Abstract: A scroll compressor includes a housing; a motor provided in the housing; a rotating shaft rotated by the motor; an orbital scroll orbital moved by the rotating shaft; a fixed scroll forming a compression chamber together with the orbital scroll; an injection flow path guiding an intermediate pressure refrigerant from an outside of the housing to the compression chamber; and an injection valve assembly opening and closing the injection flow path, wherein the injection valve assembly includes a cover plate having an inlet through which the intermediate pressure refrigerant is introduced, an injection valve opening and closing the inlet, and a valve plate having an outlet guiding the refrigerant that has passed through the injection valve toward the compression chamber. Thereby, an amount of refrigerant discharged from the compression chamber is increased, and thus the performance and efficiency of the compressor may be improved.

Abstract: A scroll compressor includes a housing; a motor provided in the housing; a rotating shaft rotated by the motor; an orbital scroll orbital moved by the rotating shaft; and a fixed scroll forming a compression chamber together with the orbital scroll, wherein the fixed scroll includes an injection hole guiding an intermediate pressure refrigerant to the compression chamber, wherein the compression chamber is formed in a pair, and wherein the injection hole is formed to communicate with any one of the pair of compression chambers when communicating with the other one of the pair of compression chambers. Thereby, an amount of refrigerant discharged from the compression chamber is increased, and thus the performance and efficiency of the compressor may be improved.

Abstract: Disclosed herein is a compressor including a motor configured to generate a driving force, a compression mechanism driven by the motor to compress a refrigerant, an inverter configured to control the motor, a connector configured to electrically connect the motor and the inverter, and a sealing member configured to seal a motor terminal of the motor that is electrically connected to the connector. Accordingly, it is possible to prevent an electric leakage from occurring in the terminal of the motor by blocking introduction of a refrigerant into the motor terminal. It is possible to prevent separation of the connector and the coil from the motor terminal.

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.
