NOISE ELIMINATOR FOR REFRIGERATING APPARATUS Filed Jan. 12, 1953 4 JNVENTOR. a v John J. Preofle Afiorneys Patented Oct. 5, 1954 NOISE ELIMINATOR FOR REFRIGERATING APPARATUS Application January 12, 1953, Serial No. 330,786
3 Claims.
This invention relates to refrigerating apparatus and more particularly to an improved noise eliminator for use in a refrigerant system.
In a compression type of refrigerating system wherein refrigerant discharges directly from the outlet of a compressor into a refrigerant line leading to a condenser, the surges of refrigerant flowing through the system result in objectionable noises. It is recognized that a large number of muffler arrangements of various types have been used from time to time to eliminate these noises but these have usually been very expensive or have been ineffective to eliminate the noises which are caused by the surging refrigerant flowing to and through the condenser. It is an object of this invention to provide a simple and inexpensive means for eliminating such objectionable surges and resulting noise.
Another object of this invention is to provide a device which may readily be added to any system including existing installations with a minimum expense and inconvenience.
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:
Figure 1 is an elevational view partly diagrammatic showing the invention applied to a refrigerating system;
Figure 2 is an elevational view showing the relationship between the discharge valve and the noise eliminator; and,
Figure 3 is a side view with parts broken away showing the noise eliminator per se.
Referring now to the drawings wherein a preferred embodiment of the invention has been shown, reference numeral Hi generally designates a conventional reciprocating compressor having a projecting boss 52 through which the compressed refrigerant discharges. A conventional shut off valve assembly Hi is provided in the discharge line 16 which leads to the condenser I8.
In order to eliminate objectionable pulsations which result from the compressor discharging directly into the line leading to the condenser there has been provided a spherical chamber 20 directly at the outlet of the compressor through which the refrigerant leaving the compressor is required to pass before entering the line It. This chamber 20 is not directly supported on the compressor but is mounted on an adaptor plate 22 by means of the lines 24 and 25 which serve to convey the compressed refrigerant from the outlet 2 l2 into the chamber 20 and then into the valve housing It.
The adaptor block 22 is provided with a pair of passages 28 and 3!] as shown in Figure 3 which direct the refrigerant through the block. The block 22 and its associated parts may be readily attached to the outlet of a compressor merely by removing the cap screws 32 which normally hold the valve housing It in place on the compressor and then inserting the adaptor block 22 between the valve housing and the compressor and replacing the screws 32 which then serve to hold all of these parts together. For purposes of illustration, there has been shown a reciprocating type of compressor whereas it is obvious that certain aspects of this invention are equally applicable to systems using other types of compressors, such as rotary compressors.
In the embodiment hown, the reference numerals 4t, 42 and M designate the conventional receiver, expansion valve and evaporator respectively and the reference numeral 45 designates the suction line through which the expanded refrigerant returns to the compressor.
While the form of embodiment of the invention as herein disclosed constitutes a preferred form, it is to be understood that other forms might be adopted, as may come within the scope of the claims which follow.
What is claimed is as follows:
1. In a refrigerating system, a compressor, a condenser, an evaporator, and refrigerant flow connections for connecting said compressor, condenser and evaporator in series refrigerant flow relationship, said refrigerant flow connections including a shut-off valve at the outlet of said compressor and an adaptor block removably secured to the outlet of said compressor between said compressor and said shut-01f valve, a surge chamber carried by said adaptor block and means for directing the refrigerant discharged by said compressor through said surge chamber, and common means for securing said shut-off valve and adaptor block in assembled relationship to said compressor.
2. In a refrigerating system, a compressor having an inlet and an outlet, said outlet comprising a projecting boss, an adaptor block secured to said projecting boss and having a first passage communicating with said compressor outlet, a surge chamber, means for connecting the inlet of said surge chamber to said first named passage, said adaptor block having a second passage, means for connecting the surge chamber to said second passage, a shut-off valve housing having a fluid passage formed therein, means for removably holding said valve housing in assembled relationship relative to said adaptor block with said fluid passage arranged in communication with said second named passage, a condenser connected to the outlet of said valve housing, an evaporator, and means for conveying condensed refrigerant from said condenser to said evaporator and then back to the inlet of said 00111-1 pressor.
3. In a refrigerating system having a compressor, a condenser and an evaporator connected in refrigerant flow relationship, a shut-01f valve at the outlet of said compressor, a surge eliminator, and means for removably connecting said surge eliminator intermediate said compressor and said shut-off valve, said last named means comprising bolts passing through portions of said shut-off valve and said surge eliminator for holding said shut-ofi valve and said surge eliminator adjacent said compressor outlet.
