Definitions

  • the invention relates to a suction device for suction and collection of fluids or fluid mixtures, and a plug for sucking and discharging fluids or fluid mixtures, which is particularly intended for use with a suction device.
  • a suction device sketched in FIG. 3 in which a fluid mixture F with liquid and gaseous content is conveyed into a container.
  • the container is located in a gastight chamber. Gas present in the chamber, e.g. Air is sucked by means of a connection via a line to a pump, so that a negative pressure is created in the chamber. Due to the negative pressure, the pressurized fluid mixture F is conveyed through a conduit and a second port into the container.
  • Gas present in the chamber e.g. Air is sucked by means of a connection via a line to a pump, so that a negative pressure is created in the chamber. Due to the negative pressure, the pressurized fluid mixture F is conveyed through a conduit and a second port into the container.

This ensures that the pressure in the tank is always lower than the ambient pressure remains, and the liquid portion of the fluid mixture is still collected in the container, while the gaseous portion of the fluid mixture is discharged through the conduit on to the pump.
  • the second and the third connection and the container are made in one piece with a lid. Due to this construction, both the lid and the second and third ports connected thereto must be replaced with the container by removing the entire assembly by a new assembly after the container is completely filled with liquid. On the one hand, this is disadvantageous for reasons of cost, but on the other hand, even a single use of the components, which are preferably made of plastic, is questionable from an ecological point of view.
