Abstract:
A filter device may include a ring filter element arranged in a filter housing in an upright manner. The ring filter element may have an upper end disc and a lower end disc. A dirt pot may have a water separator arranged therein and be provided on the lower end disc. The dirt pot may also have a protruding pin. A channel may be configured to receive the pin and be provided on at least one of a filter housing pot and a functional element. The filter device may be operational when the pin engages into the channel.
Abstract:
A coalescing agent for facilitating the separation of a non-aqueous phase from an aqueous phase of an aqueous medium, said agent consisting of particles of a polymeric foam material having: an IFD no. of 40 or higher (i.e. at least 40); a BR no. of 35 or higher (at least 35); a SF no. of 1.8 or higher (i.e. at least 1.8) and a density of 42 kg/m3 or less.
Abstract:
A liquid filter cartridge is provided. Preferred seal arrangements are provided, to provide for preferred axial load conditions, with respect to one or more of the end caps of the cartridge. Some cartridge configurations provided include no core structure or outer liner structure therein, to support axial load. Assemblies using the cartridge, and methods of assembly and use, are provided. The liquid filter cartridge can be a serviceable cartridge, or it can be retained permanently in a housing.
Abstract:
A liquid filter has a filter housing with a first thread and a drain passage. A filter element including a filter medium is arranged in the filter housing. A filter lid is provided with a second thread configured to engage the first thread for connecting the filter lid to the filter housing. The filter lid further has a filter by pass valve for bypassing the filter element when a pressure loss that is too high occurs when liquid passes through the filter medium of the filter element. First bayonet connectors are provided on the filter lid and second bayonet connectors are provided on the filter element for connecting the filter element to the filter lid by engaging the first bayonet connectors. A double-concentric seal is arranged on the filter element for closing off the drain passage.
Abstract:
A filter element includes filter media, first and second end caps, a latch arrangement projecting from the first end cap, a tubular neck extending from the first end cap and a valve head oriented within the first end cap aperture constructed and arranged to move between a position sealing the first end cap aperture and exposing the first end cap aperture. A filter assembly includes a filter element, as characterized herein, and including a filter base and a service cover. A method of servicing includes removing an old filter element, operably mounting a new filter element in a filter base including engaging a valve head against a spring member in the filter base, and operably mounting the service cover over the new filter element and filter base. A method of filtering includes directing liquid into a filter assembly, blocking a first end cap aperture by using a spring member in the filter base to urge the valve head against a rim of a tubular neck extending from the filter element, and directing liquid through the filter media to filter the liquid.
Abstract:
A filtration module is provided which includes a manifold (100), a filtration cartridge (104) and a bowl (102) that houses the filter cartridge. The filtration cartridge and bowl are connected to each other to form a unitary construction. The filtration cartridge and bowl are in fluid communication with the manifold in a manner which prevents mixing of a fluid feed to the module and a permeate removed from the module.
Abstract:
A filter arrangement for filtering liquids has a central tube and a first filter element flowed through in radial direction outwardly and disposed on the central tube. A downstream second filter element is disposed on the central tub and flowed through in radial direction inwardly. The first filter element is moveable along the central tube from a basic position into an extended position. In the basic position a connection between the inlet line and a clean side of the first filter element is provided by the first filter element. In the extended position a bypass between an inlet line and the clean side of the first filter element is provided to bypass the first filter element. A spring element, applying a restoring force in a direction of extension of the central tube, is arranged on the first filter element at a side facing away from the second filter element.
Abstract:
A device for treating water having a cartridge, which includes a container for receiving treatment means and a connecting head. Furthermore, a connecting device is provided, which is equipped with a holder, a valve device, and a locking device. The holder has at least one side wall, on which the inflow and outflow openings are disposed. The valve device has a valve element, which surrounds the connecting head at least partially and is disposed movably in the holder. The associated cartridge provides at least one inlet opening and at least one outlet opening on at least one side surface. The cartridge has at least one recess and/or a lug for the engagement of a locking element of a locking device of the connecting device.
Abstract:
A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is secured within the filter housing, wherein the non-return diaphragm is arranged on the functional carrier so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement.
