid storage portion should be delivered to the external device, the opening/closing device opens the flow path of the connecting pipe.
An oil separator comprising:
- a housing;
- and
- an impingement member arranged in the housing, wherein
- the oil separator introduces air containing oil into the housing and causes the air to strike the impingement member to separate liquid containing the oil from the introduced air and stores the liquid in a liquid storage portion,
- the oil separate is installed in a vehicle in which a diesel engine is mounted,
- the liquid storage portion includes an ejection port that is connected to a combustion unit provided in an exhaust purification device that traps particles contained in exhaust gas of the diesel engine, and
- the liquid stored in the liquid storage portion is supplied to the combustion unit of the exhaust purification device.
A compressed-air drying system that traps water and oil contained in compressed air, the system comprising:
- at least one of an air dryer and an oil mist separator, wherein
- the air dryer is configured to trap water and oil contained in compressed air during a loading mode operation and to eject the trapped water and oil during an unloading mode operation, and
- the oil mist separator is configured to trap oil contained in compressed air during a loading mode operation and to eject the trapped oil during an unloading mode operation;
- and
- an oil separator that is configured to store the ejected water and oil in a liquid storage portion,
- wherein the oil separator is arranged above the at least one of the air dryer and the oil mist separator in a vertical direction.
