A pneumatic turbine, comprising a turbine wheel (13) with a peripheral row of blades (14) and a stator housing (10) having nozzles (11) for directing motive air at high speed onto the blades (14) to rotate the turbine wheel (13), an exhaust passage (15) located downstream the turbine wheel (13), and a particle escape passage (20) located on the same side of the turbine wheel (13) as the air nozzles (11) to drain from the turbine harmful particles and, thereby, avoid a blasting effect of such particles on the turbine wheel blades (14). <IMAGE> |
