An injector for introduction of fluids into soil, solid and fractional building materials, wood and similar materials comprises a body, a part for connection with a solution feed device, a part which is installed at least into the soil, a longitudinal opening in the body for solution flow and a check valve. Part of the body for installation of a solid tube mounted in a hole in ground or in solid building material, or fractional construction material or wood or a similar material, or for direct installation in a hole in ground or building material, which does not crumble or collapse, has an external tapered surface with decreasing diameter with a thread intended for screwing into the seal, the check valve with a ball and a stopper in the longitudinal opening, which has a variable diameter, the first diameter which is closer to the part of the body is intended for connection to solution feed device and is less than the ball diameter, the second diameter equals to or exceeds the ball diameter for not more than 0.5 mm, preferably 0.1 mm, and a third diameter is larger than the ball diameter for 0.5-1.5 mm, preferably 1.0 mm. |
