| 摘要 |
The present invention is directed to an impact driver, which relies on multiple connected piston and cylinder assemblies which sequentially fire; a first auxiliary piston assembly charged to compress a compressible fluid with a piston rapidly releases the charge on said piston allowing the compressed fluid, which is typically a gas, to accelerate said auxiliary piston. This auxiliary piston is connected to a second travelling primaty piston assembly which it accelerates. Within the primary piston assembly a primary piston can be charged to compress a compressible fluid. The charge on the primary piston can also be rapidly released to accelerate the primary piston. The primary piston may be connected to a striking element, or successive travelling piston and cylinder assemblies which ultimately connect to a striking element. |
