Abstract
A scroll compressor including a housing, a motor in the housing, an orbiting scroll, and a fixed scroll. An injection valve assembly is provided between the fixed scroll and the housing and further includes a cover plate, a valve plate, a gasket retainer, and an injection valve. The compressor capable of increasing a surface pressure at a position at which the injection valve of the injection valve assembly needs to be supported, and preventing deformation of the gasket retainer by reducing a bead height of the gasket retainer.
Claims14
A scroll compressor comprising:
- a housing;
- a motor provided in the housing;
- a rotary shaft configured to be rotated by the motor;
- an orbiting scroll configured to orbit in conjunction with the rotary shaft;
- and
- a fixed scroll configured to define a compression chamber together with the orbiting scroll, wherein the housing further comprises a rear housing configured to define a discharge chamber that accommodates a refrigerant discharged from the compression chamber, wherein an injection valve assembly is provided between the fixed scroll and the rear housing, defines, in the rear housing, an introduction chamber into which the refrigerant is introduced from outside of the housing, and guides the refrigerant in the introduction chamber to the compression chamber,
- wherein the injection valve assembly further comprises:
- a cover plate coupled to the rear housing and having an inlet port into which the refrigerant in the introduction chamber is introduced;
- a valve plate coupled to the cover plate and having an outlet port from which the refrigerant introduced through the inlet port is discharged;
- a gasket retainer interposed between the cover plate and the valve plate and configured to prevent a leak of the refrigerant;
- and
- an injection valve interposed between the cover plate and the gasket retainer and configured to open or close the inlet port, wherein the valve plate has a surface pressure enhancement portion protruding toward the injection valve.
A scroll compressor comprising:
- a housing;
- a motor provided in the housing;
- a rotary shaft configured to be rotated by the motor;
- an orbiting scroll configured to orbit in conjunction with the rotary shaft;
- and
- a fixed scroll configured to define a compression chamber together with the orbiting scroll, wherein the housing comprises a rear housing configured to define a discharge chamber that accommodates a refrigerant discharged from the compression chamber, wherein an injection valve assembly is provided between the fixed scroll and the rear housing, defines, in the rear housing, an introduction chamber into which the refrigerant is introduced from the outside of the housing, and guides the refrigerant in the introduction chamber to the compression chamber,
- wherein the injection valve assembly comprises:
- a cover plate coupled to the rear housing and having an inlet port into which the refrigerant in the introduction chamber is introduced;
- a valve plate coupled to the cover plate and having an outlet port from which the refrigerant introduced through the inlet port is discharged;
- a gasket retainer interposed between the cover plate and the valve plate and configured to prevent a leak of the refrigerant;
- and
- an injection valve interposed between the cover plate and the gasket retainer and configured to open or close the inlet port, wherein a stepped portion is formed around a surface of the valve plate that faces the gasket retainer.
