Abstract
The invention relates to a locking-tensioning mechanism for a miniaturised high-pressure generator, the construction of said mechanism being configured only for the volume of liquid that is to be delivered. The volume that is to be delivered by said high-pressure generator can be retroactively modified by adjusting the stop of the elastic part. The basic components of the locking-tensioning mechanism and the high-pressure generator remain unchanged. At least one additional component is provided as a spacer in the form of intermediate rings, stepped pulleys, adjusting screws or adjusting nuts. A
continuous helical-sliding gear or a helical-sliding gear that can be adjusted in steps can also be used to adjust a stop of the elastic part. The volume to be delivered can be modified either discontinuously or continuously during the assembly of the locking-tensioning mechanism, or prior to the use of the high-pressure generator, or during the use of said high-pressure generator. The locking-tensioning mechanism for a miniaturised high-pressure generator with a reproducibly adjustable volume, lying in the microlitre range, of liquid to be delivered can be used, for example, in a high-pressure atomiser for producing an aerosol that can be inhaled, or in a needle-free injector for injecting a volume of liquid into animal or vegetable tissue.
continuous helical-sliding gear or a helical-sliding gear that can be adjusted in steps can also be used to adjust a stop of the elastic part. The volume to be delivered can be modified either discontinuously or continuously during the assembly of the locking-tensioning mechanism, or prior to the use of the high-pressure generator, or during the use of said high-pressure generator. The locking-tensioning mechanism for a miniaturised high-pressure generator with a reproducibly adjustable volume, lying in the microlitre range, of liquid to be delivered can be used, for example, in a high-pressure atomiser for producing an aerosol that can be inhaled, or in a needle-free injector for injecting a volume of liquid into animal or vegetable tissue.
