Abstract: A speed changing mechanism includes a pump (1) including a liquid suction channel (6), a liquid drainage channel (8) and working components (3, 4) moving relatively to each other forming working volumes. A relative movement of the working component leads to a periodic increase and decrease of the working volume, so that the fluid is sucked through the liquid suction channel and discharged through the liquid drainage channel, and the pressure energy discharging the fluid is increased by the excursion of the working components. A part of working components is connected to an input component, another part of working components are connected to an output component. The movement of the part of working components relative to another part of working components is changed by changing the flow rate of the pump. Therefore, the speed changing mechanism can realize the switch-on/off of power transmission and change the transmitted power.
