め、叩き現象による異音、弁割れ等の問題もあった。Conventional configurations and their problems Generally, rotary compressors do not have suction valves compared to reciprocating compressors, so they can achieve high volumetric efficiency, but on the other hand, they suffer from insufficient sealing of the discharge valves. When the compressor is stopped, the refrigerant flows from the high-pressure side to the low-pressure side until the pressure becomes equal -1-, and the oil is separated and stored in the compression chamber.When the compressor starts operating again, it enters a liquid compression state and the compression mechanism section There is a risk of destruction. For this reason, conventional methods have been taken such as installing a relief valve that operates when the pressure in the compression chamber rises above a set pressure, and improving the finish accuracy of the discharge port to an extremely high level. There was a problem of high costs due to increased man-hours. Furthermore, if foreign matter enters the contact area between the discharge valve and the discharge port during the cycle, in a vane type compressor, reverse rotation occurs and an unpleasant sound is produced. Furthermore, since the discharge valve and the discharge port are made of iron-based metal, there are problems such as abnormal noises caused by hammering and valve cracking.

In the figure, 1 is a cylinder of a rotary compressor, and a compression chamber 2 is formed inside the cylinder. A rotor 3 and vanes 4 are arranged in the compression chamber 2, and a suction port is provided on the side wall of the cylinder. A suction passage 6 communicating with the air intake passage 5 is formed. 7
is a discharge chamber formed in the upper part of the cylinder 1, and a discharge boat 8 is provided on the upper wall thereof. Reference numeral 9 denotes a discharge passage that communicates the compression chamber 2 and the discharge chamber 7, and is formed in the earthen wall of the cylinder 1. Reference numeral 10 denotes a discharge device according to the present invention provided at the outlet of the discharge passage 9, which will be described in detail below with reference to FIG. 2. In other words, the cylindrical member 12 having the through hole 11 may be simply press-fitted into the outlet of the discharge passage 3-3 (9), and the upper end surface of the cylindrical portion 11112 is An annular elastic body 14 having a discharge port 13 formed in the center is fixed thereto.

ことはない。Next, when the operation is stopped, the pressure in the discharge chamber γ causes the discharge valve 15 to press tightly against the annular elastic body 14, so that no backflow of refrigerant to the compression chamber 2 occurs. Further, even if a foreign object is caught between the discharge valve 15 and the annular elastic body 14, the annular elastic body 14 side will only be depressed and the sealing performance will not be affected.

である。Effects of the Invention According to the above configuration of the present invention, the discharge chamber and the compression chamber are isolated by the contact between the discharge valve and the annular elastic body, so that the tapping noise is quiet during operation, and when the operation is stopped, In this case, good sealing properties are obtained by taking advantage of the characteristics of the elastic body, which prevents the refrigerant from flowing back into the compression chamber and eliminates liquid compression during restart. Since the valve is shut off through the body, there is no need to improve the finishing accuracy of the contact surfaces between the discharge valve and the annular elastic body, leading to cost reduction.
Further, since the annular elastic body is attached to the outlet of the discharge passage through the cylindrical member, its attachment is extremely simple and easy.
