Definitions

  • the present invention relates to a piston compressor for gaseous media, especially one with an electric motor driven air piston compressor according to the preamble of Claim 1.
  • a pump of this type is from DE 33 33 329 known. Although the crankcase is open, it seals the pendulum piston used in this device in the cylinder completely. Inlet and outlet valves are located at the top. A different stroke is made by varying the crank arm achieved and the setting of the harmful space happens by alternately inserting spacers. Such Pump is unsuitable for the present purposes.
  • DE 23 11 048 describes a piston compressor as a small one Unit known that is used as a structural unit in motor vehicles is made available to compressed air for various purposes to provide, and largely such compressed air that not necessarily - as with air brakes - via one Compressed air reservoir is directed, but with the at the same time generation work, for example any Units such as windshield wipers or the like are driven or is introduced into an air suspension system.
  • air pressure accumulators can also be filled.
  • compressors are provided with pistons which the piston rod is fixed, that is connected without a joint, as this from the prior art (DE 23 11 048 or DE 36 16 968 A1).
  • the piston bends in the cylinder when and downward movement back and forth and with this type of construction it is not easy to specify top dead center constructively that all products are evenly distributed in series production Desired compression or harmful space.
  • the outlet element with an internal outlet valve centrically and thermally decoupled so that it is in any Position with the fixation of the screw connection between Cylinder and crankcase can be clamped.
  • the piston compressor shown in FIGS. 1 and 2 has a compressor housing 62 and a laterally connected housing 12 for an electric motor that drives the piston compressor serves.
  • the compressor housing 62 is through an electric motor opposite cover 64 closed.
  • the electric motor has a drive shaft 42 through which in the housing wall 62 arranged ball bearing 40 is mounted.
  • the shaft 42 closes in an eccentric 46.
  • a bearing 54 of a connecting rod 56 Located on the eccentric 46 a bearing 54 of a connecting rod 56.
  • the connecting rod 56 supports the bearing 54 at its lower end, whereby the bearing 54 circular by the rotation of the drive shaft 42 to be led.
  • the connecting rod 56 carries one at its other end hereby firmly connected piston 58, which in a cylinder 60 is arranged for reciprocation. In the drawn Position, the piston 58 is at its top dead center. The bottom dead center is indicated by dashed lines.
  • the cylinder 60 is threaded 66 at its lower end provided, by means of which it is screwed into a Opening 68 of the compressor housing 62 is screwed.
  • the opening 68 of the compressor housing 62 is formed so that the connecting rod 56 can move freely here, even with the lateral swiveling caused by the design of the fixed Connection between connecting rod 56 and piston 58 are conditional.
  • the Thread 66 of the cylinder 60 has a narrow pitch, so that the axial cylinder height can be set precisely.
  • the effective axial cylinder height With which the top dead center of the effective in the cylinder 60 Piston 58 can be adjusted.
  • the dashed below indicated lowest position of the piston 58 Area is not effective.
  • the effective axial cylinder height can by screwing the cylinder 60 into the opening 68 of the Compressor housing 62 can be changed.
  • a change in effective axial cylinder height also leads directly to a Change the so-called compression space or harmful Space V, which is due to the top dead center position of the piston 58th is defined.
  • This compression space V should be dimensioned in this way be that it corresponds to the minimum dead space volume, that the system has.
  • the optimal setting of the optimal Compression chamber is done manually during the test run of the piston compressor, so the change in operating behavior can be assessed immediately.
  • valve head 90 there is a space V above spring loaded exhaust valve in valve head 90.
  • This valve consists of a thin metal disc 92, which by a Spring 94 is normally pressed against a sealing ring 96 (see right part of the illustration in Fig. 2 above). At high Pressure opens the valve (left part of the illustration in Fig. 2 above) and there is a path 28 within an outlet head 26 to Outlet connector 20 free.
  • This outlet head 26 has two special features. To the one is freely rotatable in the valve head with loose screws 63 and thermally decoupled.
  • the thermal decoupling is made by two circular lines Support rings and an air gap 25 between the valve head 90 and the outlet head 26 achieved. This heats up the from Nozzle 20 escaping air in the last part of the compressor not in addition and the efficiency improves.
  • the piston compressor according to the invention enables manual Setting the compression space so that it can be used for different Applications, for example as a pump, vacuum pump, Compressed air source for passenger cars, air conditioning systems and the like It is thermally decoupled and provides maximum performance with limited Power consumption designed.
  • the piston compressor according to the invention is therefore particularly suitable for the exchange of electrically operated devices of the car against pneumatically operated units or especially for use in air suspension vehicles too their level or inclination control.
