Scroll compressor having end plates of fixed and revolving scrolls thicker than heights of spiral protrusions of the scrolls

摘要

A scroll compressor with which there is no leakage of the working gas from the compression chamber is disclosed, in which deformation of each end plate of the fixed scroll and revolving scroll is prevented. The scroll compressor comprises a casing; a fixed scroll provided in the housing and comprising an end plate and a spiral protrusion built on one face of the end plate; and a revolving scroll provided in the casing and comprising an end plate and a spiral protrusion built on one face of the end plate, wherein the spiral protrusions of each scroll are engaged with each other so as to form a spiral compression chamber. In the structure, a working gas introduced in the casing is compressed in the compression chamber and then discharged according to the revolving operation of the revolving scroll; and given thickness T₁ of the end plate of the fixed scroll, thickness T₂ of the end plate of the revolving scroll, height H₁ of the spiral protrusion of the fixed scroll, and height H₂ of the spiral protrusion of the revolving scroll, the following condition is satisfied: T₁0.9H₁, and T₂0.9H₂.
