An oil separator with a housing, in which is rotatably mounted a rotor containing a drive element, an oil separating element and a shaft for driving the oil separating element of the rotor via the shaft of the rotor around the shaft axis. At least one element of the rotor is seated in such a way that it is displaceable via an actuator element axially from a first inoperative positive to a second operating position.

A gas-water separation system may be used for removing water from a wet gas compressed in a water-injected contact-cooled gas compressor. The gas-water separation system may include a tank constructed to hold a quantity of water; a heat exchanger coupled to the tank and constructed to extract heat from the water to chill the water when the water is present within the tank; an inlet port constructed to inject a flow of the wet gas into the chilled water when the water is present within the tank, the chilled water being operative to condense water vapor from the wet gas and reduce the dew point of the wet gas to yield a chilled compressed gas; a biological control system constructed to suppress biological activity in the tank; and a discharge port operative to discharge the chilled compressed gas.

A centrifugal separator for separating blow-by gases into cleaned air and liquid for recirculation through an engine.

Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shall forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

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.

A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine assembly positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet. The fluid causes the turbine assembly to rotate about a center rotational axis within the housing. The turbine assembly comprises a first turbine portion and a second turbine portion that are separately formed from each other and attachable together. The first turbine portion comprises a plurality of first vanes and the second turbine portion comprises a plurality of second vanes.

A filter assembly has a housing with a housing inlet and a drain. A rotary vessel is rotatably mounted within the housing and has a rotary vessel inlet and a rotary vessel outlet. Fluid exiting the rotary vessel outlet exits the housing through the drain. A valve assembly moveable between a closed and an open configuration is provided. When closed, the valve assembly fluid-tightly seals rotary vessel inlet from housing inlet. When open, the rotary vessel inlet is in fluid communication with the housing inlet such that fluid flowing into the housing inlet passes into the rotary vessel inlet. The valve assembly is moveable from closed to open configuration when a pressure of fluid flowing into the housing inlet exceeds a threshold pressure. The filter assembly has a fluid passageway permitting air flow into the rotary vessel through the rotary vessel inlet when the valve assembly is closed.

A separation assembly comprises a housing and a bearing plate assembly. The housing contains a turbine assembly and a rotor portion and defines a fluid inlet and a fluid outlet. The bearing plate assembly is adjustably attachable to the housing and defines a drive jet that directs fluid from the fluid inlet to the turbine assembly. The bearing plate assembly is mountable to the housing in multiple different orientations such that the relative position of the fluid inlet of the housing and the drive jet of the bearing plate assembly is adjustable.

A centrifugal separator includes a frame and a drive member configured to rotate a rotating part in relation to the frame around an axis of rotation. The rotating part includes a centrifuge rotor closing a separation chamber. The separation chamber includes a stack of separation discs arranged coaxially around the axis of rotation at a distance from each other such as to form passages between each two adjacent separation discs. The stack of separation discs includes a first type of separation discs having an outer diameter of A or below, and at least one separation disc of a second type having outer diameter B or above, wherein diameter B is larger than diameter A. At least one of the separation discs of the second type is arranged at a position in the disc stack that is within the upper 15% of the total number of separation discs and at least one of the first type of separation disc is arranged axially above the uppermost separation disc of the second type.

A separator for removing contaminants from a circulating liquid, preferably a contaminated oil, by use of centrifugal motion wherein a cylindrical chamber is mounted about a spindle serving as an axis of rotation. In-flowing contaminated liquid to be treated enters the cylindrical chamber and the base of said chamber and is directed onto distribution disk wherein it impacts a plurality of drive surfaces that impart a first source of rotational motion to said chamber. The in-flowing oil to be treated is directed against the inner wall of the cylindrical chamber, thus causing contaminant to adhere to the inner wall. As the thickness of contaminant increases on the inner wall of the chamber, the rotational speed of the chamber is reduced until it reaches a predetermined threshold speed causing a sensor to activate a signal indicating that the separator needs to be cleaned of contaminant. There is also provided a porous material at the exit where treated liquid exits and which, after a period of time, will become blocked and thus also acting to slow the rotational speed of the chamber.
