Definitions

  • the invention relates to a compressor unit in which a radial piston compressor and its drive motor are arranged in a unit housing together on a fixed axis which is hollow at least in the region of one end and is suspended on the unit housing.
  • Such a compressor unit is known from DE-AS 27 10 734.
  • the fixed axle is rigidly suspended from the unit housing.
  • vibrations and sound waves are transmitted to the unit housing without damping.
  • a compressor unit consisting of an electric motor and a piston compressor is known, in which the motor and the compressor are arranged on a fixed, hollow axis.
  • the axle is movably supported at both ends by springs on the unit housing.
  • the invention has for its object to design a compressor unit of the type described in such a way that the transmission of vibrations and structure-borne noise to the outside is largely prevented by a movable suspension of the fixed axis, the design of the movable suspension being to be space-saving.
  • the object is achieved according to the invention in that the axle by means of a rod-shaped, elastic support member protruding into its cavity and connected at one end to the axle with the axle and attached at its other end to the unit housing is hanged.
  • the elastic support member is dimensioned so that it can transmit the reaction acceleration moments occurring when starting and stopping the compressor unit and the weight of the unit and, moreover, allows the compressor unit to vibrate freely in the horizontal direction.
  • the pressure line of the radial piston compressor can advantageously be provided as a supporting element in a compressor unit in which the axis is hollow at the end on the compressor side. This pressure line is then dimensioned in its length and its cross-section so that it has the elasticity necessary for free swinging. In this way, a separate support member is saved.
  • the compressor unit consists of a radial piston compressor 1 and a drive motor 2.
  • the radial piston compressor 1 and the drive motor 2 are arranged on a common fixed axis 3.
  • the fixed axis 3 is hollow at the end 4 on the compressor side.
  • the pressure line 6 leading to the outside from the radial piston compressor is arranged in the cavity 5 of the fixed axis 3.
  • the pressure line 6 in the cavity 5 is connected to the fixed axis 3 at one end. With its other end 8, the pressure line 6 is attached to a distributor head 10 placed on the unit housing 9.
  • the attachment to the distributor head 10 is carried out by means of a press cone .11.
  • the pressure line 6 is connected to the pressure slot of the radial piston compressor 1 via a channel 12 formed in the fixed axis 3.
  • a cap 13, which forms a pressure chamber 14, is placed on the unit housing 9 above the distributor head 10.
  • the other end of the pressure pipe 6 opens into this pressure chamber 8.
  • the compressed gas can be discharged via a pressure connection 15 provided on the cap 13.
  • a suction nozzle 16 is also formed, which is guided through the wall of the cap 13 to the outside.
  • the distributor head 10 also has, on the side facing the unit housing 9, a suction opening 18 surrounded by an annular flange 17.
  • the fixed axis ends at this suction opening 18. Seals 20 are inserted between the ring flange 17 and the end 19 of the fixed axis 3 projecting into this ring flange hi h .
  • the pressure tube 6 is dimensioned in its length and in its cross section so that it allows horizontal vibrations of the compressor unit due to its elasticity. As a result of the elasticity of the pressure tube 6, these vibrations can only be transmitted to the unit housing 9 to a small extent.
  • a separate rod-shaped support member must be provided in its place.
  • Such a support member can then be tubular, i.e. be hollow or fully formed.
