Abstract: A scroll compressor including a casing; an orbiting scroll orbitingly moved inside the casing; a fixed scroll engaged with the orbiting scroll to form a pair of compression chambers; and a main frame supporting the orbiting scroll, wherein the fixed scroll includes a fixed scroll base plate and a fixed scroll wrap protruding from the fixed scroll base plate, wherein the main frame includes a main frame base plate provided on an opposite side of the fixed scroll base plate with respect to the orbiting scroll, and wherein the fixed scroll base plate, the main frame base plate and the casing may form an orbiting space of the orbiting scroll. An orbiting radius of the orbiting scroll is increased inside the casing having a predetermined size, so a refrigerant discharge amount is increased in a state in which the orbiting scroll and the fixed scroll are accommodated inside the casing.

Abstract: A scroll compressor including a center housing; a front housing fastened to the center housing and forming a suction chamber; a rear housing fastened to the center housing and forming a compression mechanism accommodation space. Fixed scroll is in the compression mechanism accommodation space. An orbiting scroll interposes between the center housing and the fixed scroll forming a compression chamber together with the fixed scroll. Fixed scroll may include a fixed scroll end plate and a fixed scroll side plate protruded from outer circumferential portion of fixed scroll end plate, fastened to the center housing, and forming orbiting space of orbiting scroll. Outer circumferential portion of the center housing may be formed with an inflow hole for communicating with the suction chamber. Distal end surface of the fixed scroll side plate is formed with a suction port for guiding the refrigerant of the inflow hole to the compression chamber.
