The invention relates to an end plate for filter material (10) for filtering a liquid, particularly a hydraulic oil, having a through opening (11) for filtered liquid, which is surrounded by a sealing ring (20) for a connecting piece, and a cover (12) for the filter material (10). The invention is characterized in that the sealing ring (20) delimits a free space (13) for accommodating an anti-rotation lock (14) of a switch (15) and/or a bypass valve (16) of a filter system (30). Furthermore, the invention relates to a filter element, a filter system and a method for filtering liquid.

A filter for hydraulic fluids including a container defining inside a housing compartment fluidically communicating with an inlet and an outlet associated with and a filtering cartridge, and partitioning the compartment in first and second chambers. The cartridge is configured and positioned for determining the filtering of the hydraulic fluid from the inlet which flows from the first to the second chambers. The container exhibits an engagement portion projecting inside the housing compartment and defining a collar having an outer coupling lateral surface, while the filtering cartridge exhibits a respective engagement portion defining a respective collar exhibiting an inner coupling lateral surface configured for engaging outside the outer coupling surface of the container. The coupling surface of the engagement portion of the container exhibits a polygonal cross-section; the inner coupling surface of the engagement portion of the cartridge is at least partially countershaped to the coupling surface of the container.

The invention relates to a high-pressure hydraulic fluid screening element (1) for inserting into a hydraulic line or into a hydraulic connection of a hydraulic device, having an annular main body (2), which is aligned with respect to its axis of rotation (9) in a longitudinal direction (5). The outside diameter of the main body (2) is greater than its axial length. The inner cross section of the main body (2) is covered over by a screening region (3), which is provided with a multiplicity of apertures (4). In this case, the main body (2) and the screening region (3) are produced integrally by the powder injection-molding process.

The present invention provides a device for controlling the exhaust of a vehicle's pneumatic system, herein after referred to as the exhaust controller. The exhaust controller may comprise at least one intake opening operable to receive compressed exhaust air via a pneumatic line and direct it towards at least one exhaust opening operable to redirect and effectively neutralize the force of the exiting air such that prevents the formation of a dust cloud. The intake opening may further comprise an adjustable connector operable to interface with a pneumatic line and create an adjustable seal with the intake opening and the pneumatic line. The pneumatic line may be an exhaust valve of the pneumatic system or airline tubing in fluid communication with the exhaust valve. The exhaust valve may be part of an air compressor, air reservoir, air brake, or an air suspension system.

A pneumatic control system includes a manifold that defines: a channel for conveying a fluid, a discharge port, a drain port, and an expansion chamber defining a chamber axis. The discharge port defines a flow axis extending between a first end and second end and a receiving region at the second end. The pneumatic control system also includes a filter assembly with a filter member disposed in the expansion chamber, and an actuator configured to selectively control fluid communication between the channel and the discharge port. The chamber axis is substantially coplanar with the flow axis. A filter cap assembly includes a filter cap body enclosing an end of the expansion chamber and selectively removable from the manifold to provide access to the filter assembly. A purge valve body is configured to selectively control fluid flow between the expansion chamber and the drain port.
