Abstract

A method and a device serve to locally impregnate a piece of wood (6) with a gaseous or liquid wood impregnation agent, which is injected under pressure by means of an injection apparatus (70) into a hole (7), which is drilled in the wood and closed with a valve (44) defining a cavity (10). To obtain the greatest possible propagation of the impregnation agent in the wood the air of the cavity (10) is first removed either by flushing the cavity with impregnation agent or directly evacuating the cavity of air. The device comprises an elastomeric valve (44) having at least one internal valve channel (42, 63) which is clamped tightly together along a portion in the longitudinal direction when the valved is pressed into the drilled hole, as well as an injection apparatus having a needle associated with each valve channel to drive into the respective valve channel upon injection and thereby connect the injection apparatus with the hole. The valve channels are closed with pins after the injection, which are provided on a disc that changes its colour after a predetermined period of time of e.g. 3 years to indicate that impregnation should be repeated.
