The encircling device has an inlet (22) at the end of the handle closest to the casing, formed by a breach in the handle wall coming out into an annular cavity (23) round the end region of the transmission (19) closest to the casing and sealed to the casing-side end of the handle. There are grooves (25) running along the transmission to the air inlet (26) of the rotor (18) and connecting up to the annular cavity.
