电磁式冲击驱动器
摘要：
本发明涉及用于需直线运动的工具的电磁式冲击驱动器，其具有下列特征：a)两个可导电的和相互交错的螺旋弹簧以它们的两个固定端部支撑在支座上并且以它们的可运动的端部与一个共同的可导电的衔铁接合，该衔铁与可直线运动的推杆连接；b)螺旋弹簧的可运动的端部经由衔铁而导电地相互连接；c)螺旋弹簧的固定端部为了引入电流强度经由电气端子而与可控制的电源连接，该电流强度从一个电气端子起经过螺旋弹簧沿第一方向流向衔铁并且从那里沿相反的第二方向经过第二螺旋弹簧流回另外的电气端子，因而两个螺旋弹簧的相邻的线圈在接通的电路中经历作为推斥的反向定向的力偶；d)控制装置构造成用于将电路与电源断开和接通。
摘要（英）：

An electromagnetic impact drive includes two electroconductive helical springs in meshing relationship, with their fixed ends supported on an abutment and their movable ends joined to an electroconductive armature. Electric terminals connect the fixed ends to a electricity source for feeding a current to flow from one of the electric terminals via an associated one of the helical springs in a first direction towards the armature and from there in an opposite second direction via the other one of the helical springs to the other one of the electric terminals so that adjacent windings of the helical springs repel one another by an oppositely directed force pair when an electric circuit is closed. A control device is provided to open and close the electric circuit with the electricity source.
