The cooling system operates to optimise turbine blade/casing radial clearances.

The power plant is equipped with electronic engine management and control system of the active radial clearances.

Two parallel disks (3a, 3b) fixed oppositely to the shafts and equipped with at least three arranged with radial clearances concentric grinding hoops (4a, 4b).

The quantity and diameter of the holes (12), as well as their corresponding disposition and the values of radial clearances in shroud crowning seals (4, 5) regulate their efficiency.

The invention relates to an improvement in high-pressure turbines (10) of turbine engines, such as a turbojet, in which a housing (40) for driving the axial clearance of rotary blades (18) is provided.

The invention can be used to ensure friction by means of the longitudinal sliding of both of said elements in relation to one another, eliminating play and radial clearance with total effectiveness in the transmission of torque at any moment.

The cooling system operates to optimise turbine blade/casing radial clearances.

Tyres for light commercial vehicles (LT tyres) Diagonal and radial

The radial bearings can be active magnetic bearings and controlled by two sets of channels in a bearing control system in order to levitate and control the position of the shaft.

According to the invention, by contrast, the radial piston pump is provided with internally supported radial pistons.

The arms (209) can be radial.

In the known engine brake, the radial piston pump has externally supported radial pistons.

The washer includes radial elements that abut corresponding radial elements of the end.

All four tyres must be either radial or non-radial.
