Abstract: A press plant includes a press of pressure cell type, into which a tray device, which defines a space intended to receive a workpiece and, optionally, a forming tool, is insertable. The tray device comprises a tray plate and a tray frame. The tray frame is adapted to independently withstand, at least in certain portions, loads applied during the pressing operation. The tray device is divisible into at least an upper part and a lower part. The invention also relates to a method and use of a tray device in a press plant.

Abstract: A high-pressure press includes a pressure vessel surrounded by a force-absorbing press frame. The high-pressure press also includes a detection structure for detecting changes in length of at least one column comprised in the press frame, the changes in length depending on the pressure inside the pressure vessel. The detection structure includes a limit switch, which is adapted to detect if the change in length of the column has reached a threshold value and, in that case, interrupt a pressing operation in progress and reduce the pressure inside the pressure vessel.

Abstract: The invention relates to a press of pressure cell type, which comprises a press chamber in which a diaphragm device is arranged. The diaphragm device includes a diaphragm which together with a press plate forms a pressure cell and is adapted to exert a forming pressure on a workpiece in the press chamber. The edge area of the diaphragm is placed in an annular diaphragm support. The press of pressure cell type also comprises actuating means which are adapted to actively exert a force on the diaphragm support in the direction of the press plate, the diaphragm support pressing the edge area of the diaphragm against the press plate so that an initial seal is provided between the diaphragm at its edge area and the press plate, which seal is built up when supplying pressure medium to the pressure cell by expansion of the diaphragm. The invention also relates to a diaphragm device, a method for applying a pressing power and a method for exchanging a diaphragm in a press of pressure cell type.

Abstract: A high-pressure piston compressor (1) for compressing gas, comprising a vessel (4) having a vessel chamber (8, 23) wherein a piston (3) is guided reciprocally, for compressing a gas in the vessel chamber during operation of the piston compressor, an inlet valve housing (17, 29) comprising an inlet valve (18, 30), and an outlet valve housing (15, 31) comprising an outlet valve (16, 32), wherein the inlet valve housing and the outlet valve housing are mounted within a portion of the vessel chamber wall (14, 28), and wherein the portion of the vessel chamber wall encloses the inlet valve housing and the outlet valve housing, such that the portion of the vessel chamber wall generates an isostatic counter-pressure on the inlet valve housing and the outlet valve housing in response to the pressure on the inlet valve housing and the outlet valve housing from the gas in the vessel chamber during operation of the piston compressor.
