摘要： A membrane fluid pump includes a rotatable drive shaft. The shaft is equipped with a number of eccentrics arranged axially along the shaft. The membrane fluid pump further comprises a set of connecting rods connected to each of the eccentrics. Each connecting rod is attached between one of the eccentrics on the shaft and a corresponding membrane so that each of the connecting rods is arranged to transfer a rotating movement of the shaft to a reciprocating movement pattern of the corresponding membrane. Each of the eccentrics and the connecting rods are arranged such that all of the membranes will reciprocate with a phase shift evenly distributed over a 360 degree rotation of the drive shaft, and wherein all of the eccentrics are rotationally offset to each other with an angle so that they are evenly distributed over a 360 degree rotation of the drive shaft.
