Abstract
An exemplary embodiment of the jet hammer includes an outer sleeve, impact assembly, and a valve assembly. The impact assembly is positioned in sliding relation to the outer sleeve to provide the impact of the jet hammer. The valve assembly generally comprises a cap screw, adjustment sleeve, valve port, inner compression spring, outer compression spring, and lock nut. The inner compression spring is relatively less compressible than the outer compression spring. In operation, fluid enters the valve assembly and acts on the compression springs forming an operational seal between the valve assembly and the impact assembly thereby slidingly displacing the outer sleeve from the impact assembly. Once the pressure acting on the valve assembly is released, the main compression spring decompresses forcefully causing an impact which is translated onto the obstruction or item to be struck.
