摘要： A hollow housing has a piston hammer arranged for reciprocation therein. hammer has a rear end chamber, an air distributing valve secured in the rear end portion of the housing and adapted to be received by the rear end chamber of the piston hammer. A headpiece is secured to the forward end portion of the housing and subjected to impact of the piston hammer. A retainer embraces by at least one of its ends, the forward end portion of the housing and is disposed coaxially relative to the housing and the headpiece to ensure clamping of the forward end portion of the housing between the retainer and the headpiece.

摘要： An air-operated reversible percussive action machine comprises a housing in which there is disposed for axial reciprocations a hammer, defining therewith a front working chamber and having a through radial passage. In the axial interior of the hammer on the side of its tail end there is provided a cylindrical stepped tube including coaxially arranged first and second steps of large and small diameters, respectively, these steps having through radial passages. The first step of the tube defines with the hammer a rear working chamber, and with the second step defines an annular cavity in which a spring sleeve capable of axial displacements is disposed. The outer diameter of the sleeve is substantially less than the inner diameter of the first step of the tube to form an annular passage there between. The machine is further provided with a means for pressure-sealing the annular cavity and a means for controlling the displacements of the sleeve.
摘要翻译：一种气动可逆式冲击作用机器包括壳体，其中设置有用于轴向往复运动的锤，其中限定有前工作室并且具有贯穿的径向通道。在其尾端侧面的锤的轴向内部分别设置有圆柱形阶梯管，分别包括大直径和小直径同轴布置的第一和第二台阶，这些台阶具有通过径向通道的台阶。管的第一步用锤子确定后工作室，并且第二步骤限定了环形空腔，其中布置有能够进行轴向位移的弹簧套筒。套管的外径基本上小于管的第一台阶的内径，以在其间形成环形通道。机器还设置有用于对环形腔进行压力密封的装置和用于控制套筒位移的装置。
