Example Embodiment
[0061] Reference Figure 1 to Figure 22b , Floating two-dimensional dual piston pump, including a pump body 2. The pump body 2 is provided with an oil suction port and an oil discharge port. The pump body 1 is provided with a pump unit, which is characterized by:
[0062] The pump unit includes two cylinders 4, 10 fixed in the pump body. The two cylinders 4, 10 are arranged on the left and right. Both cylinders are provided with pistons 15, 11, and the two pistons are linked with each other; the central axis of the cylinder is The central axis of the piston coincides, both ends of the piston are provided with moving members that drive the piston to move axially to cause the volume of the working chamber to change, and the moving directions of the moving members at both ends of the piston are opposite when the piston is driven to move;
[0063] The working chamber includes a left chamber and a right chamber located at both ends of the cylinder body 4 and 10, respectively. Ring-shape...
