Abstract

A locking tensioning mechanism for a miniaturised high pressure generator is disclosed, which mechanism will allow delivery of a set volume of a liquid, and the volume to be delivered by a high pressure generator can be altered subsequently by adjusting one of the stops of the spring component, which locking tensioning mechanism may be used in a high pressure generator for producing an inhalable aerosol or in a needleless injector for injecting a volume of a liquid into animal or plant tissue.
