    摘要： A high-performance and high-reliability scroll compressor which prevents seal property failure at seal necessary points, tooth tip contact, abnormal wear of an elastic body, fatigue failure, etc. A radially outward peripheral projection (4c) is formed on the full outer peripheral surface of a separation plate (4). The peripheral projection (4c) is set to an outer diameter reduced, relative to the inner diameter of the shell main body (9) before a shell lid (20) is sealed by welding, etc., by the dimension corresponding to the shrinkage amount of a shell main body (9). That is, before welding, a minute gap occurs between the outer peripheral surface of the peripheral projections (4c) and the inner peripheral surface of the shell main body (9). Then, the separation plate (4) is inserted into the shell main body (9) and further the separation plate (4) and a frame (3) are fixed. After this, when the shell main body (9) and the shell lid (20) are welded, because of shrinkage of the shell main body (9) after the welding, the outer peripheral surface of the peripheral projections (4c) of the separation plate (4) comes in tight contact with the inner peripheral surface of the shell main body (9), whereby the space is partitioned and sealed between a high pressure space (30) and a low pressure space (31).

    摘要： The invention concerns a scroll compressor which is low in noise caused by water hammering of a refrigerant gas just after a discharge valve is closed. The scroll compressor includes a discharge member (45) having a discharge port (8) opposed to a discharge port (5) of a fixed scroll (2) and a discharge valve (9) opposed to the discharge port (8) of the discharge member (45) and opened/closed depending on a difference between flow passage pressure of a refrigerant gas and pressure in a high pressure space (27) in a sealed vessel (1). At least either of the fixed scroll (2) and the discharge member (45) is formed with a muffler chamber communicated with the discharge port (5, 8) and having a diameter larger than a diameter of the discharge port (5) of the fixed scroll (2) for suppressing occurrence of an impulse wave caused by water hammering when the discharge valve (9) is closed. Noise caused by a pressure ripple of the discharge port lessens, quieting the operation of the scroll compressor.

    摘要： A compressor includes a compression mechanism part for compressing refrigerant sucked from an outside of the hermetic container and discharging compressed refrigerant to a discharge space, an electric motor part composed of a stator and a rotor, facing a first space which is at an opposite side of the discharge space with respect to the compression mechanism part in the hermetic container, for driving the compression mechanism part through a main shaft, a passage at an external circumferential side of the compression mechanism part, for connecting the discharge space with the first space, and a fan provided at an end of the rotor, facing the first space. The refrigerant discharged into the discharge space passes through the passage at the external circumferential side of the compression mechanism part to reach the first space, and passes the fan to be discharged to the outside of the hermetic container.
