Abstract (en)
[origin: EP0480192A1] Double-diaphragm pump with diaphragms dividing two diaphragm chambers and connected to one another by a connecting rod (22), a control slide valve (12) with sealing elements (13), displaceable as a function of the position of the diaphragms (24), for alternately opening and covering control ducts (2, 3, 4, 5, 6) arranged in a control slide valve housing (1) for alternately admitting propellant to a propellant chamber and relieving it of this, and an actuating element (16, 17; 22, 28) coupled to the diaphragm movement and magnetically to the control slide valve. <IMAGE>
