Vapor injection structure for a compressor

A scroll compressor, comprising:

• a compression mechanism including a fixed scroll and an orbit scroll, wherein the fixed scroll includes a discharge port, a first injection port, and a second injection port formed therein;
• a first valve assembly coupled to the fixed scroll configured to selectively permit a flow of a fluid from the compression mechanism through the discharge port;
• and
• a second valve assembly coupled to the fixed scroll configured to selectively permit a flow of the fluid from an injection chamber through at least one of the first injection port and the second injection port, the valve assembly comprising:
• a reed structure having a first reed and a second reed, wherein the first reed is configured to be received in a first indentation of the fixed scroll of the compression mechanism and the second reed is configured to be received in a second indentation of the fixed scroll of the compression mechanism;
• a valve member disposed adjacent the reed structure, wherein the valve member includes a first injection aperture and a second injection aperture formed therethrough, and wherein the first injection aperture is in fluid communication with the first injection port of the compression mechanism and the second injection aperture is in fluid communication with the second injection port of the compression mechanism;
• and
• a valve gasket disposed adjacent the valve member, wherein the valve gasket includes a bead formed around a periphery thereof, and wherein the bead is configured to be compressed between the valve member and a housing portion of the scroll compressor;
• and
• an axially extending inner wall formed in a housing cavity, the bead engaging the inner wall peripherally, wherein the inner wall separates the injection chamber and a discharge chamber formed in the housing portion.

A scroll compressor, comprising:

• a compression mechanism including a fixed scroll and an orbit scroll, wherein the fixed scroll includes a discharge port and a recessed pocket having a first injection port and a second injection port formed therein;
• a first valve assembly coupled to the fixed scroll configured to selectively permit a flow of a fluid through the discharge port into a discharge chamber of the scroll compressor;
• and
• a second valve assembly coupled to the fixed scroll, the valve assembly comprising:
• a reed structure at least partially disposed in the recessed pocket of the fixed scroll;
• a valve member disposed adjacent the reed structure, wherein the valve member includes a first injection aperture and a second injection aperture formed therethrough, wherein the first injection aperture is in fluid communication with the first injection port of the fixed scroll and the second injection aperture is in fluid communication with the second injection port of the fixed scroll, and wherein the reed structure includes at least one reed configured to selectively permit a flow of the fluid through at least one of the first injection port and the second injection port of the fixed scroll into the compression mechanism of the scroll compressor;
• and
• a valve gasket disposed adjacent the valve member,
• a housing portion configured to receive at least a portion of the fixed scroll therein, wherein the valve gasket is configured to provide a substantially fluid-tight seal between the valve member and the housing portion of the scroll compressor, wherein the valve gasket includes a bead formed around a periphery thereof, and wherein the bead is configured to be compressed between the valve member and the housing portion of the scroll compressor;
• and
• an axially extending inner wall formed in a housing cavity, the bead engaging the inner wall peripherally, wherein the inner wall separates an injection chamber formed in the housing portion and the discharge chamber.
