PCT No. PCT/SE82/00169 Sec. 371 Date Jan. 12, 1984 Sec. 102(e) Date Jan. 12, 1984 PCT Filed May 13, 1982 PCT Pub. No. WO83/04074 PCT Pub. Date Nov. 24, 1983.Regulator in a motor driven pump for the regulation of the output pressure according to a predetermined value. An automatically functioning reliable regulation according to a predetermined value in order to impede cavitation and reduce the risk of an interrupted flow of liquid in the pump is provided by means of the invention. This is made possible by means of a double diaphragm (12) via a preferably spring biased transmission means (4, 10) of movement being in connection with a controlling means serving the purpose to control the capacity of the power source of the pump and with a space (27) between the diaphragm elements (12A, 12B) of said double diaphragm (12) being connected with the output pressure (30) from the pump for the actuation of the double diaphragm (12) in order to adjust the controlling means of the capacity in a desired degree, and increased or decreased fluid output from the pump bringing about a displacement of the double diaphragm (12) to its maximum position (FIG. 4) or minimum position (FIG. 5) respectively. |
