Abstract (en)

[origin: WO0230577A1] The invention relates to a device for dispensing fluids from a sealed off storage container. Said dispensing device comprises a housing (2) that can be placed on the storage container (1) and that receives a pressure cylinder (5) that can be inserted in the storage container. Said pressure cylinder is provided with a pressure chamber (6) that is defined at the upper end by a piston (7) guided in the pressure cylinder and at the lower end by a valve (8). Said valve acts upon the storage container and is closed when there is an excess pressure and opened when there is a negative pressure in the pressure chamber. The piston (7) has a pump channel (14), linked with the pressure chamber (6), and the pressure cylinder (5) has openings (12) upstream of the pressure chamber for drawing off the residual air present in the storage container. A passage (10) is configured between the outer wall of the piston and the inner wall of the pressure cylinder upstream of the openings (12) and is closed off by a sealing washer (19). The residual air is drawn off via the openings (12) and the passage (10), whereby the sealing washer (19) loses its sealing effect on the piston (7). Once the residual air is drawn off, the passage is again tightly closed off by the disk (20).
