  • Variable capacity vane compressor
    Patent number: 4850815
    Abstract: A vane compressor is provided with a control valve device having a deformable member disposed within a zone under low pressure for expansion and contraction in response to pressure therein. A pressure-responsive control device is associated with the control valve device for controlling the capacity of the compressor. The deformable member contracts and causes the control device to bring the compressor into full-capacity operation when the pressure within the zone under low pressure is higher than a predetermined value, whereas the deformable member expands and causes the control device to bring the compressor into partial-capacity operation when the pressure within the zone under low pressure is lower than the predetermined value. A device is provided which is operable in response to excessive expansion of the deformable member for causing the control device to bring the compressor into full-capacity operation.
