Abstract: The present invention relates to an oil filtration unit (1) for removal of solid contaminants from contaminated oil, the oil filtration unit (1) comprising a housing (2) which comprises a housing inlet (3) adapted to receive contaminated oil from the surroundings and to release the contaminated oil to an inner opening (4) of the housing (2) at a first pressure (p1) and a housing outlet (12) adapted to release filtered oil to the surroundings, and an oil filter (6) for filtering the contaminated oil, the oil filter (6) being arranged in the inner opening (4) of the housing (2) and comprising a filter inlet defined by an outer surface (7) of the oil filter (6), an inner filter volume (8) adapted to receive filtered oil at a second pressure (p2), where the second pressure (p2) is lower than the first pressure (p1), and a filter outlet inside the housing (2) providing fluid/liquid communication between the inner filter volume (8) and the housing outlet (12) in order to release the filtered oil from the inner filt

Abstract: Oil filtration unit for removal of contaminants from oil including a housing with an inlet to receive contaminated oil from surroundings and release oil to an inner opening at a first pressure, an outlet adapted to release filtered oil to surroundings, and an oil filter for filtering oil in the inner opening of the housing. The oil filter includes an inlet with an outer surface, an inner volume to receive filtered oil at a second pressure lower than the first pressure, and an outlet inside the housing providing fluid/liquid communication between the inner volume and the housing outlet. The filter outlet includes a hydraulic resistance providing a fluid/liquid flow restriction between the inner volume and the housing outlet to increase the second pressure inside the inner filter volume and release the oil from the inner filter volume to the housing outlet at a third pressure lower than the second pressure.

Abstract: A device for processing of a liquid that includes a device-input for receiving the liquid to be processed at an input-pressure, a device-output for returning the processed liquid at an output-pressure, and a process chamber having a chamber-inlet and a chamber-outlet, and a feed-line for connecting the chamber-inlet to the device-input. The feed-line includes a multi-stage pump for increasing the pressure of the liquid from the input-pressure to a feed-pressure at the chamber-inlet, a discharge-line for connecting the chamber-outlet to the device-output which discharge-line includes back-pressure means adapted to maintain a discharge-pressure at the chamber-outlet upstream of the back-pressure means at an excess-pressure above the output-pressure, and to reduce the pressure of the liquid from the discharge-pressure to the output-pressure downstream of the back-pressure means. The pump in the feed-line is a first stage of a multiple-stage gear pump.
