进油管路确保两个止回阀的流量相等：首先，尝试使可移动框架位于两个气缸的

In-line <br>to ensure that the two check valves of equal flow: <br>First, try the movable frame geometric center of the two cylinders located <br>Next, piston and piston rod manufacturing aspects. Mechanical damping between the piston rod and the end cap to ensure that the mechanical damping of two similar piston-cylinder similar to the cylinder when the rapid decline.

Inlet line<br>Make sure that the flow of the two check valves is equal:<br>First, try to place the movable frame at the geometric center of both cylinders<br>Second, the manufacture of pistons and piston rods. The mechanical damping between the piston rod and the end cap is similar to ensure that the mechanical damping of the two piston cylinders is similar when the cylinder slowers rapidly.

Intake line<br>Make sure that the flow of the two check valves is equal:<br>First, try to position the movable frame at the geometric center of both cylinders<br>Secondly, manufacturing piston and piston rod. The mechanical damping between the piston rod and the end cover is similar to ensure that the mechanical damping of the two piston cylinders is similar when the cylinder drops rapidly.
