|Title:||Device for producing high pressure in a fluid in miniature|
|Abstract:||A miniaturized device for producing high pressure in a fluid imposes stringent requirements on the manufacturing process. The device according to the invention consists of a hollow piston displaceably mounted in a cylinder and a valve member which is guided by the hollow piston and mounted so as to be axially movable relative to the hollow piston. The valve member is arranged at one end of the hollow piston inside or immediately in front of the end of the hollow piston. The device is used in a mechanically operated high pressure atomizer. This consists of a two part housing which comprises a pump housing with nozzle, a blocking mechanism, a spring housing with spring, a non-pressurized storage container for the fluid and a medical counter integrated in the spring housing. The valve operates without any auxiliary force, closes very rapidly and is sealed tight against high pressure. The atomizer is safe and simple to operate and environmentally friendly. The fluid is metered extremely accurately. The atomizer is used, for example, to produce an inhalable aerosol of a liquid medicament without the use of propellant gas, at 320 bar, for example.|

|Filing Date:||Mar 24, 2004|
|Claims:||1. A device for pressurizing fluid, the device having an inlet end and an outlet end, the fluid exiting from the device at the outlet end and moving into a pressure chamber, the device comprising: a hollow piston having a piston axis, said hollow piston providing a path for fluid through the device; a closure member, wherein said hollow piston comprises a widened portion at an inlet end of said hollow piston and a remainder portion, said closure member coupled to said widened portion; a valve member located in the closure member having a valve axis, said valve member configured for axial movement wherein the valve axis remains parallel to the piston axis, said valve member movable between an open position and a closed position; a stop means for limiting axial movement of said valve member; and a sealing surface located in the closure member for sealing an inlet end of said valve member so that said valve member is sealed when in the closed position, wherein fluid flows through the device into the pressure chamber when said valve member is in the open position, and moving said valve member from the open position to the closed position pressurizes fluid in the pressure chamber. |
2. A device according to claim 1, wherein said closure member defines a depression in which said valve member is mounted, said valve member being axially movable in said depression, and wherein said depression has a base that forms said sealing surface.
3. A device according to claim 1, further comprising: a displacement body disposed within said remainder portion of said hollow piston, said displacement body defining a channel for fluid.
4. A device according to claim 2, wherein said valve member defines a channel at an outlet end of said valve member to facilitate flow of fluid through the device when said valve member is in the open position.
