    2,913,166 REFRIGERATING APPARATUS John Weibel, Jr., Dayton, Ohio, assignor to General Motors Corporation, Detroit, Mich., a corporation of Delaware Application December 5,1955, Serial No. 551,008 1 Claim. (Cl. 230—58) This invention relates to refrigerating apparatus and more particularly to a sealed motor-compressor unit for use in various types of systems. It is an object of this invention to provide an improved means for reducing the torque reaction during starting and stopping of the motor and the associated compressor. 20 Another object of this invention is to provide a torque reaction snubbing means which transmits a minimum amount of noise and vibration from the motor-compressor unit to the casing which encloses the motor-compressor unit. A further object of this invention is to provide a torque reaction snubbing means which is simple and inexpensive and which will not interfere with the installation and removal of the motor-compressor unit from the casing. Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention is clearly shown. In the drawings:Fig. 1 is an elevational view, with parts broken away, showing the arrangement for supporting the motor-compressor unit within an outer casing;and Figure 2 is a plan view, with parts broken away, showing the relationship between the motor-compressor support, the outer casing, and the torque reaction snubber springs. . . Referring now to the drawing, wherein an illustrative embodiment of the invention has been shown, reference numeral 10 designates a sheet steel outer casing which serves to enclose a motor-compressor assembly generally designated by the reference numeral 12. The motorcompressor assembly includes the usual motor 14 having a drive shaft 16 provided with an eccentric portion 18 which operates suitable connecting rods 20 which, in turn, actuate pistons such as the piston 22 for compressing refrigerant, in accordance with well-known practice. For a more detailed description of the construction and operation of the motor-compressor unit shown herein reference is hereby made to copending application, Ser. No. 517,603, filed June 23, 1955, now Patent No. 2 855 139. The outer casing 10 is provided with suitable motor supporting ledges 24 on which the lower ends of conventional unit mounting springs 26 rest. The upper ends of the springs 26 serve to engage the underside of lugs 60 28 formed on the motor-compressor assembly 12 so as to support the weight of the motor-compressor assembly 12 in accordance with well-known practice. The springs 26 prevent the direct transmission of motor and compressor noise and vibration from the assembly 12 to the 65 casing 10. . . In a motor-compressor unit of this general type the torque reaction during the starting and stopping of the 1,866,154 Ell --------------------July 5,1932 2,130,835 Bixler-----------------Sept. 20,1938 2,365,673 Benson----------------Dec. 26,1944 2,463,035 Heitchue--------------Mar. 1, 1949 2,500,751 Halfvarson------------Mar. 14,1950 2,735,613 Calling----------------Feb. 21,1953 2,801,045 Philipp-----------------July 30,1957 FOREIGN PATENTS 483,269 Italy------------------July 23,1953
