Abstract: An electric compressor including a motor configured to generate power; a compression mechanism configured to receive the power from the motor and compress a refrigerant; and an inverter configured to control the motor. A housing receiving the motor and the inverter includes a partition wall that divides a motor receiving space receiving the motor and an inverter receiving space receiving the inverter, and a suction port guiding the refrigerant to the motor receiving space. The partition wall includes a rib that protrudes from a surface facing the motor receiving space. As a result, it is possible to sufficiently cool a plurality of elements of an inverter as a whole and to suppress temperature deviation between the plurality of elements, thereby suppressing damage, operation stop, and increase in maintenance cost.

Abstract: A swash plate compressor including a cylinder block accommodating a piston for compressing a refrigerant, a front housing coupled to the front of the cylinder block and having a crank chamber, a rear housing having a suction chamber and a discharge chamber and coupled to the rear of the cylinder block. The swash plate compressor includes a valve assembly with a valve plate inserted into the rear housing, a gasket in the cylinder block, a suction plate between the valve plate and the cylinder block, a variable orifice module having a first orifice hole for refrigerant passing, a second orifice hole communicating with the suction chamber to discharge the refrigerant passing through the first orifice hole to the suction chamber, and an intermediate passage connecting the orifice holes, the first orifice hole having a variable reed, a degree of opening of which is varied depending on the refrigerant pressure.

Abstract: Disclosed is a suction damping case. A refrigerant introduced into the suction damping case flows for a predetermined period of time at reduced pressure and speed, and then is discharged to the outside of the body, so that a damping function can be made. When the suction damping case is coupled to a rear housing, a hook and an embossing prevents the suction damping case from being separated.
