Abstract: A leak resistant, switching, double valve system consists of two sliding valve bodies in a valve housing with connecting lines. The two sliding valve bodies, which can be actuated independently of one another, are in contact in the closed position with valve seats in the valve housing, and are located at some distance one behind the other, forming a leak cavity between them. During the opening process, the first sliding valve body, before it leaves its valve seat, while simultaneously reducing the size of the leak cavity, can be placed in contact with the second sliding valve body, which is provided with a tubular extension which exits the valve housing in a sealed manner and connects the leak cavity to the environment of the valve system.

Abstract: An arrangement for connecting two parts of a fluid system, preferably an aseptic system, by which the pressure gradient acts from the outside to the inside. The one system part carries an O-ring in a groove open to the other system part and open radially outwardly and the other system part is pressed against the O-ring by an axial holding device. To avoid dead space, in which bacteria could deposit, a space formed by the O-ring, the two system parts and the axial holding device is provided with a communication to the surroundings.
