Abstract: The invention relates to a flanged connection for jacketed high-pressure pipes rated for 300 to 10,000 bar, in which the jacket pipe end of at least one of the two jacket-side high-pressure pipe flanged connections is designed as jointed flange, said flange being fixed on the outer side of the high-pressure pipe by means of a jointed connection, said connection being suited to absorb the longitudinal forces in axial direction of the high-pressure pipe and the jointed flange being provided with the bores necessary for the bolts.

Abstract: A high-pressure generating apparatus including a high-pressure chamber, a low-pressure chamber located beneath the high-pressure chamber and having a diameter substantially larger than the diameter of the high-pressure chamber, a tandem piston having first and second portions displaceable in the high-pressure and low-pressure chambers, respectively, for building-up pressure therein, and a yoke embracing the high-pressure and low-pressure chambers for applying a pressure force to the high-pressure chamber cover and the low-pressure chamber bottom upon built-up of pressure in the high pressure and low-pressure chambers.
