       wherein the partition wall is provided with a protruding guide element, 
       wherein the closing element is surrounding the protruding guide element, and wherein the passage opening in the partition wall is allocated in or adjacent the protruding guide element. 
     
     
         2 . Pressure control device according to  claim 1 , characterised in that the closing element and the protruding guide element are moveable connected such that the closing element and the protruding guide element are gas-tight enclosing a pressure chamber. 
     
     
         3 . Pressure control device according to  claim 1 , characterised in that the closing element is hood-shaped. 
     
     
         4 . Pressure control device according to  claim 1 , characterised in that the protruding guide element is surrounded by a slot-shaped channel. 
     
     
         5 . Pressure control device according to  claim 4 , characterised in that the slot-shaped channel is recessed in the partition wall. 
     
     
         6 . Pressure control device according to  claim 4 , characterised in that the at least one passage opening is allocated in the slot-shaped channel. 
     
     
         7 . Pressure control device according to  claim 6 , characterised in that the at least one passage opening is allocated in the bottom of the slot-shaped channel. 
     
     
         8 . Pressure control device according to  claim 1 , characterised in that the inside of the closing element contacting the protruding guide element or the outside of the protruding guide element contacting the closing element is covered with a flexible sealing material layer. 
     
     
         9 . Pressure control device according to  claim 1 , characterised in that the inside of the closing element the protruding guide element contacting or the outside of the protruding guide element contacting the closing element is provided with a annular sealing element. 
     
     
         10 . Pressure control device according to  claim 1 , characterised in that the protruding guide element is cylindrical. 
     
     
         11 . Pressure control device according to  claim 1 , characterised in that the protruding guide element is stationary connected with at least one support that externally seizes on the closing element. 
     
     
         12 . Pressure control device according to  claim 11 , characterised in that at least one external closing element support is provided with an abutment limiting the maximum freedom of movement of the closing element. 
     
     
         13 . Pressurized fluid container provided with a pressure control device according to  claim 1 , wherein the pressure control device is attached in the pressurized container separating a dispersible fluid compartment from a propellant compartment such that the at least one passage opening in the separating wall is the only fluid-permeable connection between the dispersible fluid compartment and the propellant compartment. 
     
     
         14 . Pressurized fluid container according to  claim 13 , characterised in that the propellant compartment is an individual container that is placed in a larger dispersible fluid compartment. 
     
     
         15 . Pressurized fluid container according to  claim 13 , characterised in that the fluid container is a cylindrical spray can. 
     
     
         16 . Pressurized fluid container according to  claim 15 , characterised in that the partition wall is disc-shaped separating a dispersible fluid compartment and a propellant compartment within the cylindrical spray can. 
     
     
         17 . Pressurized fluid container according to  claim 13 , characterised in that the pressure control device is allocated on a distance of a central axis of the pressurized fluid container and a propellant filling valve connecting to the propellant compartment is allocated centrally in the partition wall of the pressurized fluid container.
