Liquid-filled pressure cylinder for the static high-pressure equipment

摘要

Known pressure cylinder for the static high-pressure equipment have an external high-pressure pump which is connected, via connecting elements are connected with the impression cylinder. However, arrangements of this type are relatively expensive and costly, in addition, they can be adjusted only with difficulty. The fluid-filled pressure cylinder according to the invention therefore has an integrated pressure generation in the form of a cover - piston - combination (3), which comprises a cover (9) and a connected thereto in one piece, in the pressure cylinder (1) by means of a sealing system (11) in a pressure-tight manner and piston guided in a fitting (10) is built up. By means of a plurality of screws (12) on the circumference of the cover (9), the cover - piston - combination (3) with the impression cylinder (1) under variable pressure of the piston (10) directly on the liquid filling can be screwed in the pressure cylinder (1). By this simple and cost-effective arrangement can be finely dispensing by means of a controllable adjustment of the piston (10) in the liquid (2) static high pressures to in a range of far above 1 · 10⁸ Pa be applied permanently. The printing cylinder can be used according to the invention, in particular in measurement technology, and, for example, for the examination of pressure adapted organisms from the deep sea.
