PNEUMATIC PERCUSSIVE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a percussive system used even in a ferromagnetic field. SOLUTION: This percussive system includes a floating plunger caused to reciprocate by a pneumatic spring. The floating plunger strikes the front end face of a percussive tool stored in a tool holder directly or through a striker disposed in a space up to the percussive tool. An integral formed floating plunger and/or striker is formed of non-ferromagnetic material, preferably curable material. COPYRIGHT: (C)2004,JPO
