| 摘要 |
<p>The invention relates to an electromagnetic pump with two low pressure chambers, in each of said chambers there being mounted a membrane which may supply a continuous flow rate of fluid. The claimed pump has a tubular body (1) wherein there is located an electric coil (2) wherein a core (3) glides, said core having some resilient membranes (4 and 4.1) fastened to their ends, said membranes operating in counter time in order to supply current to an electric coil (2), a membrane (4) discharges through a valve (8), while the other membrane (4) sucks through another valve (9. 1 upon switching off the current, under the influence of a spring (7), the first membrane (4) sucks through another valve (9), and the second membrane (4.1) discharges through another valve (8.1), the intake valves (9 and 9.1) and the discharging valves (8 and 8.1) are fastened in pairs on some covers (10 and 11) which, together with a central electromagnet, form a packet clamped by means of some dowel pins (12) and nuts (13).</p> |
