ABSTRACT:
A high-performance scroll compressor permits the prevention of the deformation of an end plate of a fixed scroll in a hermetically sealed vessel of a typical wall thickness and strength, thus obviating the need for increasing the wall thickness of the vessel or employing a material of higher strength to enhance the pressure resistance of the vessel. A partition is provided between the rear surface of the fixed scroll and the hermetically sealed vessel, and a hole of the partition is communicated with a discharge hole in the end plate of the fixed scroll. A covering member is mounted on the partition to form a muffler, and a discharge pipe is attached to the muffler.
