Abstract: A scroll compressor of the present disclosure 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 housing includes a center housing through which the rotating shaft passes; a front housing forming a motor accommodating space in which the motor is accommodated; and a rear housing having a discharge chamber accommodating a refrigerant discharged from the compression chamber, a discharge port guiding the refrigerant of the discharge chamber to an outside of the housing, an introduction port into which an intermediate pressure refrigerant is introduced from the outside of the housing, and an introduction chamber accommodating the refrigerant introduced through the introduction port, and wherein the fixed scroll comprises an injection hole guiding the refrigerant of the introduction chamber to 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 valve assembly forms a check valve for a scroll compressor including a fixed scroll having a pair of injection ports fluidly coupled to a compression mechanism. The valve assembly includes a valve body having a pair of flow paths with each of the flow paths fluidly coupled to a corresponding one of the injection ports. An injection plate has a pair of injection holes. A reed structure is disposed between the injection plate and the valve body with the reed structure including a pair of reeds. Each of the reeds is configured to selectively provide fluid communication between a corresponding one of the injection holes and a corresponding one of the injection ports. A valve gasket is disposed between the reed structure and the valve body and includes a pair of flaps with each of the flaps configured to selectively contact a corresponding one of the reeds.

Abstract: A compressor that includes a casing, a compression mechanism provided inside the casing to compress a refrigerant, a rotary shaft transmitting a rotational force to the compression mechanism from a drive source provided outside the casing, a clutch connecting the drive source and the rotary shaft by a magnetic force generated when electric power is applied to the clutch and disconnecting the drive source and the rotary shaft by losing the magnetic force when the electric power applied thereto is cut off, and a rotation measurement means for receiving the magnetic force from the clutch to measure a change in magnetic flux according to the rotation of the rotary shaft and measure a rotational speed of the rotary shaft. Thus, it is possible to measure the rotational speed of the rotary shaft without including a permanent magnet.

Abstract: The present disclosure relates to a compressor including: a motor configured to generate a driving force; a compression mechanism configured to be 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 to each other; and a sealing member configured to seal a connection portion between a terminal of the motor electrically connected to the connector and the connector. Therefore, the refrigerant may be prevented from being introduced into the motor terminal and a short circuit may be prevented from occurring in the motor terminal.
