Title: Innovations by Lars Johansson in Rotary Screw Compressors

Introduction

Lars Johansson is a notable inventor based in Stavsnas, Sweden. He has made significant contributions to the field of rotary screw compressors, particularly with his innovative designs aimed at improving efficiency and reducing gas leakage.

Latest Patents

Johansson holds a patent for a "Shaft seal and bearing members for a rotary screw compressor." This invention involves a screw rotor machine that features a pair of intermeshing rotors with helical lands and intervening grooves. The design includes a casing with a working space comprised of two intersecting bores, each enclosing one of the rotors. Each rotor has a cylindrical projection that passes through a hole in an end wall at the high-pressure end of the machine into a bearing chamber. To prevent gas leakage from the working space to the bearing chamber, an annular element surrounds each rotor projection and is non-rotatably fixed to the casing. This innovative sealing mechanism allows for effective sealing even when the axis of the hole and that of the rotor projection are non-aligned.
