REFRIGERATION APPARATUS Filed Nov. 1, 1930 Fig/I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII Patented Nov. 7, 1933 1,934,147 nEFmGERA'rIoN APPARATUS Ludwig neebel, Mannheim, Germany Appueetien November 1, 1939, serial No. 492,694, and in Germany December 5, 1929 9 Claims. (Cl. 62-115) My invention relates to improvements in refrigeration apparatus.
In the attempt to build reciprocating piston compressors which form a constituent part of a refrigerator in which compressors there is no necessity to render the piston or the crank shaft tight to the outside, different methods of construction have been developed which utilize the centrifugal force acting on the piston as the driving force. It is well known that the centrifugal force is evolved by giving the compressor cylinders a rotation about two axes of which one is outside the cylinders and the other passes through the central position of the pistons. Thus, the individual cylinders being subjected to a rotation about their own axes, the centrifugal force set up is caused to act on the pistons alternately in each direction.
One embodiment of my invention differs from the various constructions already known in that the centrifugal force does not set the compressor pistons or compressor cylinders in motion, but 'serves to prevent a part of the machine from rotating which is inside the double rotating system and which is provided with a special centrifugal weight for this purpose. In this embodiment, a hollow shaft and an eccentric fixed to this shaft are prevented from rotating about the shaft axis, but a compressor piston or a compressor cylinder attached to the eccentric strap is rotated about this axis and thereby given a reciprocating movement.
My invention resides in the improved apparatus and method of operation of the character hereinafter described and claimed.
For the purpose of illustrating my invention, anembodiment thereof is shown in the drawing, wherein Figure 1 is an elevational view, partly in section, of refrigerating apparatus constructed and operated in accordance with my invention; and v Fig. 2 is a fragmentary, sectional view, illustrating a modification.
In Fig.' 1, supporting structure 1 is built inthe' form of a disc and casing, and rotates about the shaft2 atuniformspeed. Inthecasingofthis supporting structure are connected one or more units'ireferred to hereinafter as refrigeratorsl' which consist chiefly of the compressor housing 3, the piston 4, the cylinder 5, the *tube 6, the atomizing jet 'I and the vaporizer chamber 8, and which rotate independently about the shaft 2. Each refrigerator however rotates, as well, about its axis 9, this motion being imparted to it bymeansofasearwheel 10,1Ihichenn8eswith the stationary pinion 11. 12 is an eccentric fixed on the hollow shaft 13, which shaft, in accordance with the invention, is prevented from revolving about its own axis by a centrifugal weight 14 which is also xed to it. The tube 13, 60 for this purpose, is rotatable with respect to the housing 3. The compressorpiston 4 is attached to the eccentric strap 15 and receives thereby a continuous reciprocating motion. The compressor cylinder 5 is built in one piece with the hous- 65. ing 3 and therefore continuously revolves with the said housing.
Fig. 2 shows a reversal of the arrangement shown in Fig. 1, and illustrates the case in which the compressor cylinder 5 is xed to the eccen- 70 tric strap 15 and reciprocates, while the compressor piston 4 is 'built in one piece with the housing 3 and therefore continuously revolves with the said' housing'.
The refrigerant, in both cases, drains continuously from the evaporating chamber through the passage 16, and is then compressed and forced past the flap valve 1'( into the inside of the housing 3, from whence it regains the evaporating chamber by means of the opening 18, the tube 6 and the atomizing nozzle 7.
