A first laminate at a first end of the central core is provided having a first orifice defining a first diameter and a second laminate at a second end of the central core is provided having a second orifice defining a second diameter that is the same as the first diameter. A flow line passes through the central core and is configured to extend from the first laminate to the second laminate, the flow line defining a third diameter that is larger than the first and second diameters. The first and second diameters are configured such that air flow is permitted to pass through the first and second laminates and to restrict the flow of a liquid through the first and second laminates.

Abstract: A centrifugal multiblade blower includes: an electric motor; and an impeller blowing off air outward in a radial direction by being rotated by the electric motor. A main plate of the impeller has an uneven part on one surface adjacent to the electric motor in a thickness direction of the main plate. The one surface is in contact with air passing through inside of the electric motor. A surface shape of the uneven part is formed in manner that, among a whole surface of the uneven part, a total surface area of a surface facing inward in a radial direction of the motor is larger than an imaginary smooth surface on which the surface shape of the uneven part is defined to be a smooth surface without the uneven part.

Abstract: A brushed rotatory device (10) includes a stator, a rotor (14), an impeller (70), and a chamber (48) accommodating the commutator (16) and brushes (52) to contain debris from consumed brushes. The impeller causes air flow to dissipate heat generated by the rotatory device and may further carry the consumed brush debris away. The rotatory device includes flow channel(s) (72) which communicates with the impeller exhaust and accommodates absorbent or filtering materials (88) to trap the debris in the air flow. The commutation area may be double contained by using flange(s) (202) or wall(s) (42) to trap or confine a greater part of the debris in a localized region or to reduce noise from the rotatory device operations.
