摘要: A high pressure swivel includes an inner and an outer wall. Each annular wall is connected to a respective distribution member via apertures which have an axial dimension which is smaller than the diameter of the inlet or outlet. In this way, the pressure area between the seals of the inner and outer rotatable walls is reduced. Each distribution member may include a chamber that is defined by the external surface of the inner and outer annular walls, and an enclosing wall. In this way, an effective thermal isolation is provided by the distribution chambers adjacent to the external surfaces of the inner and outer rings. Deformation of the distribution chambers of the swivel will tend to decrease the width of the seal extrusion gap.
