ム、（至）は第２のスプリングである。Conventional configuration and its problems Conventionally, in a heat pump type air conditioner trap in which a compressor, four-way valve, outdoor heat exchanger, expansion mechanism, indoor heat exchanger, etc. are connected in sequence, the discharge pressure decreases due to overload. When the pressure rises above a predetermined level, some of the refrigerant is condensed in an outdoor heat exchanger, and the condensed liquid refrigerant is flowed through the high-pressure pressure regulating valve to the suction pipe side to lower the temperature on the suction pipe side. However, overload countermeasures to lower the discharge temperature and discharge pressure have become exhausted.
As the high-pressure pressure regulating valve, one having a structure as shown in FIG. 1 has been used. In FIG. 1, (1) is the main body of the regulating valve, (2) is the first spring held between the regulating screw (3) and the piston (4) in the main body (1), and (5) is the first spring held between the regulating screw (3) and the piston (4) in the main body (1).

) is provided with a refrigerant inlet (7) and an outlet (8), and a communication port (9) that is opened and closed by a ball valve body is provided in the middle. (B) is a plunger that holds the ball valve body portion; (6) is a diaphragm that is provided between the main body (1) and the lower main body (6) and to which the plunger (B) is fixed; ) is the second spring.

と冷媒が流れ、吸入管側に向かうのである。In such a configuration, when the pressure from the inlet (7) becomes higher than the set pressure, the push-up blade becomes weaker than the pressing force of the first spring (2), and the diaphragm is reversed upward. The ball valve body is pushed upward together with the plunger (9) by the pressing force of the second spring αO,
The communication port (2) begins to fly, and the refrigerant flows from the inlet (7) to the outlet (8) and toward the suction pipe.

When the load condition is such that the pressure of
25) and flows in from the inlet (61), and the pressure pushes the valve body (40) against the spring (68). At this time, the pressure at the inlet (61) is
When the pressure in 2) is greater than the sum of the pressure due to the pressing force of the spring (38), the on-off valve (41) is opened and the refrigerant is discharged (35) through the flow passage (44).
, flows through the orifice (39) to the outlet (32) and into the suction chamber (c). Here, since the pressure regulating valve (22) starts to open due to the pressure difference between the inlet and outlet, if the pressure regulating valve is simply a pressure regulating valve in which the valve body (40) is urged toward the valve boat (65) by a spring ((68), Open/close valve (41) depending on differential pressure
is opened, and when the pressure difference between the inlet (31) side pressure and the outlet (62) side pressure becomes smaller due to the opening, the valve body (40) moves in the closing direction, and when it closes, the pressure difference increases again. It is easy to open again, resulting in a so-called hunting condition. In this regard, according to the above-mentioned construction acid, an oriswiss (39) and a needle valve (42) integrated with a valve body (40) are provided on the outlet (32) side, and the valve body (40) is moved to the open position. Then, the needle valve (42) enters the orifice (69) to reduce the refrigerant flow area and restrict the refrigerant flow rate, so there is no fluctuation in pressure difference and no hunting phenomenon occurs. be. In addition, the flow rate is controlled by a needle valve (42
) so that the stopper (45
) is provided. Note that when used in such a refrigerant circuit, liquid refrigerant passes through this high-pressure pressure regulating valve (2) even when the load is large and the refrigerant reaches its maximum flow rate, so the valve body ( Even if the operating range of 41) is short, a sufficient refrigerant flow rate can be obtained.
