Abstract: A connection system comprising: a dispensing member; a receiving member; first sealing means and second sealing means arranged at the interface between the dispensing member and the receiving member to enable redundant leak-tight engagement between the dispensing member and the receiving member; a control chamber defined between the first sealing means and the second sealing means; and means for measuring the current pressure in the control chamber so as to detect a gas leak.

Abstract: A turbomachine air starter, including a first compartment wherein non-overrunning elements of the air starter are situated, corresponding to elements which are only run in the turbomachine starting phase, and a second compartment wherein overrunning elements of the air starter are situated, corresponding to the elements which are run throughout an operating time of the turbomachine, including the starting phase. The first compartment includes an oil receptacle for oil splash lubrication of the non-overrunning elements, and the second compartment includes an AWC type oil cavity for lubrication of the overrunning elements supplied by the lubrication oil return of the overrunning elements, in turn supplied with pressurized lubrication oil supplied by the turbomachine, the receptacle and the cavity being internal to the air starter.
