    摘要： An electromagnetic percussion device, which includes a housing and an instrument which is connected to, and which extends beyond, the housing. The device further includes a piston body reciprocatable within the housing and adapted to impact the instrument. The piston body includes an intermediate region of a first diameter and an enlarged posterior head of a second diameter, with the second diameter being larger than the first diameter. The device also includes a driving member reciprocatable within the housing. The driving member includes a coupling element for slidably accommodating the head of the piston body, thereby coupling the driving member and the piston body together. A permanent magnet is connected to the driving member. Finally, an electromagnet coil is connected to the housing, the coil being operationally coupled to the permanent magnet so as to cause the reciprocation of the driving member.

    摘要： A percussive tool, for use in mining, quarrying, or excavating, comprising a reciprocable mass movable in one direction against the resistance of a spring by a movable permanent magnet assembly. A hydraulic ram moves the permanent magnet assembly. A plate between the ram and the magnet assembly acts as a flux diverter such that as the assembly is moved proximate the plate by the ram, flux passing through the mass is reduced and the spring forces the mass to impact a tool shank.
