Subject: as it would have to пожалуйста, скажите, правильно ли я перевела 2 предложение. Спасибо.
Furthermore, if the membrane pumps 13a, 13b (Fig. 2) are connected to the same source, the pressure in this source will act on both sides of the driving arrangement, that is on left and right, respectively, side of the first and the second piston 21a, 21b. Thus, the electric motor does not need to work against a constant counter pressure, as it would have to if it only operated one piston
Таким образом, электродвигатель не должен работать при постоянном противодавлении, как он должен был бы работать при одном поршне
