Abstract : An apparatus is described in the patent for maintaining a pressure differential across an aperture between two volumes of different pressure having a circular impeller within a chamber of a circular housing with the outer circular wall of the housing being spaced a predetermined distance from the periphery of the impeller. The circular chamber is positioned between two volumes at different pressures. The differential pressure between the volumes turns the gas flow back in the direction of the low pressure volume.
