Tocircle (private company)

Tocircle Industries has developed a mechanical rotating device that can be designed to work as a pump, a multiphase compressor, an expander or turbine, or even as a motor. Its operating principle is similar to a rotary vane machine in which the vane tip distance from the outer casing is minutely controlled by an internal mechanical arrangement. This feature makes it possible to scale up the machine to significantly larger dimensions than conventional rotary vane devices.
