ROTOR ATTACHMENT STRUCTURE AND CENTRIFUGE
An attachment fitting is attached inside a rotor hole. The attachment fitting is made up of a main body, first and second pieces disposed in a piece placement hole formed in the main body so as to pass therethrough in a direction orthogonal to a rotation central axis of a rotor, a leaf spring including two arm portions, and a retainer that is mounted on the main body and puts a base of the leaf spring between the retainer and the main body. The first and second pieces have grooves into which the arm portions of the leaf spring are inserted. When the rotor rotates, the first and second pieces protrude from the piece placement hole by the centrifugal force against the spring force of the leaf spring and make contact with a rotor coupling portion of a shaft. In a structure that allows the rotor to be attached to the shaft by simply being put onto the shaft, assembly on the rotor's side can be easily performed.
HOUSING FOR A CENTRIFUGAL SEPARATOR
A housing for a centrifugal separator is disclosed, wherein the centrifugal separator is configured to separate a liquid phase from crankcase gases of an internal combustion engine using a rotor. The housing includes a housing body forming a separation chamber, an opening in the housing body, a bearing retainer arranged at the opening, and a bearing inserted into the bearing retainer. The bearing is configured to receive a rotor shaft extending into the separation chamber. The bearing retainer includes a bearing seat portion provided with a number of plastically deformed zones retaining the bearing in the bearing retainer. A centrifugal separator and a method of retaining a bearing of a rotor shaft in a housing for a centrifugal separator are also disclosed.

Self-cleaning centrifugal separator
A centrifugal separator is provided with a base and a substantially vertical spindle upstanding from the base. A rotary vessel is mounted on the spindle. A housing is connected to the base and encloses the rotary vessel. A liquid supply duct supplies a liquid to be filtered to the rotary vessel. The rotary vessel has an open top and an upper edge at the open top. The rotary vessel is provided with a filter material and has a weir arranged at the upper edge, wherein the filter material extends upwardly to the weir. The housing has a passageway adjacent to the weir and the passage way communicates with the weir to enable discharge of waste material that is contained in the liquid to be filtered and does not pass through the filter material during supply of liquid to be filtered to the rotary vessel and rotation of the rotary vessel.
