ABSTRACT:
A peripheral blower of the kind having a toroidal chamber which is divided along a plane at right angles to its axis into a chamber part bounded by a stator housing having adjacent inlet and outlet ports with a stripper between them, and a chamber part bounded by a rotor housing containing a series of impeller blades, characterized in that the stripper block has a central cross-section corresponding to the cross-section of the hemi-toroidal stator in which it is fixed, and also two shaped vanes projecting one from each end of the block and extending in opposite directions around the toroidal chamber so that they at least partially cover the inlet and outlet ports, the thickness of each vane gradually diminishing from its root connection with the block to its free tip end. The blower is further characterized in that the stator housing is provided with passages which lead to and from the inlet and outlet ports respectively, the center lines of which are directed substantially along the directions of the helical path of the air-flow at the respective ports.
