Abstract

A refrigeration system includes a fluid circuit circulating a refrigerant in a closed loop. The fluid circuit has operably disposed therein, in serial order, a compressor, a first heat exchanger, an expansion device and a second heat exchanger. The compressor is pivotable about an axis. The compressor has a first part and a second part slidably coupled to the first part. A linkage includes a cyclically movable element. A linking element is attached to the second part of the compressor and is pivotably coupled to the cyclically movable element such that the linking element follows movement of the cyclically movable element to thereby slide the second part of the compressor relative to the first part of the compressor and pivot the compressor about the axis.

Claims

exact text as granted — not AI-modified
1 . A refrigeration system comprising: 
 a fluid circuit circulating a refrigerant in a closed loop, the fluid circuit having operably disposed therein, in serial order, a compressor, a first heat exchanger, an expansion device and a second heat exchanger, the compressor being pivotable about an axis, the compressor having a first part and a second part slidably coupled to the first part; and    a linkage including: 
 a cyclically movable element; and  
 a linking element attached to the second part of the compressor and pivotably coupled to the cyclically movable element such that the linking element follows movement of the cyclically movable element to thereby slide the second part of the compressor relative to the first part of the compressor and pivot the compressor about the axis.  
   
   
   
       2 . The system of  claim 1  wherein the axis about which the compressor is pivotable comprises a first axis, the linking element being pivotable about a second axis relative to the cyclically movable element, the second axis being substantially parallel to the first axis.  
   
   
       3 . The system of  claim 2  wherein the movement of the cyclically movable element is in a direction substantially perpendicular to the second axis.  
   
   
       4 . The system of  claim 2  wherein the compressor comprises a first compressor, the fluid circuit having a second compressor, the linking element comprising a first linking element, the linkage including a second linking element attached to the second compressor and pivotably coupled to the cyclically movable element such that the second linking element follows movement of the cyclically movable element to thereby slide a second part of the second compressor relative to a first part of the second compressor and pivot the second compressor about a third axis.  
   
   
       5 . The system of  claim 4  wherein the third axis is substantially parallel to each of the first axis and the second axis.  
   
   
       6 . The system of  claim 1  wherein the first part of the compressor comprises a cylinder, and the second part of the compressor comprises a piston.  
   
   
       7 . The system of  claim 1  wherein the linking element comprises a connecting arm, and the cyclically movable element comprises a rod.  
   
   
       8 . The system of  claim 1  further comprising a motor drivingly coupled to the cyclically movable element.  
   
   
       9 . The system of  claim 8  wherein the motor comprises a linear motor.  
   
   
       10 . The system of  claim 8  wherein the motor comprises a rotary motor.  
   
   
       11 . The system of  claim 1  wherein the linking element is fixedly attached to the second part of the compressor.  
   
   
       12 . A vapor compression apparatus comprising: 
 a compressor having a first part and a second part slidably coupled to the first part, the compressor being pivotable about an axis;    a linkage including: 
 a cyclically movable element; and  
 a linking element attached to the second part of the compressor and pivotably coupled to the cyclically movable element such that the linking element follows movement of the cyclically movable element to thereby slide the second part of the compressor relative to the first part of the compressor and pivot the compressor about the axis; and  
   a motor drivingly coupled to the cyclically movable element.    
   
   
       13 . The apparatus of  claim 12  wherein the axis about which the compressor is pivotable comprises a first axis, the linking element being pivotable about a second axis relative to the cyclically movable element, the second axis being substantially parallel to the first axis.  
   
   
       14 . The apparatus of  claim 13  wherein the movement of the cyclically movable element is in a direction substantially perpendicular to the second axis.  
   
   
       15 . The apparatus of  claim 14  wherein the compressor comprises a first compressor, the fluid circuit having a second compressor, the linking element comprising a first linking element, the linkage including a second linking element attached to the second compressor and pivotably coupled to the cyclically movable element such that the second linking element follows movement of the cyclically movable element to thereby slide a second part of the second compressor relative to a first part of the second compressor and pivot the second compressor about a third axis.  
   
   
       16 . The apparatus of  claim 15  wherein the third axis is substantially parallel to each of the first axis and the second axis.  
   
   
       17 . The apparatus of  claim 12  wherein the first part of the compressor comprises a cylinder, and the second part of the compressor comprises a piston.

       19 . The apparatus of  claim 12  wherein the motor comprises a linear motor.  
   
   
       20 . The apparatus of  claim 12  wherein the motor comprises a rotary motor.  
   
   
       21 . The apparatus of  claim 12  wherein the linking element is fixedly attached to the second part of the compressor.  
   
   
       22 . A vapor compression apparatus comprising: 
 a plurality of compressors, each of the compressors having a respective piston slidably coupled to a respective cylinder, each of the compressors being pivotable about a respective swivel axis; and    a linkage including: 
 a rod defining a longitudinal axis; and  
 a plurality of connecting arms, each of the connecting arms being attached to a respective one of the pistons and being pivotably coupled to the rod such that each of the connecting arms follows movement of the rod along the longitudinal axis to thereby slide each respective piston relative to each respective cylinder and pivot each respective compressor about each respective swivel axis.
