<p>Diaphragm pump operated by pressurised fluid has the first chamber connected to an inlet and an outlet valve and the second to a cyclic pressure fluid feed with a monostable working unit whose inlet duct connects to the fluid guide and with 2 outlet ducts, one to the pump's second chamber and the other to the atm. One of the 2 control channels of the monostable fluidic element is connected to the feed channel via a resistance; the other, which is at the side of the outlet channel leading to the pump, is connected to a first control opening in the mid part of the base of the second chamber and closed by the diaphragm at the end of the suction phase of the pump.</p> |
