<p>The jet engine has a shaft (14) driven by a turbine (12) superimposed outside the shaft, which is supported by a rear rolling bearing (20) situated between the shaft and the turbine. The rolling bearing is housed in a lubricating chamber (24), which maintains oil mist. The chamber has an inner rotating part and an outer fixed part separated by a seal (40). A pressurized recovery chamber (26) surrounds the lubricating chamber and comprises another seal (48) situated radially with respect to the seal (40), where the seal (48) is situated downstream from a rotor (28) of the turbine.</p> |
