  • the tank for vaporizable liquids comprises a cavity that is defined by at least one wall, which comprises an orifice, through which a vaporizable liquid is pressable.
  • the pressure generator is arranged in the second compartment such that it directs a pressure of the vaporizable liquid against the orifice to create a flow of the vaporizable liquid from the second compartment through the orifice and out of the tank.
  • the wall with the orifice is arranged at or forms the base of the tank.

  • said wall is a top wall of the tank to ensure that the piston transfers the pressure form the spring to the vaporizable liquid.

  • the gauge is preferably linked to the pressure generator and/or regulator via data technology, wherein preferably the gauge is able to send a regulation signal to the pressure regulator in order to trigger the opening of the valve.
  • the pressure exerted on the vaporizable liquid is automatically controllable with respect to the filling level of the vaporizable liquid.
  • the pressure can be regulated such that e.g. the pressure increases with decreasing filling level so that a constant amount of liquid is flowable through the orifice of the tank, in particular when the tank and the device is used in a horizontal position.
