Abstract:
A liquid filter having a housing with a removable screw lid and an interchangeable filter unit, the housing having a discharge channel, wherein a closure valve which when installed is fixed to the housing, is axially adjustable between a closed position when the filter unit is installed and the lid is closed, and an open position when the lid is detached and the filter unit is removed, and wherein releasable coupling elements are provided between the lid or filter unit and the valve. The coupling elements engage to transmit torque and tensile forces, by rotation in the loosening direction of the lid, for as long as a seal of the valve which exerts a braking moment on the valve is located in the sealing seat. The coupling elements disengage when the seal has departed from the sealing seat and the valve is thereby freely rotatable about its longitudinal axis.

Abstract:
A locking-unlocking structure for guiding forward lifting of a lifting body lifted by repeating a pushing action is provided. The locking-unlocking structure includes an actuation guide unit provided at a center thereof therein with a stop groove to guide stop of a lifting body in a lifting state, having a lifting line and a falling line branching downward from the stop groove, and fixedly coupled to a fixing body, and an actuation unit comprising a lifting plate having a stop protrusion, which is mounted in the stop groove of the actuation guide unit or circulates along the lifting line and the falling line, and coupled to the lifting body movably left and right. The guide protrusion protrudes from the falling line of the actuation guide unit while being inclined downward along the falling line to block an entrance so that the stop protrusion of the lifting plate is prevented from entering the falling line when the lifting plate of the actuation unit is lifted. The guide protrusion is provided in an elastic member to be elastically actuated when the stop protrusion of the lifting plate falls along the falling line.
Abstract:
A filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, includes a filter housing (1) having a fluid inlet (51), a fluid outlet and at least one filter element (9). During the filtering process, fluid can flow through the filter medium (11) of the filter element from the unfiltered side (13) to the filtered side (19) of the filter medium. The filtered side surrounds an inner filter cavity (17). On one side of the filter medium (11), a water-separating device (26) and a separating region (27) for separated water are present. The filter element (9) has a passage (43) that forms a fluid connection to the filter cavity (17) and at least one water opening (47) that is open toward the separating region (27). The filter element can be fixed to an element receptacle (29) of the filter housing (1) and can be connected to a water collecting chamber (33). An adapter part (49) is provided at least as part of a fluid-conducting system, in which fluid paths separated from each other are formed. A first fluid path (59, 67, 61) leads from a fluid connection (51) of the housing (1) via the passage (43) to the inner filter cavity (17) of the filter element (9). A second fluid path (69) connects the respective water opening (47) to the water collecting chamber (33).
Abstract:
Liquid filters comprising a housing having a removable cover, a liquid inlet, an outlet, a replaceable hollow cylindrical filter material insert, and a filter bypass valve comprising a valve seat arranged on the filter insert and a valve body that interacts with the valve seat and is biased in the closing direction. Two radially spaced closed sealing contours are provided between the valve seat and the valve body. At least one bypass channel, connecting the unfiltered and filtered side of the filter while bypassing the filter insert, passes through the valve seat between the sealing contours. The valve body is movably guided in the housing on a housing part, the two sealing contours are offset from each other in the axial direction, and the valve body has a corresponding conical or tapered or dome-like shape in the sealing area of the valve body that interacts with the sealing contours.
Abstract:
A fluid filter comprising a housing, a releasable cover and a replaceable filter having a filter body and two end plates. The filter is placed on a housing standpipe which has on its free side, facing the cover, an axially displaceable endpiece. The endpiece is preloaded in the expulsion direction and in that position is blocked by a locking system against insertion which prevents the cover from connecting with the housing. An unlocking device guided by the filter unlocks the locking system and allows insertion of the endpiece. The locking system is formed by locking tabs which are radially movable, and each have a locking face facing in the axial direction. The tabs are preloaded in the locking direction and each lock the endpiece in its expelled position against axial insertion relative to the standpipe. The tabs can be radially moved into their unlocking position by the unlocking device.
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 water filter includes a filter unit having a body portion adapted to be rotatingly received into a filter head assembly. An engagement protrusion extends from the body portion and is adapted for reception in a complementary receiver in the filter head assembly. An electronic device is disposed on the filter unit having a memory storage unit. A laterally extending key member is disposed on the body portion between the first engagement surface and the second engagement surface. The laterally extending key member is adapted to reposition an interference member from an interference position, whereby the body portion can be fully inserted into the filter head assembly to a non-interference position, whereby the body portion can be fully inserted into the filter head assembly.
Abstract:
A liquid filter with a replaceable filter insert and a housing having a raw liquid inlet, a central clean liquid outlet, and an eccentric liquid discharge channel. A standpipe extends above the liquid outlet and receives the insert. The insert has an eccentric closing pin. A first positioning arrangement is arranged on the clean liquid outlet and a lower end region of the standpipe so that, when the standpipe is plugged into the clean liquid outlet, the standpipe is guided into a particular position relative to the filter housing. A second positioning arrangement is arranged on the standpipe and the insert so that, when the insert is plugged onto the standpipe, it is guided into a particular position relative to the standpipe. The positioning arrangements are matched to one another so that the closing pin on the insert enters into engagement with the discharge channel in the filter housing.
