Power cylinder with embedded solenoid valve

A power cylinder with embedded solenoid valve, comprising:

• a cylinder body having a first end and an opposite second end, the cylinder body comprising a chamber therein;
• a piston assembly movably disposed in the chamber of the cylinder body;
• a top cover disposed on the first end of the cylinder body, the top cover having an inlet, two outlets, a movement bore, a first passage, and a second passage, the inlet and the two outlets being in communication with the movement bore, respectively, so that a fluid enters the chamber through the inlet, wherein a plurality of operation channels are concavely disposed at intervals on a periphery of an inner diameter of the movement bore, the operation channels are in positional alignment and communication with the inlet, the two outlets, the first passage, and the second passage, respectively, and the second passage is in communication with the chamber;
• a bottom cover disposed on the second end of the cylinder body, the bottom cover comprising a third passage in communication with the first passage and the chamber;
• and
• a solenoid valve disposed on the top cover, the solenoid valve comprising an electronic control unit and a valve stem, the valve stem disposed in the movement bore, the electronic control unit controlling the valve stem to reciprocate between a first position and a second position, wherein when the electronic control unit controls the valve stem to be located at the first position, the inlet is in communication with two of the operation channels, the first passage, the third passage, and the chamber, and the fluid pushes the piston assembly toward the top cover;
• when the electronic control unit controls the valve stem to move to the second position, the inlet is in communication with other two of the operation channels, the second passage, and the chamber, and one of the two outlets is in communication with another one of the operation channels, the first passage, the third passage, and the chamber, and the fluid pushes the piston assembly away from the top cover, and the fluid originally located in the chamber is outputted from one of the two outlets through the third passage and the first passage.
