Abstract
A diaphragm machine including a drive unit for producing pulsating hydraulic fluid flows for driving the diaphragms, and a delivery unit for delivering a delivery medium and having pump chambers with volumes that can be varied by the movement of a respective diaphragm. Each pump chamber is connected by a pressure valve to a pressure line and by a suction valve to a suction line. The delivery unit includes at least two hydraulic bodies and a diaphragm body in which the pressure and suction lines are arranged. Each hydraulic body is connected to the drive unit, and formed between each hydraulic body and the diaphragm body is a cavity in which one of the diaphragms is arranged so that by production of the pulsating hydraulic fluid flows, the diaphragms are moved within the cavities and the delivery medium is periodically transferred from the suction line into the pressure line.
