Title:
DRAGONFLY-WING-SHAPED BLADE, BLADE WITH J-SHAPED CROSS SECTION, AND BLADE WITH BACK-TO-BACK J-SHAPED CROSS SECTION, FOR USE IN SHROUD-EQUIPPED ROTARY VANE MECHANISM, LINEAR BLOWER, OR LINEAR WIND-POWERED GENERATOR
Document Type and Number:
WIPO Patent Application WO/2014/030465
Kind Code:
A1
Abstract:
Heretofore it has been difficult with conventional methods to manufacture a rotary vane with a large diameter for use in a shroud-equipped rotary vane mechanism, a linear blower, or a linear wind-powered generator, and those which can be manufactured are extremely expensive, and therefore are difficult to sell. In the present invention a rotary vane for use in a shroud-equipped rotary vane mechanism, a linear blower, or a linear wind-powered generator, is formed by means of a dragonfly-wing-shaped blade formed with a tread surface, a rise surface, and a slope (an inclined surface) and constructed so as to have a stepped cross section in the blade width (blade chord) direction; or is formed by means of a blade having a J-shaped cross section and constructed with only a rise surface having a rising length and a slope (an inclined surface), with the tread surface forming the dragonfly-wing-shaped blade being omitted; or is formed by means of a blade having a back-to-back J-shaped cross section and constructed by placing back-to-back two blades having a J-shaped cross section.
