FLUEGELZELLENVERDICHTER

摘要

In a cellular blower with vanes (28) guided in radially extended longitudinal slots (27) in the rotor (18) which divide at least one operative chamber (21, 22) formed between the inner wall (17) of a recess (14) in the casing into low and high-pressure cells (30-33), in order to achieve a uniform temperature distribution throughout the blower, inlet apertures (34-36) are allocated to the low-pressure cells (30, 31) and arranged at opposite sides of the low-pressure cells (30, 31) so that the recooled coolant enters each low-pressure cell (30, 31) axially in opposite directions of flow. The inflow channels (38-40) opening into the inlet apertures (34-36) are of equal lengths and arranged symmetrically to the rotor spindle. The inflow channels (38 or 39, 40) which open into inlet apertures (34 or 35, 36) located on the same side branch off from an inflow chamber (41, 42). The inflow chambers (41, 42) are arranged coaxially to the rotor spindle and are preferably connected together via the hollow rotor spindle (20).
