摘要:
An air intake filter for the internal combustion engine of a motor vehicle in which a substantially cylindrical housing contains an annular filter insert through which the air flows radially from the outside to the inside. At one end of the housing an end opening of the filter insert sealingly engages a tubular projection which communicates with the clean air outlet so that the filter insert is centered within the housing. At its opposite end, the filter insert is closed by a cover and is provided with fastening elements which engage in the junction between the housing and the cover, so that the fastening of the cover to the housing simultaneously serves to axially and radially secure the filter insert in place. Alternatively, the cylindrical housing may be formed of two, semicylindrical half-shells, and the filter insert may be provided with an annular bead which mates with a corresponding indentation in the housing to assure proper installation of the filter insert.

An intake air filter for an internal combustion engine is disclosed which includes a housing having a raw air inlet for unfiltered air and a clean air outlet for filtered air and first and second annular filter inserts disposed concentrically one inside the other within the housing through which air flows radially from the outside to the inside, the first filter insert being an outer filter insert, and the second filter insert being a safety cartridge disposed within the first filter insert, the second filter insert being closed at one end with a cover plate; the other end of the second filter insert facing the air outlet, and the second filter insert being secured to the housing by a screw thread adjacent the air outlet.

A suction air filter for a combustion engine includes a filter housing for receiving a filter insert and an attachment housing to which the filter housing is attached. The filter housing has a coupling end for coupling with a corresponding coupling end of the attachment housing. The suction air filter has an unfiltered air intake and a pure air outlet. A plurality of cam members are mounted on the outside of the filter housing near the coupling end thereof, and a plurality of cam elements are mounted on the outside of the attachment housing near the coupling end thereof. A rotatable coupling ring is mounted to receive the coupling ends of the filter housing and the attachment housing, and the coupling ring carries wedge members which are engagable with the cam members and the cam elements to releasably couple together the coupling ends of the housings. Dust protection shoulders or labyrinth seals are provided on both sides of the coupling ring to prevent dust from penetrating in the closure area of the attachment portion and the housing. A turning of the coupling ring effects a fixing of the filter housing to the attachment housing.
摘要:
A filter system for filtering the air intake of an internal combustion engine including a housing having a bottom half and a cover half, at least two filter inserts each consisting of pleated filter paper or filter batting, and a circumferential gasket. The two filter inserts are connected by a junction strip which simultaneously seals the raw air chamber from the clean air chamber between the two filter inserts.
摘要:
A method for generating a network, in particular a telecommunications, water, long-distance heat supply, or power network, the network connecting all users to a main distribution node depending on the existing or definable local needs and requirements of the individual users. A graph is generated which is composed of edges and nodes. The graph includes all technically feasible and/or definable transmission paths of the network. The length and direction of the edges are derived from the real topography of the street segments and definable cable paths of the territory to be supplied by the network. The nodes form the intersections between the edges or streets and/or cable paths. The users are assigned to the graph in such a way that each user is connected to the closest edge or the closest node of the graph by an additional service edge. A tree structure is created by removing unnecessary edges from the graph in such a way that the service edges, edges, and nodes of the tree structure form only one connection between the main distribution node and each user. The load of the edges in the tree structure is determined depending on the needs and requirements of the users.
摘要:
A fluid filter, particularly for cleaning lubricating oil for internal-combustion engines of motor vehicles, which includes a filter housing 10 with a screw cap 11 and an annular filter element 12 inserted into the filter housing 10. The filter element 12 is pushed onto a supporting tube 15, which in turn is locked to the cap 11 or the bottom of the filter housing 10. Arranged on the cap or on the bottom are detent tongues 18 which engage with detent tongues 20 of the supporting tube 1B. Guiding surfaces 21 are provided for the detent tongues of at least one element.
摘要:
An air intake filter for internal combustion engines has a flat, replaceable filter insert 20, through which the air flows transversely in operation, and which has a gasket 22 disposed on the periphery for sealing at the face side against a ledge 15 of the filter housing 11. The insert can be inserted into the filter housing through a narrow side, the sealing pressure being produced by a cover 50 which has two sliding wedges 51 and 53. To bring it about that, when the sealing pressure is applied, the gasket 22 will not be shifted laterally with respect to the ledge 15 of the filter housing 11, the cover, which is in the form of a substantially open frame, replaceably accommodates the filter insert. The cover is provided with cams 40 and 41 which serve to fix the frame 30 in an extended position during the replacement of the filter insert. Also the lateral walls 25 and 26 of the filter housing and the lateral walls 45 and 46 of the frame 30 are inclined wedgewise to avoid large frictional forces between the adjacent surfaces when the filter is installed and removed.

The invention concerns an intake system, in particular an intake pipe of thermoplastic plastics for the intake air of an internal combustion engine with in particular cylinder rows arranged in a V-shape. The intake system comprises at least two elements (10, 14), the first element (10) having a substantially closed shape and simultaneously forming the lower half-shell of the intake pipes. The second element (14) is designed as the upper half-shell of the intake pipes and is connected to the first element (10) by the plastics welding technique.
摘要:
An air filter, particularly for the intake air of an internal-combustion engine, including a housing 13, an air filter insert 16 arranged in the housing, and a cover 10 closing off the housing 13. The air filter insert 16 is essentially a rectangular cartridge which has a surrounding seal 18. This seal 18 is clamped in between the housing 13 and the cover 10 in such a manner that it separates the unfiltered-air space from the filtered-air space. In addition, clamps 19 are provided which fasten the cover and the housing to each other and the filter cartridge is simultaneously secured in the housing. Direct supporting contact between the cover 10 and the housing 13 occurs only adjacent the clamps 19, and simultaneously the seal has a very low Shore hardness. As a result, the cover no longer rests as previously on the housing over the whole length of the seal, but only in the area of the clamps.
摘要:
A gas laser has (1) a reflecting body with a reflecting surface, (2) excitation space structure cooperative with the reflecting body for defining an excitation space which is open opposite the reflecting surface of the reflecting body, (3) devices for lasingly exciting a gas in the excitation space and (4) a mirror assembly. The mirror assembly has a mirror having a reflecting surface facing the opening in the excitation space. A radial flange is about the mirror with the reflecting surface of the mirror on one axial side of the radial flange. At least one spacer and, preferably three, circumferentially-spaced bars project from the excitation space structure and engage the radial flange substantially axially for supporting it at least one of axially slidably and tiltably. Bellows sealingly connect the one axial side of the radial flange to the opening of the excitation space structure and its other axial side to a backplate immovably connected to the spacer bar on the other axial side of the radial flange. Preferably, the reflecting body is another such mirror assembly.
