Abstract

A pump (10) with a double-effect valve, especially a vibration type valve with oscillating plunger or piston (20) from ferromagnetic material, included in a container (12) circumscribed by a bobbin (14) with the related bushings (16) and magnetic spacer (18), cooperating with a first valve (22) abutting along the delivery duct obtained in the hollow front body (28), and with a second valve (24) located along the suction duct (48), said first (22) and said second valves (24) being spaced out by a mobile spacer or lid (26), and said second valve (24) being so located as to strike on the upper part said spacer (26) and in the lower part the upper mouth of piston (20). <IMAGE>
