Variable capacity vane compressor. |
摘要 |
<p>A variable capacity vane compressor (l) has a pressure chamber formed in one side blocks (9) of a cylinder (2) and communicating a zone under lower pressure with a zone under higher pressure, and at least one second inlet port (23) the opening angle of which is variable in response to a difference between pressure within a first pressure chamber (271) of the pressure chamber and pressure within a second pressure chamber of same. The second pressure is communicated with the zone under higher pressure via a high-pressure communication passage and with the zone under lower pressure via a low-pressure communication passage. A control valve device (33) extends across the high-pressure communication passage (29) and the low-pressure communication passage (28), and is disposed to close the low-pressure communication passage (28) and simultaneously open the high-pressure communication passage (29) when pressure within the zone under lower pressure exceeds a predetermined value, and to open the low-pressure communication passage (28) and simultaneously effect one of closing and reduction of the opening area of the high-pressure communication passage (29) when the pressure within the zone under lower pressure is below the predetermined value, whereby the capacity of the compressor can be varied with high responsiveness.</p> |
