Method and Device for Automatically Conveying Liquids of Gases

Abstract

Disclosed is a device for conveying liquid and/or gaseous media, comprising at least two pumping chambers whose volumes change periodically during operation. Each pumping chamber is provided with at least one intake and discharge valve while all pumping chambers are fitted with a common main inlet and a common main outlet. A drive unit which is configured such that the volumes of the pumping chambers change at a phase shift of 2π/number of chambers is allocated to the pumping chambers. Also disclosed is a device for conveying liquid and/or gaseous media, comprising at least two pumping chambers whose volumes change periodically during operation. Said pumping chambers are embodied and disposed such that at least two adjacent pumping chambers encompass a joint wall which is configured so as to modify the volume of the adjacent pumping chambers. The invention further relates to a method for conveying liquid and/or gaseous media with the aid of the disclosed device. The device is triggered in such a way that the volumes of the pumping chambers change at a phase shift of 2π/number of chambers.
