Abstract

A rotary piston pump equipped with a motor having two counter-rotating rotary pistons. The two rotary pistons are housed in an oval pump housing. The two rotary pistons are arranged on a first output shaft and a second output shaft. The first output shaft and the second output shaft are driven and synchronized via at least one elastic element.
