Reversible electromagnetic valve

A reversible electromagnetic valve, comprising a valve seat having a valve port, a slider slidably connected to the valve seat, and a driving member;

• wherein the driving member is capable of driving the slider to move in contact with the valve seat, resulting in a sealing surface of the slider configured to selectively block the valve port;
• and
• the sealing surface of the slider has a sealing point, the sealing point of the sealing surface is provided corresponding to a limit position of an edge of the valve port of the valve seat, such that when the slider drives the sealing point to cross the valve port, the sealing surface of the slider is capable of blocking the valve port;
• and under action of a pressure difference, a position where the sealing point of the sealing surface is located is not lower than a plane where the edge of the valve port is located;
• the reversible electromagnetic valve further comprises a valve body and a valve core assembly;
• the valve core assembly comprises the slider and a piston, and the valve body has a valve cavity in which the valve core assembly is capable of moving;
• an intermediate end cap is provided in the valve cavity, a first end cap and a second end cap are provided at two ends of the valve body, respectively;
• and the valve cavity comprises a first chamber, a second chamber, and a third chamber;
• and
• the first chamber is defined by the first end cap, the valve body, and the valve core assembly;
• the second chamber is defined by the valve core assembly, the intermediate end cap, and the valve body;
• and the third chamber is defined by the valve core assembly, the valve body, and the second end cap.
