    Abstract: A pneumatic impact device and method provide a high powered striking force against a target object. The device includes a core shell that houses a piston sub-assembly and a sear arm sub-assembly, and that further defines a forward gas chamber and a rearward gas chamber. The rearward gas chamber is loaded with compressed fluid via a handle actuator. A mostly external sear trigger assembly responds to the impact of a striker plate against the target object, thereby releasing a sear arm that then releases a piston, which is then accelerated forward by the compressed fluid charge. The device can be re-set manually via compressed fluid (e.g., air) in one embodiment, or automatically via a spring mechanism in another embodiment.

    Abstract: A percussive tool comprises a percussion mechanism and a pressure pulser. The percussion mechanism has a hollow housing with a piston hammer arranged thereinside to form two chambers of variable volume. The pressure pulser has a hollow housing and a fluid displacer defining inside the housing a working chamber adapted to alternately communicate with a source of gaseous fluid and the interior of the percussion mechanism. The fluid displacer is intended for forced displacement inside the housing to transmit to the chambers of the percussion mechanism a pulsed pressure of the gaseous fluid which causes the piston hammer to reciprocate. The interior of the percussion mechanism is isolated from the outside, whereas the working chamber of the pressure pulser communicates with at least one of the chambers of the percussion mechanism, the chambers of the percussion mechanism continuously intercommunicating by way of a restrictor passage.

    Abstract: A hydraulic impact tool providing improved force absorption for facilitated manipulation by an operator. In the illustrated embodiment, the tool comprises a tamper which provides substantial tamping force with minimum vibration and uncontrolled bounce. The tool utilizes a hydraulic power system for improved noise reduction and minimizaton of fatigue. The tool provides a forward stroke wherein the force is applied for a preselected time, and a retraction stroke wherein the moving elements are retracted to a preselected position. The tool is adapted for use with a wide range of load resistances.

    Abstract: An hydraulic tool for mining and construction work designed to effect hydraulic reciprocating action of a piston to which a work implement is attached. The tool is illustrated as a rock drill. The tool avoids the usual impacting action and accompanying noise of a reciprocating piston hammer against a work implement. A motor operating independently of the reciprocating piston functions to rotate the piston and the work implement attached to the latter while the piston is reciprocating. A bulk oil accumulator forms part of the housing of the tool in which the piston reciprocates; and a power driven control valve determines the frequency of reciprocation and speed of the piston.

    Abstract: A hydraulic hammer for driving a demolition tool is disclosed. The hammer carries a piston which reciprocates in a cylinder. High pressure fluid drives the hammer to a retracted position to compress an air spring. The piston is momentarily held in the retracted position while an annular valve sleeve disposed about the piston is automatically moved downwardly by differential fluid pressure to open an annular passageway around the piston to permit the fluid to freely bypass the piston. The piston is then released so that the stored energy rapidly accelerates the hammer through an impact stroke without significant impedance from fluid and without displacing fluid from the cylinder. Since high pressure fluid is required only on the retraction stroke, the volume of fluid necessary to operate the hammer is essentially reduced by 50 percent, thus permitting either the force or frequency to be doubled for a given high pressure fluid source. A safety shuttle valve is also included which is cooperable with the tool member to bypass pressure fluid to reservoir until a predetermined load is imposed on the tool.

    Abstract translation: 公开了一种用于驱动拆除工具的液压锤。 锤子带有在气缸中往复运动的活塞。 高压流体将锤子驱动到缩回位置以压缩空气弹簧。 活塞瞬间保持在缩回位置,而围绕活塞设置的环形阀套通过差动流体压力自动向下移动,以打开围绕活塞的环形通道,以允许流体自由地绕过活塞。 然后释放活塞,使得存储的能量通过冲击行程快速加速锤,而没有来自流体的显着阻抗,并且不使液体从气缸移位。 由于仅在回缩行程中需要高压流体,所以操作锤子所需的流体体积基本上减少了50%,从而允许给定的高压流体源的力或频率加倍。 还包括安全梭阀,其与工具构件配合以将压力流体旁路到储存器,直到预定的负载施加到工具上。
