The present disclosure concerns a spring device with a piston and a housing into which the piston can be introduced in a movement direction. A cavity is formed between the piston and the housing, in which cavity a compressible solid body spring is arranged that consists of a solid body that can be compressed by the piston. At least one surface of the piston that faces the solid body spring is conical or concave. The disclosure furthermore concerns a securing device comprising such a spring device and the use thereof, in particular for a container closing plug.

Spring device and securing device for securing a machine element, and use thereof

A device for high-pressure treatment of goods in a sealable high-pressure chamber may include a holding frame that holds the high-pressure chamber during pressurization, a closure having a sealing plug for sealing the high-pressure chamber, a hydraulic drive for moving the closure relative to the pressure chamber, and a support device that is movable between an end face of the high-pressure chamber and the holding frame and transmits force between the closure and the holding frame during pressurization. Axial forces acting on the sealing plug from the pressure may be absorbed by a force-transmission device configured as a semicircular disk. The semicircular disk may have an end face that faces the high-pressure chamber and a holder for a hydraulic cylinder. The semicircular disk may form a part of the outer shell of the hydraulic cylinder bearing the hydraulic pressure.

Container sealing device for high-pressure chamber

The present disclosure relates to a high-pressure valve for use in an installation for the high-pressure treatment of products in a high-pressure chamber, wherein the products, acted on by a high-pressure medium, are treated at a pressure of up to 10 000 bar.
