Abstract: The present disclosure relates to turbine comprising a housing having an input port and at least one output port. The turbine also comprises two rotors enclosed within the housing. The rotors counter-rotate within a same plane. In their rotation, the two rotors cooperate to create chambers within the housing. A chamber is created and starts to expand while another chamber having been created earlier continues its own expansion. One of these expanding chambers is connected to the input port. A third chamber is in contact with an output port. The turbine may be used as a compressor, an energy generator, a pump or as a building block of a motor.
