Abstract: A filter device with a filter body (1) has a filter bowl (3) and a filter head (5) formed by a removable locking piece of the filter bowl (3). The filter head (5) has a connection point (15) for an unfiltrate flow and a connection point (27) for discharging a filtrate flow. A filter element (7) containing filter material (11) is connected between the connection points (15, 27) and is disposed inside the filter bowl (3) for the filtration of the unfiltrate, specifically for particle contamination. A flow directing device (33) directs the unfiltrate flow to the surface sections of the filter material (11) of the filter element (7) to provide a filtering action when the device is in operation. The flow directing device is a molded component (33) that belongs to the filter head (5) and to which a fluid flow is applied.

Abstract: A filter device has a filter element (3) received in a filter housing (1) and has a holding device (19) for detachably fixing the filter element in the filter housing (1). Corresponding threads (23, 33) form a screw connection between a housing cover (5) of the filter housing (1) and the filter element (3). A sealing device (29, 35) imparts a sealing action between the filter element (3) and the housing cover (5). The screw connection is formed by threads (23, 33) situated in the interior (22) of the filter element (3). The thread (33) assigned to the filter element (3) is situated on a connecting pipe piece (31) that, as a constituent part of an end cap (17) of the filter element (3), extends into the inner filter cavity (22) of the filter element (3). The thread (23) assigned to the housing cover (5) is situated on a receiving pipe piece (21), which can be screwed to the connecting pipe piece (31) of the filter element (3). The receiving pipe piece is formed by a separate component in the form of a pipe piece (21) attached to the housing cover (5).

Abstract: A filtering apparatus includes a pot-type filter housing (10), a filter element (28) accommodated in the housing, a holding mechanism (38) disposed in the filter housing (10) to removably fix the filter element along its longitudinal axis, and a sealing device (60) that seals between a lid (20) of the filter housing (10) and the filter element (28). The holding mechanism (38) is provided with cooperating holding elements embodied on the interior face of the filter housing (10) as well as on the filter element (28). The filtering apparatus dispenses with the need for O-seals that are known in prior art and extend in a radial direction between the filter element and the filter head as a housing lid because the sealing device (60) encompasses at least one sealing edge (62) or sealing surface placed parallel to the longitudinal axis in a radial direction and seals under the effect of the pressure applied it by the holding mechanism (38). The invention further relates to a filter element that is to be used in such filtering apparatus.

Abstract: A filter device has a filter housing (1, 3) releasably accommodating one filter element (15) and has a housing pot (1) surrounding the filter element (15) and a removably attachable housing head (3) with fluid passage (39) for the discharge of filtrate. A valve device in the fluid passage includes a closing body (53) blocking the discharge flow in its closed position and facilitates the discharge flow in its release position. A locking device includes a blocking member (57) locking the closing body (53) in its closed position. The blocking member (57) can move out of its locking position into its unlocking position by a control element (81) on the filter element (15). When the filter element (15) is situated in its functional position in the housing pot (1), the control element impacts the blocking member (57) as the housing head (3) is attached to the housing pot (1) to move the blocking member axially to its unblocking position.
