摘要： A refrigerating cycle with a by-pass duct 5 in which heat exchange for heating is arranged to be performed in an evaporator 4 without passing refrigerant through a condenser 2 is designed to perform an auxiliary heating mode suitable for the instantaneous conditions by controlling the amount of refrigerant circulating in response to the load and the like. A by-pass duct 5 for supplying the refrigerant from the compressor 1 to the evaporator 4 without passing it through the condenser 2 is placed in juxtaposition. Between the outlet of the evaporator 4 and the inlet of the compressor 1 an accumulator 6 for temporarily storing low-pressure refrigerant liquid is provided so that the amount of refrigerant circulating is controlled by accumulator 6 while the refrigerant circulates via by-pass duct 5 without passage through condenser 2.

摘要： In a four-way directional control valve of simplified construction and reduced manufacturing costs, first and second hollow cylindrical valve elements are arranged coaxially. Adjacent to opposite ends of the valve elements, first and second valve seats and first and second valve closure elements are provided. First and second pressure-regulating chambers are arranged between separator walls of the valve elements and first and second partition walls associated to the first and second valve seats. A pilot valve can be switched between switching positions for introducing high-pressure fluid originating from a first pipe into the first or second pressure-regulating chamber via a common high-pressure passage, a high pressure introducing hole and two pilot holes, respectively, associated to the pressure-regulating chambers. The control valve can be switched into a state where the first pipe communicates with the fourth and the second pipe communicates with the third pipe and to another state where the first pipe communicates with the third pipe and the second pipe communicates with the fourth pipe.

摘要： In an expansion valve for controlling the flow rate of a refrigerant supplied to an evaporator of a refrigerating system, a temperature-sensing chamber is provided to sense the temperature of the refrigerant returning from said evaporator and to actuate a valve mechanism in order to regulate the flow of refrigerant supplied to said evaporator. An adsorption means provided inside the temperature-sensing chamber to adsorb a liquefied part of a gas charge within said chamber in order to hold said liquefied part away from warm wall parts inside said chamber. In addition, or as an alternative, said temperature-sensing chamber is separated from a return passage of said refrigerant by thermal-transfer-delay means for delaying the thermal transfer of a temperature change from the refrigerant to a sealed charge within said temperature-sensing chamber. Said thermal-transfer-delay means can be made as a flow restrictor for supressing an excessive flow between said chamber and said return passage of the refrigerant.

摘要： 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.
摘要翻译：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，在阀门关闭方向上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阀开度。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。

摘要： To provide a control valve which is capable of maintaining the minimum operation of a variable displacement compressor, by causing a valve section thereof to be fully opened, irrespective of the expanded or compressed state of a bellows, even when the suction pressure of the compressor is high. In the control valve for a variable displacement compressor, a bellows is disposed between a pressure-sensing piston and a core in a pressure-sensing chamber, and a pressing force-transmitting member which is fixed to a plunger is interposed between the pressure-sensing piston and the bellows. Then, a spring which urges the pressing force-transmitting member toward a valve section is disposed between the pressing force-transmitting member and the bellows. As a result, even if the bellows contracts due to high suction pressure Ps, the pressing force-transmitting member is held in a state being urged toward the valve section by the spring, which causes a valve element to be pushed upward via the pressure-sensing piston, to make the valve section fully open, whereby the minimum operation of the compressor can be maintained.

摘要： To improve the manufacturing efficiency of a body, and reduce the manufacturing cost of an expansion valve. A body accommodating a valve section is formed, using forming dies, such as die-casting dies, integrally with an inlet port for introducing refrigerant, an outlet port for delivering expanded refrigerant, a male thread, and has a power element connected thereto by the male thread. This eliminates a necessity of subjecting the body to fabrication, for forming the inlet port, the outlet port, a valve hole, a hole for receiving therein a valve element and set value-adjusting members, a hole for receiving therein a shaft which transmits an actuating force dependent on temperature sensed by the power element to the valve element, and further the male screw. Therefore, the manufacturing efficiency of the body is improved, and the manufacturing cost of the expansion valve can be reduced.

摘要： To provide a fluid control valve which is capable of preventing or suppressing degradation of the accuracy of flow rate control dependent on the lift amount of a valve element from a valve seat. An expansion valve is configured such that a valve portion and a valve portion integrally formed with a valve element move to and away from a valve seat and a valve seat, respectively, simultaneously. Further, the expansion valve is configured such that a flow passage cross-section formed by a gap between the valve portion and the valve seat, and a flow passage cross-section formed by a gap between the valve portion and the valve seat have approximately the same size when the expansion valve is open. As a result, it is possible to almost cancel the influence of changes in effective pressure-receiving areas acting on the respective valve elements when the expansion valve is open, on the pressure balance, thereby making it possible to prevent degradation of the accuracy of flow rate control dependent on the lift amount of the valve elements.

摘要： To reduce the degree of influence of differential pressure on a pilot valve of a constant flow rate expansion valve. The constant flow rate expansion valve comprises a restriction passage for restricting the flow rate of refrigerant introduced from a refrigerant inlet port, a main valve for controlling the flow rate of refrigerant having flowed out from the restriction passage for discharging the refrigerant to a refrigerant outlet port, a piston for actuating the main valve in the valve-opening/closing direction by the differential pressure between intermediate pressure on the inlet port side of the main valve and pressure in a pressure chamber formed on the opposite side of the main valve, and a pilot valve for sensing the differential pressure proportional to the flow rate of refrigerant flowing through the restriction passage, thereby controlling the pressure in the pressure chamber set by a solenoid. In parallel with the main valve are arranged the pilot valve, the pressure chamber, and a fixed orifice in series in the direction of flow of refrigerant. This makes it possible to apply only the same level of differential pressure as that of small differential pressure applied to opposite end faces of the piston to the pilot valve, thereby making it possible to lessen the degree of influence of differential pressure on the pilot valve.

摘要： A constant flow rate expansion valve includes a refrigerant passage having a fixed flow path cross-sectional area smaller than that of a refrigerant inlet, a differential pressure control valve for controlling the differential pressure (P1−P2) between an inlet pressure P1 and an intermediate pressure P2 generated by refrigerant flowing through the refrigerant passage to be constant, and a solenoid capable of setting the differential pressure by the value of an electric current externally supplied. In the differential pressure control valve, a piston and a valve element integrally formed with each other sense the differential pressure (P1−P2), change a gap between the valve element and a valve seat such that the differential pressure is held constant, and adiabatically expand the refrigerant at the gap.
