ABSTRACT:
A press for treatment of material includes a high pressure chamber formed of a vertical high pressure cylinder having end closures projecting into the cylinder and a press stand with a clear opening which is somewhat greater than the length of the high pressure chamber when the end closures are fully inserted. The high pressure cylinder is mounted on a carrying device which can move it into the clear opening of the press stand with gaps between the press stand and the end closures. One of the end closures is constituted by a piston slidable in the high pressure chamber. This piston has an annular portion which is slidable in an annular space formed at the end of the high pressure cylinder. Fluid under pressure can be supplied to the space on the side of the annular projection facing away from the high pressure cylinder to move the piston into the high pressure chamber and holding it there during movement of the high pressure chamber into the press stand, whereafter such pressure fluid can be released.
