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.

Abstract: A high-performance compressor is capable of preventing inadequate oil feed even if the compressor tilts or foams and it is also capable of reducing the amount of oil discharged. The compressor has a compression element and an electric element housed in a hermetically sealed vessel, the interior of the hermetically sealed vessel being divided into an oil reservoir chamber and a hermetically sealed chamber. Two oil pumps are mounted on one end of a rotary shaft and oil is sucked into one of the oil pumps from the oil reservoir chamber and fed to the compression element mounted on the other end of the rotary shaft; oil is sucked into the other oil pump from the hermetically sealed chamber and fed to the oil reservoir chamber.
