    • A variable displacement type compressor in which a discharge-pressure region, a suction-pressure region and a pressure control chamber are defined, has a tiltable swash plate and a piston reciprocated by the swash plate in the pressure control chamber. The inclination angle of the swash plate and the piston stroke are changed by adjustment of pressure in the pressure control chamber thereby to control the displacement of the compressor. The compressor further comprises a supply passage for supplying refrigerant gas from the discharge-pressure region to the pressure control chamber, a release passage for releasing the refrigerant gas from the pressure control chamber to the suction-pressure region, a first control valve for adjusting a cross-sectional area of the supply passage from the discharge-pressure region to the pressure control chamber and a second control valve for adjusting cross-sectional area of the release passage. The second control valve includes a valve body for opening and closing the release passage whose cross-sectional area is set minimum when the valve body is located at the closed position and a valve spring for urging the valve body in a direction to open the release passage. When the second control valve is closed, pressure in the supply passage downstream the first control valve acts on the valve body in a direction to close the release passage and pressure in the suction-pressure region acts on the valve body in a direction to open the release passage.

    • A displacement control valve of a clutchless variable displacement inclined plate-type compressor for controlling the discharge displacement of the compressor by opening and closing a communication path between a discharge chamber and a crank chamber. The displacement control valve has a valve hole (106) formed in the communication path and always communicating with the discharge chamber, an inside control valve (100) for opening and closing the valve hole (106) by a valve body (112) operated in response to expansion and contraction of a pressure sensing member (109) for sensing a suction pressure, and an operation switching device (120) connected to the inside control valve for switching the inside control valve between an operating condition where the valve body opens and closes the valve hole in response to the expansion and contraction of the pressure sensing member and a non-operating condition where the valve body opens the valve hole independently of the expansion and contraction of the pressure sensing member. In this displacement control valve, because a discharge pressure Pd acts on both the valve body (112) and a pressure sensing rod (110), the force of the discharge pressure Pd for urging the valve body (112) in a valve opening direction is (Sr−Sv)Pd. The displacement control valve can be made smaller than conventional displacement control valves because (Sr−Sv) is very small.
    • 一种用于通过打开和关闭排出室和曲柄室之间的连通路径来控制压缩机的排出位移的无离合器可变排量倾斜板式压缩机的排量控制阀。 排量控制阀具有形成在连通路径中并始终与排出室连通的阀孔(106),用于通过阀体(112)打开和关闭阀孔(106)的内侧控制阀(100) 响应于用于感测吸入压力的压力感测构件(109)的膨胀和收缩;以及操作切换装置(120),其连接到内部控制阀,用于在阀体打开和关闭的操作条件之间切换内部控制阀 响应于压力感测构件的膨胀和收缩的阀孔以及阀体独立于压力感测构件的膨胀和收缩而打开阀孔的非操作状态。 在该排量控制阀中,由于排出压力Pd作用在阀体(112)和压力传感杆(110)两者上,所以用于在阀打开方向上推压阀体(112)的排出压力Pd的力为 (Sr-Sv)Pd。 由于(Sr-Sv)非常小,因此位移控制阀可以比传统的位移控制阀小。

    • To provide a control valve for a variable displacement compressor, which is capable of stably operating in a pressure control area, and causing the compressor to quickly shift to operation with the minimum displacement. The control valve for a variable displacement compressor is capable of realizing stable pressure control, since a force applied to a valve element in a valve-closing direction increases when the valve element is in a pressure control area, and is balanced with a force applied to the valve element in a valve-opening direction by the pressure of refrigerant. Further, when the valve element moves past an end point of the pressure control area, the force applied to the valve element in the valve-closing direction decreases to thereby increase the valve-opening degree of a valve portion when the valve portion is fully open. Therefore, when a solenoid is not energized, it is possible to ensure a sufficient flow rate of refrigerant, thereby making it possible to cause the compressor to quickly shift to operation with the minimum displacement.
    • 提供一种可变排量压缩机的控制阀,其能够在压力控制区域中稳定地操作,并使压缩机以最小排量快速转换到操作。 用于可变排量压缩机的控制阀能够实现稳定的压力控制,因为当阀元件处于压力控制区域中时,在阀关闭方向上施加到阀元件的力增加,并且与施加到 通过制冷剂的压力使阀元件处于阀打开方向。 此外,当阀元件移动超过压力控制区域的终点时,在阀门关闭方向施加到阀元件的力减小,从而当阀部分完全打开时增加阀部分的开阀度 。 因此,当螺线管未通电时,可以确保制冷剂的足够的流量,从而可以使压缩机以最小的位移快速地转换到操作。

    • To provide a control valve for a variable displacement compressor, which can be realized with a simple construction, while being equipped with the function of a check valve to be disposed at an outlet port of the compressor. The control valve for a variable displacement compressor includes a main valve that sets a cross-sectional area-fixed passage in which the passage cross-sectional area thereof is substantially constant when refrigerant flows between a discharge chamber and an outlet port of the compressor, and closes the cross-sectional area-fixed passage due to inversion of the magnitudes of pressure across the cross-sectional area-fixed passage when the compressor is not in operation, a pilot valve that controls the flow rate of refrigerant flowing from the discharge chamber to a crankcase in a manner interlocked with the differential pressure across the cross-sectional area-fixed passage received by the main valve, and a solenoid that is capable of setting a valve lift of the pilot valve by an external signal. The pilot valve controls the flow rate of refrigerant allowed to flow into the crankcase so as to make constant the differential pressure across the cross-sectional area-fixed passage, to thereby provide control such that the flow rate of refrigerant allowed to flow to the outlet port of the compressor is constant.
