A refiner device for refining of a liquid, wherein the refiner device includes a housing provided with a liquid inlet for unrefined oil or fuel, a liquid outlet for refined oil or fuel, an air inlet for supplying a flow of air into the housing, and an air outlet for discharging air and contaminants removed from the liquid. The refiner device further includes a liquid receiving plate arranged inside the housing, the refiner device arranged such that when liquid has passed through the liquid inlet during operation of the device, the liquid is contacted with an upper surface of the liquid receiving plate before it reaches the liquid outlet, and at least one heating element arranged to directly or indirectly heat the liquid while the liquid is in contact with the liquid receiving plate. The refiner device further includes a hollow air-guiding member arranged at the liquid receiving plate.

An oil conditioner is provided for removing impurities from oil, such as water, fuel and glycol, to increase engine life and efficiency. An evaporator assembly includes an upper plate, a lower plate, with a heater unit sandwiched between the two. To increase the efficiency of the evaporator assembly, materials are selected so that the upper plate thermal conductivity property is greater than the lower plate thermal conductivity property; and, optionally, the lower plate includes a reflective surface to direct thermal radiation toward the upper plate. This unique design enables oil conditioning with reduced power consumption and improved heating compared to existing technology.

A method of deaerating a mixture of fluid and air according to an example of the present disclosure includes the steps of communicating a mixture of a fluid and air into an open area of a reservoir directly against a wall of the reservoir to separate at least some of the fluid from at least some of the air. The reservoir is disposed about an axis of a rotatable shaft, and the reservoir has a curved radially outer wall and a curved radially inner wall joined by curved end walls that face circumferentially relative to the axis. The mixture is communicated against a first one of the curved end walls. The fluid is held within the reservoir after the separating.

A suction oil filter for a transmission or combustion engine including an oil filter housing made of plastic and having at least one suction channel that can be connected to a suction side of a suction pump and at least one return channel feeding into the suction channel for a pressurized oil flow returned by the suction pump. The return channel is provided with at least one nozzle in the region of the opening thereof into the suction channel, as well as at least one pressurized oil supply pipe which is linked to the return channel and can be connected to a pressure side of the suction pump, and which is connected to the oil filter housing via at least one contour connection.

A shaft seal device mounted rotating electrical machine includes; a rotating electrical machine which includes a rotating shaft equipped with a shaft seal device having an inlet portion and an outlet portion of seal oil, a main oil tank in which the seal oil supplied to the shaft seal device is stored, a seal oil cleanup tank which includes an inlet portion connected to an outlet portion of the main oil tank, and has an oil level regulating valve, a degassing pump which includes an inlet portion connected to an outlet portion of the seal oil cleanup tank, a pressure regulating valve which is disposed between the outlet portion of the seal oil cleanup tank and an outlet portion of the degassing pump, a differential pressure control valve which is disposed between the outlet portion of the degassing pump and the inlet portion of the shaft seal device.

A de-aerator for a lubrication system, has: a housing defining an air-oil inlet, an oil outlet, and an air outlet of the de-aerator; a rotor received within the housing and rotatable relative to the housing about a central axis, the rotor having blades distributed about the central axis and extending at least partially radially relative to the central axis, flow passages extending between the blades, the rotor having a hub circumferentially extending around the central axis and around the blades, the hub having a peripheral wall oriented radially inwardly and defining a fore opening leading to the flow passages; and a gap between the housing and the hub of the rotor, a portion of the housing received within the fore opening and axially overlapping the peripheral wall of the hub, the gap having a fore gap inlet between the portion of the housing and the peripheral wall of the hub.

Techniques for managing a lubricant fluid include storing a lubricant fluid that includes liquid water in an interior volume of a reservoir, which includes a vapor space above the lubricant fluid that encloses water vapor; circulating, with a blower, a first airflow from the vapor space to an ambient environment to remove at least a portion of the water vapor to the ambient environment; circulating a second airflow to a heater in fluid communication with the vapor space within the interior volume of the reservoir; heating the second airflow with the heater; circulating the heated airflow into the vapor space to reduce a relative humidity of the vapor space; and releasing at least a portion of the liquid water from the interior volume of the reservoir through a control valve coupled to the reservoir.

A vacuum dehydrator for removing water from lube oil including a vacuum chamber having a contaminated lube oil contact zone, a lube oil inlet for introducing a water contaminated lube oil into the contact zone, a hot air inlet for introducing a heated air stream into the contact zone, a decontaminated oil outlet fluidly connected to the decontaminated oil collection zone, and a wet air outlet fluidly connected to the disengagement zone. The lube oil inlet and the hot air inlet are configured to introduce and contact the water contaminated lube oil and the hot air in the contact zone, producing a dehydrated oil received into the decontaminated oil collection zone and a wet air stream containing entrained oil droplets received into the disengagement zone. The disengagement zone includes a tortuous divergent flow path traversing from a disengagement zone inlet to the wet air outlet.

A de-aerator is provided that includes a body, a cover panel, a fluid inlet, a helical fluid passage, at least one partition, and at least one fluid outlet. The body extends between opposing first and second axial ends. The body has a sidewall, a base panel, and an internal cavity. The fluid inlet is in communication with the body and is configured to direct fluid tangentially into the internal cavity.
