摘要： The present invention discloses a dual seal assembly, in particular for sealing a gas compressor, comprising a first mechanical seal assembly (30) including a pair of co-operating seal rings (31, 32), one of which is provided for common rotation with a rotating component (60) and the other of which is provided rotationally fixed at a stationary component (1), a second mechanical seal assembly (40) including a pair of co-operating seal rings (4, 5), one of which is provided for common rotation with a rotating component (60) and the other of which is provided rotationally fixed at a stationary component (1), one of the seal rings being axially movable and axially biased with a biasing force against the respectively other seal ring, said biasing force being transmittable through a force transmitting ring (10) to the respective seal ring, in order to bias facing sliding surfaces (7, 8) of the seal rings, between which a sealing gap is formed during operation, in a mutual sealing engagement, and a secondary sealing assembly (50) for sealing the axially movable seal ring with respect to at least one circumferential guiding surface (16, 18) of a guiding component guiding the movement of the seal ring and the force transmitting ring, wherein the secondary sealing assembly (50) is provided at the force transmitting ring (10) and comprises at least one annular sealing member (13, 13′) made of an elastic material, said member being retained at the force transmitting ring (10) near its periphery and its end face (15) facing the seal ring (4) such that it protrudes beyond the force transmitting ring (10) at least axially and is moldable radially beyond the periphery of the end face (15) due to the effect of the biasing force, such that the annular sealing member (13, 13′) is configured to sealingly engage simultaneously with the seal ring and the circumferential guiding surface (16, 18), whereas such engagement is substantially prevented when no biasing force is effective.

摘要： A dual seal assembly, in particular for sealing a gas compressor, includes a first mechanical seal assembly including a pair of co-operating seal rings, one of which is provided for common rotation with a rotating component and the other of which is provided rotationally fixed at a stationary component. A second mechanical seal assembly includes a pair of co-operating seal rings, one of which is provided for common rotation with a rotating component and the other of which is provided rotationally fixed at a stationary component. One of the seal rings is axially movable and axially biased with a biasing force against the respectively other seal ring to bias facing sliding surfaces of the seal ringss in a mutual sealing engagement. A secondary sealing assembly is provided for sealing the axially movable seal ring with respect to at least one circumferential guiding surface of a guiding component.
摘要翻译：特别是用于密封气体压缩机的双重密封组件包括第一机械密封组件，其包括一对配合的密封环，其中一个密封环设置成与旋转部件共同旋转，另一个设置旋转固定在固定部件。第二机械密封组件包括一对配合的密封环，其中一个密封环被设置成与旋转部件共同旋转，另一个被可旋转地固定在固定部件上。其中一个密封环是轴向可移动的并且以相对于另一个密封环的偏置力轴向偏置，以在相互密封接合中偏压密封环的面对滑动表面。提供了二次密封组件，用于相对于引导部件的至少一个周向引导表面密封可轴向移动的密封环。
