Estimating the term…
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.
A rotary piston pump with at least one motor with at least two counter-rotating rotary pistons and a pump housing, wherein the at least two rotary pistons are disposed on a first output shaft and a second output shaft and wherein the first output shaft and the second output shaft are synchronised and driven in such a way that the at least two rotary pistons engage into one another, characterised in that the rotary pistons are connected to one another at the drive side via at least one elastic element.
A method for the operation of a rotary piston pump with at least one motor with at least two counter-rotating rotary pistons and a pump housing, wherein the at least two rotary pistons are disposed on a first output shaft and a second output shaft and wherein the first output shaft and the second output shaft are synchronised and driven in such a way that the at least two rotary pistons engage into one another, characterised in that the rotary pistons are connected to one another at the drive side via at least one elastic element, and that the first output shaft and the second output shaft are driven and simultaneously synchronised by means of at least one motor via at least one elastic element.
