PNEUMATICALLY POWERED POLE SAW |
| 摘要 |
A pneumatic valve assembly with a trigger for switching the pneumatic valve assembly between two or more valve operation modes is disclosed herein. The valve operational modes are determined by selection of fluid conduits by a trigger valve assembly of the pneumatic valve assembly which interconnects fluid conduits to a main valve, pilot valves and a pneumatic cylinder of a fluid powered pole saw and wherein a piston located in the pneumatic cylinder is mechanically coupled to a cutting blade of the pole saw and the trigger is operatively coupled to the trigger valve assembly. |

1. A pneumatic valve assembly with a trigger for switching the pneumatic valve assembly between two or more valve operation modes, the valve operational modes are determined by selection of fluid conduits by a trigger valve assembly of the pneumatic valve assembly which interconnects fluid conduits to a main valve, pilot valves and a pneumatic cylinder of a fluid powered pole saw and wherein a piston located in the pneumatic cylinder is mechanically coupled to a cutting blade of the pole saw and the trigger is operatively coupled to the trigger valve assembly. |
