  • Patent number: 11862449
    Abstract: A system for sampling a liquid includes a sample fluid conduit including a membrane having pores. The membrane prevents the passage of the sample liquid through the pores at a first pressure of the sample liquid in the sample fluid conduit. A surface sampling capture probe has a distal end. The capture probe includes a solvent supply conduit and a solvent exhaust conduit. A solvent composition flowing at the distal end of the capture probe establishes a liquid junction with the membrane and establishes a second pressure within the liquid junction at the membrane. The second pressure is lower than the first pressure. Sample liquid will be drawn through the pores of the membrane by the second pressure at the liquid junction. A method for sampling a liquid and for performing chemical analysis on a liquid are also disclosed.

  • Patent number: 11571643
    Abstract: An exchangeable filter element of a liquid filter has a filter medium surrounding circumferentially a virtual axis of the filter element. A discharge closure element is arranged eccentrically at an axial end face of the filter element. The discharge closure element closes off a discharge opening of a discharge channel of the filter housing when the filter element is installed in the filter housing. The discharge channel serves to empty liquid from the filter when the filter element is removed. The discharge closure element has a limited circumferential expansion with respect to the virtual axis. The discharge closure element has a closure surface arranged at an axial end face of the discharge closure element. The closure surface is at least partially axially oriented. The closure surface rests so as to seal axially at a sealing section of the filter housing that surrounds the discharge opening of the filter housing.

  • Publication number: 20110084016
    Abstract: A filtration assembly is provided for a fluid flowing in an engine or an apparatus that includes a tank on which a central tube is mounted for interaction with a filtration cartridge including an upper flange and a lower flange between which extends a filtration medium. The central tube is permanently mounted on a bearing member connected to the tank. The central tube bears a first seal and a second seal. The cartridge has a collar forming an extension of the lower flange, the collar being adapted for interaction with the first seal on the central tube in order to ensure tightness between the tube and the cartridge. The second seal is adapted for interaction with the bearing member and/or the collar in order to ensure tightness between the tank and the tube.

  • Patent number: 7896166
    Abstract: A compact filter element in which the end faces of a plurality of nonwoven filter layers (3) are fixedly integrated into a cover (4) and in which the oncoming flow of fluid to be filtered is deflected in the cover (4) in such a way that the fluid flows respectively into every second or alternating area between two adjacent nonwoven filter layers (3) and flows through the nonwoven filter layers (3) into the intervening spaces between the spaces between filter layers in to which it initially flows, from which intervening spaces it exits the filter element.
