The hydrostatic balance is built between the con-rod and eccentric sets, solve the problem of higher-power hydraulic motor of shaft con-rod be overwhelmed by the roller, so this motor have higher pressure, higher speed, higher power.
Using special treatment process and hydrostatic balance between the con-rod and piston, reduce the friction loss in the load transmission, reduce the force between piston and cylinder wall, then reduce the friction loss between the piston and cylinder wall.
The piston seal ring using special structures to reduce the friction and improve the volumetric efficiency.
Using the hydrostatic balance shaft distributor, the distributor can rotary without connection, improve the volumetric efficiency and reduce the noise and the resistence.
Characteristics and data is similar with Staffa.
