<p>PURPOSE: Bellows for compressing or squeeze pumping air are provided to prevent energy loss and low efficiency by minimizing the occurrence of air gaps and closely contact a disk core with internal filling members which are inserted into internal grooves at the end-stage of contraction of the bellows. CONSTITUTION: Bellows for compressing or squeeze pumping air comprises a plurality of internal filling members(130) and a filling block(140). The internal filling members are inserted into the internal grooves of corrugated parts which are formed due to the combination of disk cores(110). The internal filling members are ring-shaped and extended along the circumference of the bellows. The filling block is installed inside the bellows in order to reduce the increased internal volume of the bellows caused by the insertion of the internal filling members.</p> |
