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. In response, the outer sleeve is slidingly displaced from the impact assembly thereby compressing a main compression spring positioned along the mandrel shaft. Once the pressure acting on the valve assembly is released, the main compression spring decompresses forcefully causing the outer sleeve to impact a connection port, bit, tool, or other member attached to the upper end of the mandrel.
