Abstract
A motor-driven continuously running system wherein multiple reciprocating bellows units are disposed in angularly spaced relation about the rotary axis of a swashplate. Each bellows is frame-referenced at one end, and its other end is axially driven by the swashplate. As the bellows units reciprocate in phased succession, air is driven into and expelled through a valve/manifold unit, which channels air to and from outlet and inlet fittings, via integrally formed reed check valves. The output is a steady flow of contamination-free pressurized air.
