Hydraulic hammer having dual valve acceleration control system

The invention relates to a hydraulic hammer having a dual valve acceleration control system. The hydraulic hammer may have a housing and a piston configured to reciprocate within the housing. The hydraulic hammer may also have an acceleration channel formed within the housing. The acceleration channel may be configured to receive a pressurized fluid for accelerating the piston in a first direction. The hydraulic hammer may further have a first valve in communication with the acceleration channel. The first valve may be configured to selectively supply a first portion of the pressurized fluid to the acceleration channel. The hydraulic hammer may also have a second valve in communication with the acceleration channel. The second valve may be configured to selectively supply a second portion of the pressurized fluid to the acceleration channel. 本发明涉及具有双阀加速控制系统的液压锤。液压锤可具有壳体和配置成在该壳体内往复运动的活塞。液压锤还可具有形成于所述壳体内的加速通道。该加速通道可配置成接收用于使活塞在第方向上加速的加压流体。液压锤还可具有与所述加速通道连通的第阀。该第阀可配置成将所述加压流体的第部分选择性地供应至所述加速通道。液压锤还可具有与所述加速通道连通的第二阀。该第
