Abstract

A pressure compensation valve for a dialysis machine is disclosed. The pressure compensation valve has a valve housing, in which a flow path with fresh dialysate is separated from a flow path with exhausted dialysate by a diaphragm. The diaphragm and the valve housing are configured such that pressure compensation is possible. In addition, the diaphragm is configured such that no vibrations or a reduced amount of vibrations and/or no noise emission or a reduced amount of noise emission will occur during operation. Furthermore, a dialysis machine comprising such a pressure compensation valve is disclosed. The dialysis machine comprises a balancing unit, and the pressure compensation valve is arranged on the outlet side of the balancing unit.
