Definitions

  • the noise damping body is preferably in the pressure port guided pipe section, being used to hold the sound absorbing body expediently a special one in the pressure port Device can be provided.
  • a special one Feature of the invention this is a in a circumferential groove of the pressure connector insertable, elastic sealing ring, by its frictional force as a noise damping body in the Discharge pipe inserted tube is kept.
  • On this pipe can be provided a paragraph or the like, which in cooperation unintentionally with the holding means or the sealing ring prevented from sinking far into the pressure chamber.
  • Another feature of the invention is in the pressure chamber Support stop provided on which the lower end of the as Sound absorbing body supports the pipe.
  • Fig.2 you can see the working space 1 of the pump, in which the impeller 2 rotates and through the control disc 3 of the pressure chamber 4 is separated.
  • the control disc 3 contains one or several pressure openings 5 through which the compressed medium with part of the operating fluid from the work area 1 passes into the pressure chamber 4.
  • To the pressure room 4 joins the pressure nozzle 6 upwards through which the gas and the excess operating fluid are removed.
  • the pressure port is arranged vertically. This is advantageous but not absolutely necessary.
  • a tubular one can be arranged in the pressure connection 6
  • Noise damping body 7 are used, the diameter is a little less than that of the discharge port. If it is desired that its inside diameter be about the nominal diameter corresponds to the connecting line, the discharge nozzle with a correspondingly larger diameter. Usually this is not considered necessary.
  • the invention allows a series pump in the case of high Retrofitting requirements with the noise reduction body equip without any Changes made to the assembled pump as such should be.
  • the tubular noise attenuator has the simplest Case circular cross section. However, it can be a different one Have cross-section. This is especially true for his lower, end immersed in the pressure chamber. He also needs not to be tubular in its entire length. Also needs the tube shape is not closed on the entire circumference be. However, this is useful in that section, in which of the noise damping body within the pressure port lies so that it is kept evenly on all sides can.
  • the noise attenuation body ends below in a direction perpendicular to its longitudinal direction Face. Since it is in terms of noise reduction function on the wall formation in relation to the rest Area of the pressure chamber and in particular on the position of the lower wall edges arrives at the silencer, the lower one However, the end edge of the silencer body also has one have a different shape. For example, it can be provided that he continues on his side facing the pressure openings 5 reaches down than on its opposite side.
  • the embodiment IV of European patent application 94114730 corresponds, the noise damping body is double-walled, with the two walls tightly connected at the top are in between one down towards the pressure chamber to form an open buffer space.
