A sealing device (10) for providing a fluid-tight sealing of a joint comprising a first part (30) and a second part (32) with a relative movement in between. The sealing device (10) comprises: an outer sealing part (12) designed to contact the first part and the second part, an inner sealing part (14) designed to contact the first part and the second part, and a spacing structure (16) connecting the outer sealing part (12) and the inner sealing part (14). The outer sealing part (12) and the inner sealing part (14) define an intermediate space (18) between the outer sealing part (12) and the inner sealing part (14). The outer sealing part (12) and the inner sealing part (14) are being configured to seal off the intermediate space (18) from both an exterior and an interior of the joint, and the intermediate space (18) is configured to be in fluid contact with both the first part (30) and the second part (32).
A robot comprising at least one joint and a sealing device for providing a fluid-tight sealing of the joint wherein the joint has a first part and a second part with a relative movement in between, the sealing device comprising:
The robot according to claim 23, wherein the spacing divide the annular intermediate space into two annular spaces, and wherein the flow channels fluidly connect the two annular spaces.
