Rotary piston pump and method for operating a rotary piston pump

摘要

The invention relates to a rotary piston pump (20) which comprises at least one motor (22) having at least two counter-rotating rotary pistons (32). The at least two rotary pistons (32) are housed in an oval pump housing (26). The at least two rotary pistons (32) are arranged on a first output shaft (40) and a second output shaft (41). The first output shaft (40) and the second output shaft (41) are driven and synchronized via at least one elastic element (44).
