The invention relates to the field of power machine building and may be used in mixing devices of gas generators for driving gas turbines, in particular, for liquid-propellant rocket engines.A gas generator comprises a cover with a hole, a bottom with a mixing chamber, a housing with an axial duct communicating with the hole in the cover. The housing is fastened in the cover hole and/or in the mixing chamber of the bottom. Grooves are made uniformly along the circumference of the cross section of the housing in the bottom and/or on the housing. The hole in the cover and the axial duct are designed to supply propellant, and the space between the cover and the bottom and the grooves in the bottom and/or on the housing are designed to supply an oxidizer. A propellant space is made in the cover, and the axial duct communicates through the propellant space with the hole in the cover by means of tangential propellant supply holes. An annular oxidizer duct and a cylindrical mixing chamber are additionally made in the module housing. The annular oxidizer duct is placed concentrically to the axial duct and communicates coaxially with the cylindrical mixing chamber, and by tangential oxidizer supply holes communicates with the space between the cover and the bottom.
