摘要： Various example embodiments relate to a system that includes a nozzle. A dosing line is connected to the nozzle and a fuel dosing module. The fuel dosing module is in fluid communication with the dosing line and includes an outlet in fluid communication with the dosing line. An air inlet is positioned upstream of the outlet and is configured to receive air. A fuel inlet is positioned upstream of the outlet and is configured to receive fuel. A fuel valve is positioned upstream of the outlet and downstream of the fuel inlet and is configured to control the flow of fuel. The fuel dosing module is configured to combine the fuel and the air upstream of the outlet and downstream of the fuel valve to generate an air-fuel fluid, wherein the air-fuel fluid removes particles from the nozzle.

摘要： A valve unit has a plate-shaped valve body with a closure section and a connection section. The valve body has a cutout surrounded by a frame. The closure section has a closure tab that, beginning at a first fastening section at the frame, projects into the cutout. The connection section, beginning at a second fastening section at the frame, projects into the cutout and has a contact tab and a fastening point. The first and second fastening sections are arranged opposite each other at the frame along a longitudinal axis of the valve body. A filter head for the valve unit has a valve seat for a seal body of the closure section of the valve body. A fastening pin of the filter head fastens the connection section of the valve unit. A contact region of the filter head contacts a positioning region of the valve unit.

摘要： A filter device includes in a filter housing a hollow cylindrical filter element having frontal end plates, a flow opening being made in one of the end plates. In order to interlockingly secure a pipe connection piece that communicates with the flow opening, a cover has a radial collar which forms an axial stop for the pipe connection piece.

摘要： A filter module for filtering fuel in an engine system includes a primary filter, a secondary filter, and a module housing. A drain valve is movable between a closed position blocking a drain port in the module housing, and an open position. A service valve assembly is positioned at least partially within a cross passage in the module housing and adjustable from a closed configuration blocking a primary-side fuel passage from a secondary-side fuel passage in the module housing, to an open configuration, to drain fluids from the filter module by way of the single drain port.

摘要： A fluid filter is mountable on a connection flange having a central stand pipe and an exchangeable filter insert. The insert has a hollow cylindrical filter material body with two end plates on its end faces and is mountable on the stand pipe. A cup-shaped screw housing of the filter can be screwed to a free end of the stand pipe, and supports a seal on a free edge thereof, via which the screw housing is sealable against a connection flange sealing surface when mounted. The filter has a first arrangement on an end face area to center the end face area to the flange. The filter insert has a second arrangement on the end face area outer periphery for centering the screw housing free edge relative to the connection flange sealing surface. The second arrangement interacts in a centering manner with the screw housing free edge when installed.

摘要： A fuel filter is provided which comprises a manifold, a connector element, a filter bowl, a filter element, an inlet shutoff valve, an outlet shutoff valve, an inlet port, an inlet passage, an outlet port, an outlet passage and a relief valve in which the connector element is fixed to the manifold, and the filter bowl is reversibly fixed to the connector element. The filter bowl is adapted to reversibly receive the filter element and is so configured that when the filter element is located within the filter bowl and the filter bowl attached to the connection element the filter element divides the space defined by the connector element and filter bowl into an inlet filter chamber and an outlet filter chamber. The inlet port mouths through a surface of the manifold, and the inlet port and inlet filter chamber are in fluid communication via the inlet passage.
