带有密封装置的设备
摘要：
本实用新型涉及一种带有密封装置的设备。为了实现有效密封，该设备包括一种具有围绕中心开口大致以环形配置布置的多个密封元件（2″″）的密封装置。每个密封元件包括面向中心开口的密封表面。包括至少一个用于接纳密封元件（2″″）的部段的腔室（13″″）。通向流体源的入口为至少一个腔室（13″″）供应流体以便产生超压力，该超压力作用在密封元件的接纳在至少一个腔室（13″″）内的部段上，并且用于按压密封元件的密封表面并且使所述密封表面朝向中心开口运动。
摘要（英）：

The utility model relates to equipment provided with a sealing device. In order to realize effective sealing, the equipment comprises the sealing device which is provided with a plurality of sealing elements (2''''), wherein the sealing elements are roughly arranged in a ring shape around a central opening. Each sealing element comprises a sealing surface facing the central opening. The sealing device further comprises at least one cavity (13'''') used for containing segments of the sealing elements (2''''). An inlet leading to a fluid source supplies fluid to at least one cavity (13'''') so as to generate superpressure. The superpressure acts on the segments, contained in the cavity (13''''), of the sealing elements and is used for pressing the sealing surfaces of the sealing elements and enabling the sealing surfaces to move toward the central opening.
