Abstract

A delivery device for supplying a respirator with breathing gas includes a cylinder housing with a piston, and a drive unit for generating delivery strokes, which is connected to the piston via a piston rod. A compact design is achieved by providing the drive unit with a motor-driven hollow shaft with a spindle acting as a piston rod displaceable in it telescopically.
