Abstract
A device for pressure treatment of wood elements comprises a pressure chamber (1) for accommodating the wood elements (5a, 5b, 5c) which are to be treated. The pressure chamber also accommodates a pressure medium which surrounds the wood elements on more than one side and, at least before the pressurization, a secondary medium in the form of a fluid. When the pressure medium is pressurized, the wood elements are subjected to a multilateral pressure, whereby they are permanently compressed. Further, the pressure chamber is provided with means (11a, 11b) for controlling the quantity of secondary medium which penetrates into the wood during the treatment.
These means may consist of evacuating valves (11a) or of casings (11b) which surround the wood elements and which are impenetrable to the secondary medium.
These means may consist of evacuating valves (11a) or of casings (11b) which surround the wood elements and which are impenetrable to the secondary medium.
