Abstract: The invention is connected with an installation or plant for storing oil and similar petrol products in several underground storing rooms each communicating with a common oil-filled pump chamber housing submersed pumps for pumping out oil from any of the rooms. Selective pumping requires valves for selective connection of room outlet pipes with a pump inlet pipe. Submersed location of those valves in the pump chamber, according to the prior art, involves several disadvantages such as the need of draining the complete system for repair and maintenance work on the valves, and, difficulty to remote-control the valves. These advantages are, according to the invention, eliminated by the use of a dry valve chamber sealed-off from an oil-containing pump chamber housing submersed pumps.

Abstract translation: 本发明与用于在几个地下储存室中储存油和类似汽油产品的装置或设备连接，每个地下储存室与普通的装有油的泵室连通，该泵室容纳浸没泵，用于从任何房间抽出油。 选择性泵送需要阀门，用于选择性连接室内出口管道和泵入口管道。 根据现有技术，这些阀在泵室中的浸没位置涉及若干缺点，例如需要排出整个系统以对阀门进行维修和维护工作，并且难以远程控制阀门。 根据本发明，这些优点通过使用从包含浸没泵的含油泵室封闭的干阀室来消除。
