  • the cover 20 is dimensioned so that it is in the inserted into the connection console 1 state ( FIGS. 1 . 12 and 13 ) at least not to the sides and to the front (area of the protective wall 22) protrudes.
  • the lid is free of projections with respect to the frame 2 to the sides and to the front or in the main working direction Y. This ensures that the cover 20 is protected against damage and / or a change in position with respect to the receiving space 10, for example when the rammer 50 tips over from the frame and in particular the protective wall 22, so that the functional integrity of the connection console 1 is also relatively rough Handling of the rammer 50 is guaranteed.
  • the lid 20 in its forward or mainward direction, has a lip 63 which extends obliquely upward away from the adjoining riot wall 20b.
  • a groove 64 is present in the upper edge region of the protective wall 22.
  • the lip 63 and the groove 64 together form another protective device, which counteracts damage to the lid 22. If the protective wall 22, for example, in a fall of the rammer 50 forward pressed in the direction of the lid 22, runs from a certain deformation, the lip 63 on the groove 64, whereby a total relief of the lid 22 is achieved and in this way a irreversible damage to the lid 22 is prevented.
  • the protective wall 22 of the frame 2 is also raised relative to the lip 63 of the lid 20 (edge 24). The protective wall 22 thus protrudes above the lid 20 with the edge 24, whereby a further protection of the lid 20 is obtained.
  • the cover In the region of the rear wall 25, the cover has a projection 27 with which it overlaps the upper edge of the rear wall 25. However, the cover 20 is not seated in this area on the wall, but is spaced from the rear wall 25, so that here also an inlet gap 62 is obtained.
  • connection console 1 is part of an air filter system, cleaned on the sucked ambient air and the in Fig. 1 shown combustion engine 15 is supplied for combustion operation.
  • the connection console 1 By upstanding on the base plate 31 uprising walls 20b a subdivision of the receiving space 10 in an antechamber 61 and an inner space 60 is reached, which are flowed through by the sucked air in succession.
  • the interior space 60 is the area which is surrounded by a part of the cover plate 20a, the uprising walls 20b and a part of the base plate 31 when the cover 20 is inserted into the connection bracket 1.
  • the vestibule 61 is the free space in the receiving space 10, which is formed between the outside of the uprising walls 20 b and the frame 2 within the connection console 1.
  • the antechamber 61 is sealed relative to the interior 60. Specifically, the sealing takes place via a labyrinth seal 29 formed between the end region of the uprising walls 20b directed towards the base plate 31 and the base plate, wherein, for example, in FIG Fig. 11 only the sealing edge of the labyrinth seal 29 located in the base plate 31 is indicated.
  • the labyrinth seal 29 allows a direct sealing of the supporting walls 20b with respect to the base plate 31, so that it is possible to dispense with additional sealing elements.
  • the cleaning of the sucked air is preferably carried out in two stages, wherein an operation of the rammer is readily possible with only one filter stage.
  • initially unfiltered air drawn in from the surroundings of the connection console 1 flows via the entrance gap 62 between the cover 20 and the frame 2 into the receiving space 10 of the connection console 1.
  • Particularly coarse particles settle already in the antechamber 61 on the corresponding region of the base plate 31 and can be discharged from the antechamber via discharge holes 64 located in the base plate.
  • the discharge holes 64 are arranged to the bottom of the vestibule 61 in the base plate 31, which is located in the adjacent to the protective wall 22 region of the base plate 31.
  • the coarse particles automatically slip to the discharge holes 64 during operation, so that a self-cleaning function is obtained.
  • the vestibule 61 can be easily cleaned with water, which also runs by itself to the discharge holes 64.
  • the primary filter 9 projects with its air outlet through a corresponding hole in the supporting wall 20b.
  • the air thus flows after their entry in accordance with arrow a in the antechamber 61 and within the antechamber 61 (according to arrows b) to the primary filter 9.
  • the air flows through the primary filter (arrows c ) and is subjected to coarse filtering. Filtered coarse particles fall from the cyclone in a conventional manner in the vestibule 61 and can be discharged via the specially arranged below the primary filter 9 additional discharge hole 64 'in the base plate 31 from the connection console 1.
  • a secondary filter 7 (specifically, a ring filter) is arranged, to which the air in the interior 60 flows according to arrows d.
  • the air then flows through the secondary filter 7 (arrows e, specifically in the radial direction inwards) and is thereby subjected to further purification, wherein fine particles are filtered out of the air and settle on the base plate 31 in the region of the interior 60.
  • a valve-controlled particle outlet 40 is provided with a valve 41 which opens on the basis of internal pressure changes, via which the foreign particles can leave the air filter housing 18 of the connection console 1 again. Also in the region of the interior 60 thus a self-cleaning function for independent particle discharge is present.
  • the air filter connection 8 After passing through the secondary filter stage 7, the air, which has now been cleaned of particles, is discharged via the interior of the air filter connection 8, which is in communication with the suction line 37, as shown in arrow f from the connection console 1 to the internal combustion engine.
  • corresponding passage openings are provided in the air filter socket 8 designed as an air filter socket.
  • the sucked from the environment of the connection console 1 and filtered in the air filters 7, 9 combustion air thus penetrates the base plate 31 via an air guide passage 35, which via a suction line 37, the filtered air to an air outlet opening 38 leads (see esp. Fig. 6 and 7 ). In the region of this air outlet opening 38 then engages an intake manifold or similar component of the drive unit 16 and in particular of the internal combustion engine 15, which then feeds the supplied filtered air to the combustion operation (not shown).
  • connection console 1 thus has a double air filter system.
  • the two filter stages 7 and 9 are each used to separate particles from the air in order to be able to supply the combustion engine with combustion-air that is as free of particles as possible.
  • the primary filter stage 9 is removably attached to the connection console 1.
  • an unspecified connection device is provided.
  • an operation of the rammer 50 is therefore possible even without a primary filter stage used, with sufficient air filtration still being obtained via the secondary filter 7.
  • the operator can thus decide whether he operates the rammer 50 with or without primary filter stage 9 used.
  • the secondary filter stage 7 is formed replaceable.
  • the lid 20 must be removed from the connection console 1, so that the secondary filter stage 7 is accessible.
  • Another essential detail of the present concrete embodiment of the invention is that the holder of the secondary filter stage 7 is achieved substantially over the clamped in the connection bracket 1 cover 20, which thus also fulfills a dual function in this regard.
  • the ring filter (secondary filter 7) is clamped between the base plate 31 and the lid 20 in the axial direction and fixed in position. The ring filter is to do so with its front-side inner edges on the cover 20 and opposite to the base plate 31, the lid 20 is screwed onto the formed as an air filter base air filter port 8 (for example, according to Fig. 13 ).
  • connection console is thereby provided with additional functions, which again the production process can be streamlined.
  • the main advantage of this special arrangement of the suction line is that the air duct is substantially heat-decoupled from the drive element 16 and in particular the gear housing in the drive element storage, so that the sucked air is not heated in this area.
  • connection console 1 has a rib structure 28 of a plurality of adjacent honeycomb 32.
  • the individual honeycombs 32 are formed by honeycomb walls 30, which form the rib structure 28 as partially common honeycomb walls. The result is a very light, yet stiff component that is elastically optimized with respect to vibration loads.
