Abstract
A compressor includes a shell assembly, a compression mechanism and a suction fitting. The shell assembly defines a chamber. The compression mechanism is disposed within the chamber of the shell assembly and includes a suction inlet. The suction fitting is attached to the shell assembly and extends at least partially into the chamber of the shell assembly. The suction fitting defines first and second openings. The suction fitting directs working fluid through the first opening towards the compression mechanism and the suction fitting directs working fluid through the second opening away from the compression mechanism.
Claims19
A compressor comprising:
- a shell assembly defining a chamber and a shell opening;
- a compression mechanism disposed within the chamber of the shell assembly;
- and
- a suction fitting attached to the shell assembly and extending through the shell opening, the suction fitting including a portion extending into the chamber of the shell assembly, the portion of the suction fitting defining first and second openings,
- wherein the suction fitting directs working fluid through the first opening towards the compression mechanism and the suction fitting directs working fluid through the second opening away from the compression mechanism,
- wherein the portion of the suction fitting is sized and shaped such that the portion of the suction fitting can be inserted through the shell opening with the portion attached to the rest of the suction fitting,
- wherein the portion of the suction fitting has an axial end wall that defines the first opening at an axial end of the suction fitting,
- wherein the axial end wall extends radially inward relative to an inner diametrical surface of the portion of the suction fitting,
- wherein the first and second openings extend through the inner diametrical surface,
- wherein the inner diametrical surface is a cylindrical surface defined by a longitudinal axis that extends through the shell opening and through the axial end wall;
- and
- wherein the first opening has a larger area than the second opening such that a greater volume of working fluid flowing through the suction fitting flows out of the first opening than the second opening.
A compressor comprising:
- a shell assembly defining a chamber;
- a compression mechanism disposed within the chamber of the shell assembly and including a suction inlet;
- a motor disposed within the chamber and driving the compression mechanism;
- and
- a suction fitting assembly including a suction fitting and a deflector, the suction fitting attached to the shell assembly and extending at least partially into the chamber, the deflector is attached to the suction fitting,
- wherein a first portion of working fluid exiting the suction fitting flows to the suction inlet of the compression mechanism and a second portion of working fluid exiting the suction fitting is directed toward the motor via the deflector,
- wherein the deflector includes a first body portion and a second body portion extending from the first body portion, and wherein the first body portion defines a channel that directs the second portion of working fluid flowing therethrough toward the motor,
- wherein the deflector includes a plurality of resiliently flexible members extending from the second body portion, and wherein the plurality of resiliently flexible members snap into engagement with the suction fitting, and
- wherein the deflector includes tabs that extends outwardly from ends of the first body portion, and wherein the tabs contact the shell assembly to bias the deflector against the suction fitting.
A compressor comprising:
- a shell assembly defining a chamber and a shell opening;
- a compression mechanism disposed within the chamber of the shell assembly;
- and
- a suction fitting attached to the shell assembly and extending through the shell opening, the suction fitting including a portion extending into the chamber of the shell assembly, the portion of the suction fitting defining a first opening and including an axial end wall,
- wherein the suction fitting directs working fluid through the first opening towards the compression mechanism,
- wherein the portion of the suction fitting is sized and shaped such that the portion of the suction fitting can be inserted through the shell opening with the portion attached to the rest of the suction fitting,
- wherein the axial end wall defines an axial end of the suction fitting,
- wherein the axial end wall extends radially inward relative to an inner diametrical surface of the portion of the suction fitting, and
- wherein the first opening in the suction fitting extends through the axial end wall and through the inner diametrical surface,
- wherein the inner diametrical surface is a cylindrical surface defined by a longitudinal axis that extends through the shell opening and through the axial end wall,
- wherein the portion of the suction fitting defines a second opening, and
- wherein the second opening is an elongated slot, and wherein the first and second openings extend radially through the inner diametrical surface of the suction fitting and an outer diametrical surface of the suction fitting.
