<p>PURPOSE:To restrain the over compression of a compression chamber, by arranging co-polar magnets in mutual opposition at the respective center portions of a pair of scrolls. CONSTITUTION:The circle arc 2f of a scroll projecting body 2a makes a relative displacement as it opposes the inside curved line 1g of a scroll projecting body 1a, by the relative turning of both scroll projecting bodies 1a, 2a, and a compression chamber A is compressed. Hereupon, a permanent magnet 2j at the circle arc 2f opposes a permanent magnet 1j at a circle arc 1h, and then, repelling power is acted on between the circle arc 1h of the scroll projecting body 1a and the circle arc 2f of the scroll projecting body 2a, and a minute space is formed, and the compression chamber A which has become highly pressured communicates with the next compression chamber B where pressure is comparatively low, and the over compression of the compression chamber A is restrained as the pressure of the compression chamber A escapes into the compression chamber B.</p> |
