  • Patent number: 10960413
    Abstract: 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.

  • Patent number: 8506816
    Abstract: Water and fuel contaminating material may be removed from a stream operating engine. A suitable membrane material is supported in a suitable housing. At least a portion of the contaminated oil stream is flowed over one side of the membrane and water and fuel material diffuses through the membrane to its other side where they are gathered and removed from the housing. The water and fuel material may be recovered separately using different membranes or different regions of a membrane. They may be swept from the membrane and housing a flow of air for disposition outside the housing.

  • Publication number: 20130043173
    Abstract: The invention relates to a liquid filter, having a filter housing, which contains a receiving space for a ring filter element. The liquid filter further has a no-load duct, which is opened when the ring filter element is taken out. A pin is formed on a lower end disc of the ring filter element, the pin projects parallel to the longitudinal axis. A ramp is formed on the bottom of the receiving space. The ramp is matched to the pin in such a manner that, when the ring filter element is inserted into the filter housing, the pin slides downwards on the ramp and penetrates the opening of the no-load duct. A structure is in the receiving space, the structure allows functional insertion of the ring filter element if the ring filter element slides with its pin along the ramp until the pin penetrates the opening of the no-load duct.
