従い圧縮空間１３の圧力が上昇する。The rotational movement of the shaft 11 accompanying the rotation of the electric motor section 2 is transmitted to the orbiting scroll 5 via the boss section 11a and the projection section 10, but due to the action of the rotation prevention mechanism 6, the orbiting scroll 6 does not rotate on its own axis. The fixed scroll 4 rotates around the involute center as the rotation center. At this time,
Suction is complete when the winding end sb' of the wrap 5b of the orbiting scroll 6 is in contact with the wrap 4b of the fixed scroll 4, and the winding end 4b' of the wrap 4b of the fixed scroll 4 is in contact with the wrap 6b of the orbiting scroll 5. As the orbiting scroll 5 rotates, the wrap 4b and the wrap 6b
As the two contact points approach the center of the involute, the pressure in the compression space 13 increases.

冷却システム（図示せず）に吐出される。In the compression mechanism of this scroll compressor, the pressure in the suction chamber 9a becomes lower than the pressure in the suction pipe 16, and the spring force of the spring 17b pushing up the valve 17a increases as well as the force due to the differential pressure. When the upper valve mechanism 17 is in an open state, refrigerant is sucked from the suction pipe 16 through the suction hole 9° and the suction chamber 9a. The sucked refrigerant is compressed and discharged into the -H sealed casing 1 through the discharge hole 8, and then discharged through the discharge pipe 16 to a cooling system (not shown).

同圧となる為逆転が止まる（例えば特開昭６９−１１０
８８４号にて示される）。Also, when the compressor is stopped, the orbiting scroll 5 is reversed,
Since the high-pressure gas inside the sealed casing 1 flows backward, the inside of the suction chamber 9a becomes high pressure.
Due to the spring force, the suction pipe 16 is pushed up as shown by the broken line in FIG. 9 and sealed by contacting the end of the suction pipe 16, preventing backflow, and as a result, the suction chamber 9a and the inside of the sealed casing 1 are at the same pressure. Therefore, the reversal stops (for example, JP-A-69-110
No. 884).

わり部に引掛シ、動作が不確実になる問題があった。Problems to be Solved by the Invention In this conventional method, the effective cross-sectional area at the intersection of the suction hole and the suction chamber is calculated as: length of intersection x opening height M)
It is expressed as When designing a large compressor or a compressor with a small cylinder volume but rotating at high speed, in order to increase the effective cross-sectional area in order to minimize the pressure loss during suction, increasing the intersection length I-) will cause the suction hole to increase. If the diameter of the check valve mechanism is approximately equal to the width of the end of the winding, there is a problem in that the valve of the check valve mechanism gets caught in the intersection, resulting in uncertain operation.

くなる問題があった。There is also a method of making a deeper cut (18 in Figure 9) at the end of the winding in order to increase the opening height (M).
In this case, there is a problem that the lift of the valve of the reverse valve mechanism becomes large, and as a result, the height of the fixed scroll becomes high in order to secure this lift.

The present invention solves the problems of the conventional example described above, and reduces the pressure loss in the suction hole without increasing the size of the compressor, and also ensures the operability of the check valve mechanism.

きる。Operation The present invention has the above-described configuration, and during operation, the on-off valve is opened by the inflow of suction refrigerant, and when the operation is stopped, high-pressure refrigerant flows from the compression chamber to the suction chamber and flows out to the suction hole. Therefore, the on-off valve closes. Therefore, compared to conventional check valve structures, the lift of the check valve can be compensated for in the circumferential direction.

端部４ｃの第１吸入室２１ａを連通している。EXAMPLE An example of the present invention will be described below with reference to FIGS. 1, 2, and 3. Incidentally, the same parts as in the conventional example are given the same reference numerals, and the description thereof will be omitted. A sealing element 19 is provided at the end 4c of the fixed scroll, contacts and seals both wall surfaces and the bottom of the groove of the end 4C of the winding, and the mirror plate surface of the orbiting scroll, and has an opening 19a in the center. Reference numeral 20 denotes an on-off valve, which is rotatably attached to the sealing element 19 on one wall side of the groove, and connects the suction chamber 9a to the first suction chamber 21a and the second suction chamber 21b.
It is divided into 22 is a suction pipe provided in the radial direction;
Reference numeral 23 denotes a suction hole, and the suction hole 23 communicates the suction pipe 21 with the first suction chamber 21a of the winding end portion 4c.

9a opens. In this state, the suction refrigerant flows through the suction pipe 22. Suction hole 23. It is inhaled through the first suction chamber 21a and the second suction chamber 21b.

作動性を示す。Also, when the compressor is stopped, the second suction chamber 21
When the pressure inside b is high, some of the refrigerant enters the first suction gap, which causes resistance and causes the opening/closing valve 2
o closes the opening 19a and the compressor stops rotating in reverse. Therefore, in the conventional check valve structure, regardless of whether the suction pipe is installed in the axial direction or the radial direction, it is necessary to take the check valve height in the height direction and the radial direction, respectively.However, in the present invention, The on-off valve 20 moves in the circumferential direction, so that its height and radial dimensions can be reduced. Further, conventionally, it was necessary to press a spring on the back of the check valve when refrigerant was sucked, but the present invention does not require a spring, and therefore suction loss can be reduced. In addition, there is no problem such as the reverse valve becoming stuck as in the conventional case, and it exhibits good operability.
