Abstract: A filter device has a filter housing (14) with a housing pot (12), which accommodates a replaceable filter element (16) and is closed by a removable lid part (32). The element material (20) of the filter element (16) separates an unfiltrate chamber (22) from a filtrate chamber (18, 43). A measurement sensing device (108) senses pressure values from at least one of the chambers (18, 22, 43), is disposed on a lid inner side (45) of the lid part (32), is at least partially guided in the lid part, and projects into the filter housing (14). At least parts of a measurement value evaluator (78) are connected to the measurement sensing device (108) and are disposed on the opposite lid outer side (42) facing the environment.

Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: A filter holder has an assembling base, a trigger component, and a body. The assembling base includes a mounting portion and a body holder having a connecting bole, a slit, a blocking end, and an engaging groove. The trigger component is connected to the body holder. The body is rotatably connected to the assembling base and has a cap, a connecting tube inserted into the connecting hole of the body holder, and a locking rib able to be located in the slit and the engaging groove. The trigger component is pressed away from the slit to drive the body holder to release an engagement between the engaging groove of the body holder and the locking rib of the body.

Abstract: A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.

Abstract: A filtering system (10) includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter (14) for coupling the filter unit to the receptacle, and also includes a base (12) having a cradle (26) for receiving the filtering apparatus and a base vacuum delivery port (28). The adapter includes an adapter vacuum receiving port (22) coupled to the vacuum delivery port for driving the liquid through the filter and—as filtered liquid—into the receptacle. The cradle and the adapter have an interlocking mechanism (52, 54) that locks the filtering apparatus to the cradle in a locking position in which the vacuum receiving port is sealingly coupled to the base vacuum delivery port. The base vacuum delivery port has a vacuum valve (30) constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.
