The invention relates to a regulator related to a motor- driven pump for regulating of outlet pressure according to a predetermined value. By means of the invention, an automatically functioning and reliable regulation according to a predetermined value is provided, in order to prevent cavitation and diminish the risk of broken liquid flow in the pump. This is enabled by a double diaphragm 12 communicating with a means acting for the pump for regulating the capacity of the driving source via a preferably spring force loaded movement transmitting means 4, 10, and communicating with the output pressure 30 from the pump via a compartment 27 between the diaphragms 12A, 12B in said double diaphragm 12, for action on the double diaphragm 12 for adjusting the capacity regulating means to a desired degree, whereby an increased or decreased fluid outlet, respectively, from the pump provides a displacement of the double membrane 12 towards the maximum or minimum position, Fig. 4, respectively, of same. <IMAGE> |
