A diffuser-nozzle assembly for mounting at an outlet from a compressor in a turbomachine, the assembly including a nozzle including two substantially cylindrical walls, a radially inner wall and a radially outer wall that are connected together by radial vanes. The walls of the nozzle are extended downstream beyond the radial vanes and the radial spacing therebetween varies downstream from the vanes to be at a minimum substantially in register with the vanes and at a maximum between the vanes.

A compressor nozzle ring for an aircraft includes an inner shroud, an outer shroud and a multiplicity of blades extending from the inner shroud to the outer shroud. Each blade passes through the inner shroud and is attached to it with sealing cement containing an organic polymer adhesive. The adhesive is polyimide based.

A device for controlling variable-pitch vanes in a turbomachine has rods each having at one end a finger for mounting in a control ring and at its other end an assembly orifice for mounting on a drive square of a vane, the axis of the vane being inclined relative to the axis of the finger of the rod, and the assembly orifice in the rod presenting a dimension in the longitudinal direction of the rod that is greater than that of the drive square, and co-operating therewith to define clearance that varies over the height of the drive square and of the orifice.
