Features:
1. Adopt eccentric shaft and a lower vibration frequency of the five piston structure, has the characteristics of low noise;
2. Large starting torque, low speed stability is good, it can operate at very low speed smoothly;
Plane to compensate the oil distribution disc 3., good reliability, less leakage; Piston and the plunger sleeve adopts sealing ring seal, thus has the very high volumetric efficiency;
4. Between the crankshaft and connecting rod by roller bearing, therefore has the very high mechanical efficiency;
5. The direction of rotation reversible, output shaft allows absorb a certain amount of radial and axial force;
6. Has the high power mass ratio, volume weight is relatively small.
