无阀型液压凿岩机冲击器是自动配流式液压冲击器的一种结构型式,目前在国内外正在进行研制工作。它靠活塞本身的运动,通过位移反馈,将直流液流转换为交变液流交替进入油缸两容腔而实现活塞连续往复时冲击振动;同时,它还利用油液的微量可压缩性,在工作容 Valveless hydraulic rock hammer Impactor is a type of automatic hydraulic flow impact device, is currently under development at home and abroad. It relies on the movement of the piston itself, through the displacement feedback, the DC flow is converted to alternating flow alternately into the cylinder two chambers to achieve continuous piston reciprocating shock vibration; the same time, it also uses the micro-fluid compressibility, at Work capacity
