  • Publication number: 20240091791
    Abstract: A centrifugal separator for separating a liquid phase from a crankcase gas includes a housing, a separation chamber inside the housing, a rotor shaft, a rotor connected to the rotor shaft, a bearing arranged at an end portion of the rotor shaft, and a liquid outlet for the separated liquid phase. The end portion of the rotor shaft extends through the bearing outside the separation chamber. A ring-shaped sealing gap is formed between the housing and a member connected to the rotor shaft outside the separation chamber. The liquid outlet is arranged, seen in relation to the axial direction, radially outside the bearing and radially inside a radially outer end of the ring-shaped sealing gap.

  • Patent number: 11351557
    Abstract: 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.

  • Patent number: 10967388
    Abstract: A centrifugal separator for separating a liquid phase from crankcase gases of an internal combustion engine includes a separation chamber, a rotor shaft, a rotor inside the separation chamber, an inlet for crankcase gases, a gas outlet, and a liquid outlet for separated liquid phase. The centrifugal separator also includes a liquid outlet chamber, a check valve, and a rotating member. The liquid outlet chamber forms an individual chamber and is arranged in fluid communication with the separation chamber via a liquid passage. The rotating member is connected to the rotor shaft and is arranged inside the liquid outlet chamber. The liquid outlet forms an outlet of the liquid outlet chamber. The check valve is arranged in the liquid outlet.

  • Patent number: 6962244
    Abstract: The present invention concerns a brake mechanism of a disc brake received in a caliper and a method for controlling the force amplification for the brake mechanism. The brake mechanism comprises a lever actuated by a brake actuator. The lever is acting on a cross bar by means of an intermediate part. The lever and the intermediate part have a line of contact moving along a circular arc during an application stroke of the brake mechanism. The cross bar of the brake mechanism is closely guided and is only moveable in the thrust direction and in the tangential direction of the brake disc. The force amplification of the brake mechanism is adapted to the force characteristics of the brake actuator.

  • Patent number: 6668981
    Abstract: The present invention concerns a disc brake having a brake mechanism. The disc brake comprises a caliper (16) reaching over a brake disc and having a cavity for receiving the brake mechanism. The brake mechanism comprises a bearing bracket (30) received from the inside in an opening (17) of the caliper (16) in the side wall furthest from the brake disc. The brake mechanism comprises an adjuster mechanism (23) an adjustment shaft (40) and a reset shaft (41). Means (24) are provided for transferring movement between the adjuster and reset shafts (40, 41). The adjuster mechanism is actuated by a lever pin (43) on a lever (31) of the brake mechanism and is received in the bearing bracket (30) at assembly.
