| 摘要 |
The invention relates to a compressor comprising a rotatable portion where the active volume is divided by transverse wings (4a-b) and a rotatable ring element (2) with its normal at an angle to the rotation axis of the transverse wings. In any of their embodiments the sealing wings are attached to sealing holder taps (16bd1-2, 16ac1-2) that pass through driving slits (11a1 -2, 11b1-2). The driving slits extend essentially parallel to the rotation axis of the transverse wings. Steering and driving the sealing wings in this fashion using the driving slits, aligns the sealing wings against the transverse wings, restricting wear of the sealing wings and decreasing friction. In one embodiment the sealing holder taps are provided with sliders (17, 17a1-2, 17b1-2, 17c1-2, 17c1-2), guiding and further reducing wear of the sealing wings and decreasing friction, by means of guides (22a-d). The invention further relates to such a compressor with the means (7, 18, 19) for arranging the ring element with its normal at a changeable angle to the main rotation axis thereby changing the compression ratio. |
