ス不含にすることができる。BACKGROUND OF THE INVENTION Impregnating containers of this type are used for impregnating liquid impregnating agents, such as synthetic resins or oils, into the object to be impregnated. One typical example is the impregnation of the coil with synthetic resin. The advantage of vacuum impregnation is that before the impregnating agent enters the pores and hollow chambers of the object to be impregnated, air and other gases are extracted from these hollow chambers by a pressure drop (vacuum), so that the impregnating agent flows into the hollow chambers. It is possible to be completely charged. Furthermore, the impregnating agent can then be made gas-free to such an extent that it can absorb into itself any residual gas that still remains in the hollow space.

造費で達成される、専ら供給装置を、含浸剤が容器の周
囲全体にわたって分配されるように構成するだけでよい
。Function: In an evacuated impregnating vessel constructed in this way, the impregnating agent flows over the vessel wall in the form of a thin film and is degassed. The spread of the impregnating agent in a thin and therefore large-area layer is extremely favorable for the release of gas, so that at the bottom of the container the well-degassed impregnating agent collects and the impregnated object contained in the container Cover things. This advantage is achieved with significantly lower construction costs; it is only necessary to construct the feeding device in such a way that the impregnating agent is distributed over the entire circumference of the container.
供給装置は有利には容器内に配置された環状導管を有す
る（特許請求の範囲第２項）。この構成は特に有利であ
る、それというのも容器壁の漏れのない貫流だけが必要
であるにすぎないからである。The supply device preferably has a ring conduit arranged in the container (claim 2). This configuration is particularly advantageous since only a leak-free flow through the container wall is required.

れば、容器室内に遮蔽壁が配置されている。この遮蔽壁
は同様に、含浸剤をガス抜きのために面状に展開させる
（特許請求の範囲第４項）ために、有利に利用される。According to an advantageous embodiment of the invention, a shielding wall is arranged in the container chamber. This shielding wall is likewise advantageously used to spread out the impregnating agent in a planar manner for degassing (claim 4).
遮蔽壁によって、有効室が場合によってなおガス抜きさ

ス抜き室を上向きに容器室に対して開口させるのが有利
である（特許請求の範囲第４項）。この構成は含浸剤か
ら放出するガスを吸込むために特に好適である。By means of the shielding wall, the useful space is shielded from any impregnating agent that has not yet been degassed, so that the impregnated material is covered from below by the impregnating agent flow in the conventional manner. In the case of a structure with a shielding wall, it is advantageous for the degassing chamber between the shielding wall and the container chamber to open upwards into the container chamber (claim 4). This configuration is particularly suitable for sucking in gases emanating from the impregnating agent.
容器壁は有利には垂直である（特許請求の範囲第６項）
。垂直壁から含浸剤は急速に流出する、従って含浸容器
に急速に充填する際にも含浸剤は薄い層に展開される。The container walls are advantageously vertical (claim 6).
. The impregnating agent flows out rapidly from the vertical walls, so that even during rapid filling of the impregnating container, the impregnating agent is spread out in a thin layer.
特許請求の範囲第７項によれば、遮蔽壁は格子上に支持
されている、この場合には含浸剤は遮蔽壁と容器壁との
間にあるガス抜き室の下端で格子を貫流しかつ遮蔽壁の
あらゆる側で含浸容器の有効室内を上昇する。According to claim 7, the shielding wall is supported on a grid, in which case the impregnating agent flows through the grid at the lower end of the venting chamber between the shielding wall and the container wall. Rise inside the effective chamber of the impregnation vessel on all sides of the shielding wall.

有効室４ｂ内に達し、該室内に含浸物１０が存在する。The impregnation container is prepared as follows. With the lid 3 removed, the impregnated material 10 is placed in the still empty container. After closing the container with the lid 3, the air contained therein is largely sucked out, with the gas present in the impregnation 10, for example the air present in the pores, also being removed. Thereafter, the valve 17 is opened to allow the liquid impregnating agent to flow in. The liquid is guided along the walls 1 and 11 and flows down as a thin film along the vaginal wall. The gas dissolved in the impregnating agent 20 passes into the gas phase, first forming bubbles in the liquid which then burst. Gas is drawn in via the suction conduit 6. In the process of flowing downward, the impregnating agent reduces its gas content, which is indicated in the drawing by the bubbles becoming smaller and smaller from top to bottom. The impregnating agent penetrates the grate 9 at the lower end of the vent chamber 12 and then first reaches the chamber 4a below the grate 9. After filling the chamber 4a, the impregnating agent flows through the grid openings into the effective chamber 4b, in which the impregnating material 10 is present.

後続の含浸工程のために再び取出される。The impregnating agent is fed until the impregnated material 10 is completely covered. After the impregnation 10 has been covered, the internal pressure is increased, for example to ambient pressure or even higher. With this pressure increase, the actual impregnation process takes place, since the impregnating agent is forced into the previously degassed pores and the like of the impregnating body 10. After a certain impregnating time, which depends on the impregnant and the impregnating agent, the excess impregnating agent is drawn off by opening the valve 8 and fed into a storage container, from where it is removed again for the subsequent impregnating step.
