Abstract:
A filter unit (40) includes a top plate (46), a bottom plate (48), and a filter medium (42). The top plate (46) is disposed at a first end (108) of the filter unit (40). The bottom plate (48) is disposed at a second end (110) of the filter unit (40). The bottom plate (48) includes a threaded filter portion (116) and a valve shaft (138). The threaded filter portion (116) has external threads and the valve shaft (138) extends from the threaded filter portion (116) along an axis of elongation of the filter unit (40). The filter medium (42) is disposed between the top plate (46) and the bottom plate (48).
Abstract:
The invention relates to a liquid filtering device comprising a filter element (4) axially insertable into a filter housing (2, 3), wherein said filter element (4), in the mounted position thereof, closes a reflux locking device (7) for a filterable crude liquid by at least one seal which is maintained in the filter housing (2, 3) and embodied in the form of a reflux locking membrane (7; 10). Said reflux locking membrane (7; 10) is applied to the function carrier (5; 8; 16) of the filtering device in such a way that the axial or radial sealing thereof on the clean and crude sides is obtained.
Abstract:
Known filters for central and district heating systems must be cleaned frequently and further there is risk that the filter may clog completely. The invention solves this problem and allows in addition removal and cleaning of the filter unit while the heating system is still operational. When the pressure drop is being too high a spring loaded valve (9) permits the circulating water to pass through a channel (7) by-passing the filter unit (3). When the valve (5) is turned in its blocking position then the filter unit (3) is unpressurized as a one-way valve (6) prevents pressure from the outlet side. In this position the filter unit may be removed and the circulation is maintained through the channel (7).
Abstract:
A filter element (16) may include a tubular element (26) defining an internal space (32), and a retainer element (34) associated with a first end (28) of the tubular element (26), wherein the retainer element (34) is configured to be coupled to a first housing (14). The filter element (16) may also include a valve seat member (36) in the internal space (32). The valve seat member (36) may include a valve seat aperture (38) configured to provide a fluid seal with a valve poppet (40). The filter element (16) may further include first and second end caps (42, 46) associated with ends (28, 30) of the tubular element (26). The filter element (16) may also include filter media (50) around the tubular element (26), and the second end cap (46) may be configured to provide a fluid seal (76) between the filter element (16) and a drain passage (24) in a second housing (18), such that as the filter element (16) is separated from the second housing (18), fluid flows from the filter element (16) into the drain passage (24).
Abstract:
A filter (101) for a fluid injection valve (100) is specified. The filter (101) comprises a filter sleeve (102) and a fastening element (120). The fastening element (120) comprises a fitting portion (122) for fastening the filter in the fluid injection valve (100) and a connection portion (121) mechanically interacting with a first part (103) of the filter sleeve (102) for connecting the filter sleeve (102) and the fastening element (120). The filter sleeve (102) comprises a second part (104), the second part (104) being arranged inside the fastening element (120) and being disposed at a distance (116) from the fitting portion (122) of the fastening element (120). Further, a fluid injection valve (100) and a method for producing the filter (101) are disclosed.
Abstract:
The present disclosure relates to a fluid filter system including, but not limited to, structure for enabling a filter cartridge to be installed and removed from a manifold with a straight line push/pull motion, a latching mechanism and a water manifold, the latching mechanism providing a unique mechanism interface between a manifold and a filter cartridge, the latching mechanism providing a compact and simple mechanism between the manifold and the filter cartridge that significantly reduces the installation and removal force previously found with fluid filtration cartridges by including a low force filter cartridge installation and removal mechanism for utilization by the end consumer and the manifold assembly includes an inlet and an outlet port, the manifold assembly having structure for maintaining a substantially constant volumetric cavity of the fluid filtration system that contains fluid during installation and operation of the filter therein and removal of the filter therefrom and that has an automatic shut-off system, as the inlet water pressure increases past a predetermined desired maximum system operating pressure, the inlet water will automatically be shut-off, i.e., will not flow into (or out of) the filter cartridge.
