Abstract: Provided is a cartridge assembly having first and second cartridges sealed by an interface member having a first sealing member along a radially outer surface thereof having a non-planar geometry around the outer surface and a second sealing member along the radially outer surface having a non-planar geometry around the outer surface. The sealing members may each have a repeating, undulating, non-planar geometry around the outer surface. The cartridges have ends with matching geometries to allow the cartridges to engage in surface-to-surface relation around their entire extents to create with the interface member an air tight seal.

Abstract: A filter for hydraulic fluids including a container defining inside a housing compartment fluidically communicating with an inlet and an outlet associated with and a filtering cartridge, and partitioning the compartment in first and second chambers. The cartridge is configured and positioned for determining the filtering of the hydraulic fluid from the inlet which flows from the first to the second chambers. The container exhibits an engagement portion projecting inside the housing compartment and defining a collar having an outer coupling lateral surface, while the filtering cartridge exhibits a respective engagement portion defining a respective collar exhibiting an inner coupling lateral surface configured for engaging outside the outer coupling surface of the container. The coupling surface of the engagement portion of the container exhibits a polygonal cross-section; the inner coupling surface of the engagement portion of the cartridge is at least partially countershaped to the coupling surface of the container.

Abstract: A membrane casing that watertightly houses a membrane element for filtering raw water includes a tubular casing main body, a lid body, and a pressing mechanism. The casing main body houses a membrane element. The lid body fits an opening end of the casing main body and is movable in the axial direction of the casing main body while maintaining the attitude and while securing watertightness with the casing main body. The pressing mechanism and presses the lid body to press and hold the membrane element housed in the casing main body. The membrane casing has a simple configuration capable of watertightly securing using a predetermined pressing force by accommodating variations in size of the membrane element, even if the membrane casing cannot be formed into a cylindrical shape.

Abstract: A filter device has a filter housing (1) receiving a filter element (11) defining a longitudinal axis and being in the form of a filter cartridge. An end cap (19) forms an enclosure for the relevant end rim of the filter material (23, 25). The end cap fixes the position of the filter element (11) in its functional position by being on an element receiver (13) that interacts with the bottom part (7) of the filter housing (1). The element receiver (13) and the assigned end cap (19) of the filter element (11), on their parts (17 and 15) coming into engagement with one another in the functional position of the filter element are provided with shaped irregularities matched to one another to enable the engagement in a positional relationship directed towards one another.
