摘要:
A filter having a filter element disposed in a filter housing; the filter element being formed of a pleated filter paper or a nonwoven filter material and being of substantially planar or flat configuration. Sealing elements in the form of a rolled seal are provided on at least two lateral surfaces of the filter in order to seal the filter element in the filter housing.

A filter insert for the filtering of the fresh air supplied to a motor vehicle interior has an accordion-folded filter element which is self-supporting. Lateral strips coated with an adhesive are provided on the faces which extend on the left and on the right. On the faces which extend in parallel to the folding, angle strips are arranged whose first leg extends along at least three fold edges. The filter element is surrounded along the faces by a foamed-material sealing.
摘要:
A filter, especially for the interior ventilation of vehicles, including at least one filter body configured as a plate-like element and a frame surrounding the plate-like element, the frame being made from at least two frame parts joined together in the plane of the plate-like element.
摘要:
A support tube for a fluid filter, particularly a support tube made of synthetic resin material, which is made up of two substantially identical tube parts (3) each of which has at least one inlet opening (4), at least one outlet opening (5) and at least one radial sealing area (6) and/or axial sealing area (7), and at least one connecting region (8) which engages the other tube part to connect the tube parts and form an assembled support tube.
摘要:
A filter arrangement with a cellular structure in which a plurality of filter chambers extend in the direction of the medium to be filtered. There is a filter cloth or fabric attached to each of the two sides of a cell frame which closes the filter chambers on both sides. The filter chambers are each provided with a filling of predominantly active charcoal granules. To achieve a simple and advantageous structure of the filter arrangement, the cellular structure is in the form of a rectangular cell frame each with rectangular filter chambers, preferably made of synthetic resin. Appropriate, right-angled partition walls inside the cell frame and the installation of reinforcement members can result in filter chambers of optimum size.
摘要:
The mechanically driven pump is provided with a delivery chamber which communicates with an annular groove about a valve needle of the injection valve to deliver pressurized hydraulic medium to prevent an inflow of liquid fuel between the valve needle and the injection valve body. The hydraulic pressure medium of the mechanically driven pump also drives a reciprocating piston in the hydraulic pump used to pump the fuel to the injection valve and, thus, also provides a barrier to the passage of liquid fuel between the reciprocating piston and the surrounding wall of the pump.
摘要:
An air filter for an for an air intake of an internal combustion engine. The filter includes a housing with a raw air inlet and a clean air outlet and an annular filter element having a pleated filter medium disposed therein. At least one buttressing element is provided to support the filter medium at the clean air side. The buttressing element has a knife-edge buttress disposed on the housing that extends to a position of maximum flexure of the filter element. The knife-edge buttress is further provided with a support shoe disposed thereon such that the shoe supports the filter element.
摘要:
A filter element for an air filter, including a filter insert (2; 8; 10) and a seal (6) extending around the outer edges of the filter insert on the flat side thereof; the filter insert being folded in a zig-zag or pleated form and being composed of filter paper or filter fabric. The filter element (1; 7; 9; 10) rests against parts of a filter housing through the seal (6). The folded filter insert has a contour on one side which deviates extensively from a plane, at least in certain predetermined areas, thus creating a continuous zig-zag fold.
摘要:
A filter element having a first tube 2 and a second tube 3, the outer circumferential surface of the first tube 2 being surrounded by a nonwoven layer 4, and the second tube 3 surrounding the first tube 2. On the outer periphery of the second tube 3 there is a yarn and/or paper winding 5, and a shrink tube 6 presses the yarn and/or paper winding 5 against the second tube.
摘要:
An air filter for an internal combustion engine having a housing 10 with an air inlet 11 on the raw air side and an air outlet 12 on the clean air side. The air outlet has a tubular projection 27 extending into the housing 10 on which a filter insert 15 can be removably fastened. Air passes through the filter insert 15 radially from the outside in. To seal the filter insert 15 on the tubular projection 27, a radial gasket 23 is provided which has an attachment portion clamped by an inwardly extended flange on an end plate 19 of the filter insert, and which has a seal portion with a sealing area arranged adjacent the attachment portion.
