Abstract
An injection gun includes a filler material injection assembly. The filler material injection assembly includes a pressure regulator handle to control a flow of filler material, a four-way valve, a pressure gauge, a pressure release valve assembly, and a first output coupling. The four-way valve is connected to the pressure regulator handle. A first port of the four-way valve is connected to the pressure regulator handle to receive the filler material under pressure. The pressure gauge is connected to a second port of the four-way valve to indicate a level of pressure of the filler material under pressure. A pressure release valve assembly is connected to a third port of the four-way valve. The pressure release valve assembly reduces the level of pressure of the filler material under pressure. A first output coupling is connected to a fourth port of the four-way valve to eject the filler material under pressure.
