Abstract

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.
