Definitions

  • the present invention relates to a compressor head and especially a compressor head with elastic beak valves
  • compressors and pumps are known to be one liquid or gaseous medium in a compression room compress.
  • piston compressors or Diaphragm pumps make up the volume of a compression chamber an oscillating movement of the compression space final piston varies periodically.
  • the inflow of the medium to be compressed in the compression space or that Outflow of the compressed medium from the compression space is controlled via appropriate valves, which are usually are disc-like or flap-shaped.
  • a compressor arrangement known which is an air inlet chamber, an air outlet chamber and has a compression chamber.
  • the air intake chamber and the air outlet chamber are separated from each other and each via a valve with the compression chamber, the Volume through the periodic movement of a piston is enlarged or reduced, connected.
  • the used Valves that have an inflow or outflow of air, respectively Enable or prevent in the desired way are here flap-shaped.
  • the opening between Air intake chamber and compression chamber is from that disc-shaped valve element, which with the help of a screw is fixed on one side during a suction process, i.e. if the compressor room volume increases, by a one-sided Lifting of the valve element released. simultaneously another valve element closes the opening between Compression chamber and air outlet chamber.
  • the opening is between Air inlet chamber and compression chamber closed and at the same time, a valve element between the opening Air outlet chamber and compression chamber free, so that compressed medium from the compression chamber into the Air outlet chamber flows out.
  • the openings between corresponding inlet, outlet and Compressor rooms can also have elastic valve elements have, which are designed such that the disc-shaped valve elements not only attached on one side are, but in several places, for example symmetrical around the opening.
  • An opening or closing then takes place by lifting the entire elastic valve element perpendicular to the surface of the opening. Penetrates, for example a gaseous or liquid medium from below into one with such a valve element closed opening, so the entire valve element is raised due to the flow and the medium escapes through the opening. That flows gaseous or liquid medium from the opposite Side in the direction that closes the opening Valve element, so the valve element due to the flow pressed against the opening and closes it.
  • the known valve elements are made of plastic, for example, Rubber, silicone or other flexible plastic manufactured.
