Abstract (en)
[origin: US6666355B2] A device for dispensing fluids from a sealed off-storage container includes a housing placed on the container that receives a pressure cylinder for insertion in the container. The cylinder has a pressure chamber defined at the upper end by a piston guided in the cylinder and at the lower end by a valve. The valve acts upon the container and is closed when there is an excess pressure and opens when there is a negative pressure in the chamber. The piston has a pump channel linked with the chamber, and the cylinder has openings upstream of the chamber for drawing off residual air present in the container. A passage between an outer wall of the piston and an inner wall of the cylinder upstream of the openings is closed by a sealing washer. Residual air is drawn off via the openings and the passage, whereby the sealing washer loses its sealing effect on the piston.
