SCROLL COMPRESSOR

摘要

A scroll compressor is provided that may include a casing; a discharge cover fixed to an inner space of the casing, that divides the inner space of the case into a suction space and a discharge space; a main frame in the casing, and spaced from the discharge cover; an orbital scroll that performs an orbital motion on the main frame; a non-orbital scroll coupled to the main frame so as to be movable up and down with respect to the orbital scroll, that forms a suction chamber, an intermediate pressure chamber, and a discharge chamber together with the orbital scroll; and a back pressure plate provided between the discharge cover and the non-orbital scroll, that forms a back pressure chamber that communicates with the intermediate pressure chamber. With such a configuration, a bypass valve may be easily installed, and application of an overload minimized.

1. A scroll compressor, comprising:
a casing; a discharge cover fixed to an inner space of the casing, that divides the inner space of the case into a suction space and a discharge space; a main frame arranged in the casing, and spaced from the discharge cover; an orbital scroll that performs an orbital motion in a state in which the orbital scroll is supported on the main frame; a non-orbital scroll coupled to the main frame so as to be movable in an upward and downward direction with respect to the orbital scroll, that forms a suction chamber, an intermediate pressure chamber, and a discharge chamber together with the orbital scroll; and a back pressure plate provided between the discharge cover and the non-orbital scroll, that forms a back pressure chamber that communicates with the intermediate pressure chamber, the back pressure plate having a discharge passage at a central portion thereof that communicates with the discharge space.
