摘要

Hydraulic mechanism compound between the other of a turbine with two rotors to the dynamic performances are improved by virtue of two internal chambers acting inversely in compression and decompression (figure 2). Hydraulic mechanism actuated by a fluid under pressure. This hydraulic mechanism is associated with a bypass permitting the supply of fluid under pressure in the case or flow rate and pressure are insufficient. The hydraulic mechanism according to the invention is particularly intended to improve the performance of a mechanical demultiplication actuating synchronously a rotary pump.
