    • 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.
    • 叶片式压缩机设置有控制阀装置,该控制阀装置具有设置在低压区域内的可变形构件,用于响应于其中的压力而膨胀和收缩。 压力响应控制装置与用于控制压缩机的容量的控制阀装置相关联。 当低压区内的压力高于预定值时,可变形构件收缩并使控制装置使压缩机进入全容量操作,而可变形构件膨胀并使控制装置使压缩机部分 当低压区内的压力低于预定值时,容量操作。 提供一种可响应于可变形构件的过度膨胀而操作以使控制装置使压缩机进入全容量操作的装置。

    • A variable capacity vane compressor comprising a control element having at least one pressure-receiving protuberance dividing a space into a first and a second pressure chamber, wherein the control element angularly moves in response to a differential pressure between the first and second pressure chambers, to vary an opening angle of a second portion of at least one inlet port. The control element has mounted thereon a sealing member for sealing between the first and second pressure chambers and between a low pressure chamber and a vane back pressure zone. The sealing member comprises a first sealing portion for sealing between a peripheral wall surface of a central bore in the control element and an inner peripheral side wall surface of an annular recess in a side block, a second sealing portion for sealing between an outer peripheral surface of the control element and an outer peripheral side wall surface of the annular recess, a third sealing portion for sealing between an outer peripheral edge of the pressure-receiving protuberance and the wall surface of the space, and a fourth sealing portion for sealing between an axial end face of the control element and a bottom wall surface of the annular recess.

    • A variable capacity vane compressor has a pressure chamber formed in one of side blocks of a cylinder and communicating a zone under lower pressure with a zone under higher pressure, and at least one second inlet port the opening angle of which is variable in response to a difference between pressure within a first pressure chamber of the pressure chamber and pressure within a second pressure chamber of same. The second pressure chamber 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 extends across the high-pressure communication passage and the low-pressure communication passage, and is disposed to close the low-pressure communication passage and simultaneously open the high-pressure communication passage when pressure within the zone under lower pressure exceeds a predetermined value, and to open the low-pressure communication passage and simultaneously effect one of closing and reduction of the opening area of the high-pressure communication passage 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.
