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: An electric compressor includes a casing; a compression mechanism for compressing a refrigerant inside the casing; a motor for providing power to the compression mechanism; and an inverter for controlling the motor, and the casing includes an inverter cover for sealing the inverter from an outside, the inverter cover includes a plate-shaped plate, and the plate includes a first plate portion and a second plate portion extending from the first plate portion and protruding toward an inside in which the inverter is embedded. Accordingly, it is possible to achieve increased rigidity of the inverter cover, reduced vibration and noise, and suppressed weight increase at the same time.
