Abstract: A liquid filter in the form of a filter element or a filter cartridge provides torsion locking relative to a filter head when the housing of such filter is threaded onto a filter head. Many embodiments employ a filter that includes a nipple portion at a top end with the torsion lock detent provided outboard of the nipple portion or integrated into the nipple portion. Many embodiments employ a simplified shoulder transition region at the top end of a torsion locked filter element. Valve actuation and/or filter differentiation is used in some embodiments. Different torsion locking arrangements, deformable thread profiles and other liquid filter features are disclosed.

Abstract: A water filter system includes a removable filter unit having a body portion including a proximal end and a distal end. The proximal end is adapted to be inserted into a filter head assembly. A laterally extending key member is disposed on the body portion and adapted to engage a key slot in the filter head assembly. An engagement protrusion extends from the proximal end. The engagement protrusion includes a first portion that has a first radius of curvature and a second portion opposing the first portion that includes a second radius of curvature that is larger than the first radius of curvature.

Abstract: A top load liquid filter assembly includes a filter lockout mechanism to ensure that the filter base and cover are not connectable unless there is a proper filter cartridge installed therein. The filter system can also include an automatic drain mechanism and a cartridge retention mechanism. One example embodiment further includes an air bleed vent. A filter cartridge usable in the topload liquid filter assembly includes first and second protrusions and cover-gripper members. Methods of use, installing, servicing, and retaining can be practiced.

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.
