本発明は空気や冷媒を吸入し圧縮する密閉型圧縮機の吸
入装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a suction device for a hermetic compressor that sucks in and compresses air or refrigerant.

成であった。第４図は吸入穴２囲シの斜視図である。Structure of conventional example and its problems Conventionally, this type of hermetic compressor has an electric element and a compression element driven by this electric element disposed in a hermetic container, and further has a structure as shown in Fig. 3. The structure was such that a suction hole 2 having the same cross-sectional shape was provided through a cylinder 1 constituting a compression element. FIG. 4 is a perspective view of the suction hole 2.

が減少するという問題があった。In such a configuration, when a part of the refrigerant is injected into the cylinder compression part 5 in a gas or liquid state through the injection injection opening hole 4 provided in the cylinder 1 or the bearing end plate 3, the injection injection occurs. Since the angle θ formed by the position of the opening hole 4 and the device □ at the outlet of the suction hole 2 is small, the refrigerant injected from the injection opening hole 4 passes through the outlet 2a of the suction hole 2 and flows back to the suction inlet 2b. However, there was a problem in that the refrigerant circulation was obstructed and the refrigerating capacity of the compressor was reduced.

側・出口部をスリット状の溝にしたものである。In order to achieve this objective, the present invention provides a suction hole in the cylinder constituting the compression element from the outside of the closed container toward the inner surface of the cylinder, and the outlet portion of the suction hole is connected to the inner surface of the cylinder. This is a slit-like groove.

。With this configuration, the relative angle between the position of the injection hole and the outlet of the suction hole can be made large, and the refrigerant injected from the injection opening hole does not flow back to the suction inlet through the suction hole outlet. Decrease in circulation volume can be prevented.

の摩耗に対して、好影響を及はす。With such a configuration, the injection opening 60 arranged on the bearing end plate 7 and the slit-shaped suction hole outlet 1
The angle with 0b is about 16 degrees larger than the conventional angle, and gaseous or liquid refrigerant is injected into the cylinder compression section 1.0 through the injection opening hole 9.
1, the refrigerant is less likely to flow back through the suction hole outlet 10b to the suction 6 inlet 10a, and by applying the injection, the refrigerating capacity of the compressor is less likely to decrease. Furthermore, as the pressure inside the cylinder increases, conventionally the suction hole portion of the vane groove 12 has suffered significant wear due to the frictional force generated on the contact surface between the vane 13 and the vane groove 12. By providing this, the portion surrounded by the vane groove 12 and the slit-shaped suction hole outlet 10b provides a cushioning effect, which has a favorable effect on wear of the suction hole portion of the vane groove 12.
