Publication number: 20230415171Abstract: A centrifugal separator for cleaning gas containing contaminants includes a stationary casing, a gas inlet, a rotating member, a gas outlet including an outlet opening through a wall of the stationary casing, a drainage outlet arranged in the lower portion of the stationary casing, a drive member for rotating the rotating member, and a stationary axial surface extending into the separation space. The rotating member includes a rotatable axial surface arranged radially outside the stationary axial surface. The rotatable axial surface is arranged at the gas inlet such that liquid contaminants present in the gas to be cleaned is pressed against the rotatable axial surface during operation. The rotating member includes a brim portion extending radially inwards from the rotatable axial surface and forms a ring-shaped sealing gap between the rotating member and the stationary axial surface.Type: ApplicationFiled: November 2, 2021Publication date: December 28, 2023Applicant: Alfdex ABInventor: Mats-Örjan POGÉN

Patent number: 10888879Abstract: An arrangement for cleaning gas includes a centrifugal separator and pre-separation unit. The centrifugal separator includes a stationary casing, enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas from the pre-separation unit, a rotating stack of separation disks, a gas outlet and a drainage outlet for discharging separated liquid impurities. The pre-separation unit is arranged upstream of said inlet of said centrifugal separator, and it comprises a pre-separation inlet having a cross-sectional area A2 and permitting supply of the gas to be cleaned. A2 is larger than the cross-sectional area A1 of the inlet to the separation space of the centrifugal separator. A pre-separation outlet permits supply of gas from the pre-separation unit to the gas inlet of the centrifugal separator.Type: GrantFiled: October 4, 2016Date of Patent: January 12, 2021Assignee: ALFDEX ABInventors: Ronny Jannerstad, Mats-Örjan Pogén, Pedro Hernandez Fraczek

Patent number: 9863296Abstract: A centrifugal separator for cleaning crankcase gas, containing oil, from an internal combustion engine, includes a stationary casing defining a separation space and including a first end portion, an opposite second end portion and an inner wall surface facing the separation space. The separator also includes an inlet channel for the gas to be cleaned, a gas outlet channel for the cleaned gas and an oil outlet for the separated the oil. A centrifuge rotor is provided in the separation space and includes a spindle and a plurality of separation discs carried by the spindle. The centrifuge rotor is rotated to create a rotating gas volume. An oil supply device supplies such a quantity of oil to the separation space that a flowing oil film is created on the inner wall surface during operation of the centrifugal separator.Type: GrantFiled: May 7, 2013Date of Patent: January 9, 2018Assignee: ALFA LAVAL CORPORATE ABInventor: Mats-Örjan Pogén

Patent number: 7022163Abstract: In a vehicle air is compressed for being used in the brake system of the vehicle, for instance. In the compressor, used for the compression, the air is contaminated with oil and solid particles. In order to be relieved from these particles, before the air is conveyed through a drying filter, the compressed is brought to rotation by means of a rotating member in a centrifugal separator. The rotating member may advantageously include a pile of conical separation discs forming flow passages between each other for the compressed air to be cleaned. By means of an efficient cleaning of the compressed air from particles the life time of the drying filter may be increased.Type: GrantFiled: February 13, 2004Date of Patent: April 4, 2006Assignee: Alfa Laval Corporate ABInventors: Mats Olsson, Mats-Örjan Pogén, Ingvar Hällgren, Roland Isaksson, Stefan Szepessy

Patent number: 6571489Abstract: For a single chamber air drier in a compressed air system on a vehicle the volume of dry regeneration air required to regenerate a desiccant in the air drier has to be determined. This can be accomplished in that data regarding system pressure, outdoor temperature and supplied air volume are continuously provided to a compute, which in relation to these parameters controls the supply of regeneration air to the air drier.Type: GrantFiled: September 24, 2001Date of Patent: June 3, 2003Assignee: Haldex Brake Products ABInventors: Sven-Olof Larsson, Mats-Örjan Pogen
