[Also in Division F2] The invention relates to a turbo-charger in which means are provided for holding the turbine and compressor assembly stationary until the pressure of the lubricating oil of the main engine has reached a predetermined value. The brake device is shown in Fig. 2 in which the turbine and compressor shaft is indicated at 42. A pair of members 130, 132 are secured together and to the housing member 22 by means of bolts 134. The members 130, 132 define a chamber 149 in which is disposed a piston member 138 which is acted on at its left-hand side by a spring member 158 whereby the piston 138 and the member 146 integral therewith are urged to the right, the member 146 engaging against a brake member 160 secured to the shaft 42. The brake is released once the pressure of the engine lubricating oil has reached a predetermined value, the oil passing through duct 150 and opening the ball valve 156 against the loading of spring 157, thence into the chamber 149 to move the piston 138 and brake member 146 to the left against the loading of spring 158.
