Abstract
Provided is a series-connection type servo valve mechanism. The mechanism includes: a drive motor, a first valve seat, and a second valve seat, a first guide block, a first eccentric wheel, a second guide block, a second eccentric wheel, a first eccentric shaft, a second eccentric shaft, a first valve core seat, a second valve core seat, a first valve core, a second valve core, a first valve rod, a second valve rod, a first valve core plug, and a second valve core plug. The first guide block is capable of driving the first valve core plug through the first valve rod to move and cooperating with the first valve core to open or close an internal channel of the first valve core seat.
