Definitions

the invention relates to a compressor with one or several cylinders in a horizontal arrangement and with one Crankshaft in a crankcase.
the object of the present invention is a To create a compressor as compact as possible.
crankshaft is directed vertically is that below the at least one cylinder with a the crankshaft coupled drive unit arranged is that one with the power pack or the Crankshaft coupled fan is provided, and that the fan creates an airflow that goes up on Drive unit and at least one cylinder leads along.
the drive unit preferably an electric motor, arranged below the cylinder. This way a significantly reduced space requirement. Can too the ventilation and cooling of both units by one common air flow.
the vertical arrangement according to the invention - cylinders and Drive unit one above the other - preferably has two Cylinder in boxer arrangement. But are also possible Versions with only one cylinder or with several Cylinders in a different arrangement, such as a star or V arrangement. In all cases, the cylinders are transverse to vertical crankshaft or drive shaft provided.
the drive unit is advantageously in the sense of a Direct drive coupled to the crankshaft. Is possible but also an indirect drive via a gear.
a fan for generating a Airflow arranged below the cylinder, and especially below the Drive unit.
the fan is preferably as Radial fan executed, the axially in one Area of the fan flowing away from the cylinders Air flows out in the radial direction and on the side Drive unit and / or up on the cylinders. There will be an upward flow of air for the Cooling air and intake air are generated.
Drive unit and Cylinders are equipped with cooling fins. The upward flowing air sweeps past and causes effective cooling. Because of the compact design modern electric motors project the cylinders laterally and lie exactly in the cooling air flow.
a (First) suction filter provided, preferably one Filter mat. This is close to an inlet opening inlet housing upstream of the fan.
a (second) air filter is assigned to the cylinders, in particular an air filter for several cylinders together.
the air filter is above the cylinders provided, especially in the middle. Air intake openings of the Air filters are in the range of the aforementioned upward flowing air.
the air filter has a suction regulator, so that short-term funding for all connected Cylinder interrupted and thus the operation of the Compressor adapted to a lower compressed air requirement can be.
a suitable intake air duct (the one to be compressed Air) can supply warm air to the air filter be avoided.
the intake air duct is a pipe with corresponding cross section.
the suction opening has one sufficient distance from heat-radiating surfaces, especially cooling fins. The actual distance is of the specific temperature and flow conditions dependent.
the upward airflow is advantageously through air guiding elements on the cylinders and on the crankcase and / or guided along the drive unit. This can faster heat dissipation can be achieved.
the air guiding devices are of the Cylinders uncoupled.
the compressor unit - cylinder, crankcase and Drive unit - is stored in a housing.
the Air control elements are assigned to the housing, while the Compressor unit is mounted so that it can vibrate in the housing.
the air to be compressed is transferred to the cylinders Upper sides fed and on the lower sides as compressed air taken.
Corresponding compressed air lines run in one level below the cylinders and lie in the upward airflow.
the cylinders are through a common compressed air line connected with each other. Sits from one of the cylinders this compressed air line continues and is in the same horizontal plane around the crankcase, in particular by 180 ° or more.
the circumferential shows Compressed air line a sufficient distance from Crankcase on, so that the heat of the Pipes through the coolest possible rising air is dissipated.
the air filter located near the cylinders has advantageously insulated walls, especially an insulating floor slab. A warming of the air entering through the air filter housing is thereby avoided.
the drive unit and cylinder form one vibration engineering unit. Is correspondingly low the resonance frequency. This will be through further measures additionally reduced. So unity is relative stored low. Support arms are provided for this purpose free support arm ends on the housing side at bearing points in one Height below a transition between the cylinders and the drive unit are stored. On the part of unity grab the support arms between the crankcase and the drive unit. The free arm ends rest Damping elements. These are at the level of the focus the oscillatable unit on the corresponding support beam or struts arranged on the housing.
the unit is star-shaped in the housing due to the support arms stored.
the crankcase is at the center of the Bearing points.
Additional weights are assigned to the cylinders. advantageously - based on the rotation of the Crankshaft - radially outside the cylinders. With the help of Additional weights can be around the mass moment of inertia Center of gravity of the unit increased and thus in particular the Generation of torsional vibrations can be counteracted.
a piston compressor 10 with two cylinders 11, 12 in Boxer arrangement is together with an electric Drive motor 13 encapsulated in a housing 14, see FIGS. 2 and 3.
the motor 13 is below one Crankcase 15 connected to this.
the one not shown Drive shaft and the crankshaft, also not shown of the compressor are directly coupled and therefore vertical directed.
the crankcase 15 is also called Cylinder console designates and houses an oil-free one Working piston arrangement with two pistons (also Not shown).
the drive motor 13 is suspended. Use this in the area of the transition between engine 13 and Crankcase 15 radially (star-shaped) support arms 16 on. Free ends 17 of the support arms rest Damping elements 18. These can be a rubber pad or have the same and are with parts of the housing firmly connected. In this way the unity is over Cylinders 11, 12 and engine 13 relative to housing 14 capable of vibrating. The free ends 17 lie approximately half the height of the drive motor 13. This is achieved a relatively low resonance frequency.
the resonance frequency is also reduced by Additional weights 19.
One weight is one cylinder assigned and sits in front of its face. Show by this the additional weights 19 the greatest possible distance from Focus on and increase the moment of inertia by the common focus.
the connection between the Cylinders 11, 12 and the additional weights 19 can for example by elongated cylinder studs or bolts arranged parallel thereto may be provided.
a radial fan 20 closes at the bottom of the drive motor 13 on, which rotates with the drive shaft, not shown.
the Air supply for the radial fan 20 takes place axially from below via a nozzle 21. This is assigned to the housing 14, during the radial fan 20 with the drive motor 13 connected is.
the nozzle 21 and radial fan are corresponding 20 separated from each other in terms of vibration.
the air emerging radially from the radial fan 20 becomes by an air guiding device arranged in the housing, in particular lower air baffles 22 and up cools the drive motor 13, the cylinders 11, 12, the Crankcase 15 and other parts subject to heat.
the heated air eventually occurs in an upper area out of the housing 14, see air outlet 23 in FIG. 2 and 3.
FIG. 1 shows a exploded view of the air filter 24.
the intake pipe 28 extends over more than 2/3 of the height of the crankcase 15. As a result The air heated on the crankcase does not get into the Air filter 24.
the bottom plate 25 and possibly other parts of the Air filter 24 are heat insulating, so that too no excessive heating of the via a heat conduction Intake air can take place.
the air filter 24 has one for both cylinders 11, 12 common controller 29, see Fig. 5.
Fig. 1st is only a recess in the frame 26 for the controller 29 recognizable.
controller 29 is an extreme short-term regulation of compressed air delivery possible. The more or less strong release of the Intake air on the way to the cylinders 11, 12.
Die Intake air is supplied via appropriate intake lines 31, 32 supplied from the air filter 24 to the two cylinders 11, 12, see Fig. 2.
the air filter 24 has for this purpose corresponding connection piece 33.
the compressed air generated is in a special way in the housing 14 out. Both cylinders are through one below the same compressed air line running in a horizontal plane 34 connected to each other, see Fig. 1.
Die Compressed air line 34 begins at cylinder 11 and settles beyond cylinder 12 (more precisely below the same) and is once around the crankcase guided around, always in the same horizontal plane.
Fig. 1 is the part continued from the cylinder 12 of the Compressed air line covered and only parallel to the Compressed air line 34 extending part (compressed air line 35) visible.
Whose end piece 36 is approximately below the Cylinder 12. The compressed air escapes from the housing is not shown.
the housing 14 with cover plate 37, large side walls 38, 39 and narrow side walls 40, 41 encapsulates the compressor 10 against noise emissions and dust.
An open one The bottom is covered by a large filter mat 42 and thus serves as an air inlet, the filter mat 42 is in lateral guide rails held. That way a dust accumulation inside the housing avoided.
Filter mat 42 can also use other air filters come.
this has near the cover plate 37 an opening 43 which extends over the entire width of the Side wall 40 extends.
air guiding elements 47, 48 in particular air baffles arranged. This extend across the width of the large side walls 38, 39 and are directed obliquely upwards, near the cylinders 11, 12 and above the compressed air lines 34, 35. As a result the upward flowing cooling air becomes close to the Crankcase 15 passed and the flow rate increased in this area. This causes an efficient one Cooling.
the intake pipe 28 extends straight into the narrowest area between air guide 47 and Crankcase 15.
the nozzle 21 is inserted into an intermediate floor 49. This is parallel to the bottom and thus forms one Suction chamber 50 for the nozzle 21. Preferably is on the Intermediate floor insulation material applied. This is shown in Fig. 2 hatched and otherwise not closer shown.
the housing 14 is constructed as a frame structure, such as 4 can be seen. Outer upright struts 51 stand on cross struts 52 of a subframe 53. Above the Subframe 53 and at a distance from this is the Intermediate floor 49 retracted. On a narrow side wall 41 is a control cabinet 54 above the intermediate floor 59 arranged.
a middle frame 55 with corresponding cross struts 56 with the upright Struts 51 connected.
the cross struts 56 are the Damping elements 18 held. So that's it Compressor unit on the middle frame 55 oscillates stored.
the compressor 10 described can be used in many different ways can be varied. So other cylinder arrangements be provided, about 2x2 cylinders, each in a boxer arrangement, with an offset of 90 ° to each other, or one multi-stage arrangement in which the one cylinder escaping compressed air is sucked in by the next cylinder and is further compressed. Can also be oil-lubricated Piston-cylinder arrangements can be installed.
the Crankcase 15 can then be fully encapsulated. In the present embodiment has the crankcase each on the free sides (at the top) between the Cylinders V-shaped passages 57, in Fig. 1 is the concealed rear passage. This will get cooling air into the Crankcase into it. This is supported by the Design and arrangement of the air guiding elements 47.
