A retarder ( 100 ) including a stator ( 170 ) and/or a housing ( 102 ) surrounding or encasing a rotor ( 101 ), a mechanism ( 140 - 142 ) for producing an air current and at least one inlet ( 120 ) enabling air current to enter and at least one outlet ( 120 ) used to evacuate the air current. The outlet ( 121 - 123 ) is created between two cooling chambers ( 111 - 112 ) or through several cooling chambers which are borne by the housing and/or stator of the retarder.
