摘要： A high pressure press for treatment of substances such as food includes a floating piston in a pressure chamber, with seals. The floating piston has drainage system for collecting any pressure fluid that leaks past a seal of the floating piston. The drainage system includes a pressure reducer arranged inside the floating piston. The drainage system also includes an elastometic pad which is so arranged as to supply an underpressure to a space where pressure fluid leaking past a seal may collect. Collected pressure fluid is returned to the pressure chamber later in the cycle.

摘要： A method for treatment of one or more wood elements by pressurization comprises the steps embedding the wood elements into a pressure medium, of increasing the pressure in the pressure medium, whereby the wood element is compressed by transmitting the pressure via the pressure medium to the wood elements, and of reducing the pressure in the pressure medium, whereby the wood element is relieved. During the treatment, liquid present in the wood elements is driven out therefrom. The pressure medium comprises a plurality of solid bodies with intermediate spaces. The solid bodies transmit the pressure to the wood elements such that a pressure difference arises between the wood elements and said spaces, which pressure difference drives out the liquid. During the relief phase, the wood elements substantially resume their original shape. The method can also be used for introducing impregnating liquid into the wood elements after the liquid expulsion.

摘要： A press of pressure cell type comprises a press stand with two opposing force-absorbing elements between which a space is formed. In this space there is located a plate with a recess in which an elastic diaphragm is arranged. The diaphragm forms, together with the plate, a pressure cell. Elongated side supports for the diaphragm are provided at the sides of the said space. A tray insertable into the space forms, together with the plate and the diaphragm, a closed press space. The pressure cell is connected to a pressure medium source. Each side support is formed with an elongated recess, in which there is arranged an expansible membr of elastic material. Each expansible member forms a side support for a press tool located in the tray.
