| 摘要 |
<p>The invention relates to a pump with a direct thrust recovery device for driving fluids, formed by pumping mechanisms formed by pistons (4) which are actuated in reciprocating longitudinal movement, the corresponding piston (4) playing in each pumping mechanism between two chambers (6 and 7), through one of which the passage of the fluid to be pumped is established, whereas in the other chamber the reject flow of the applied system enters and exits, such that said reject flow acts to directly thrust the piston (4), exerting a complementary action of the drive thereof.</p> |
