|
| Features |
1. Light weight, compact design
Various components such as the motor housing and reduction gear cover, and the cylinder and shaft have been combined and integrated into a single type construction for decreased weight and size. |
2. Highly reliable and long life
Supported by the cylinder block, the cylinder block is rigidly constructed for virtually no effects from external vibration and hydraulic pressure fluctuations. |
3. Quiet operation
Virtually noise free operation due to highly rigid-type cylinder block and shaft. |
4. Highly efficient operation with outstanding self-priming capability
Enlarged oil path and reduced stress between the piston and the shoe due to optimum oil path in the valve plate. |
5. Improved operability
Virtually leak-proof with improved fine-movement operations |
