-DISTRiBUTER FOR REFRIGERATOFRS.
Specification of Letters Patent.
Application filed December 4, 1906. Serial No. 346,311.
Patented April 30, 1907.
To all whom it may concern.-
Be it kno wn that I, WILHELM WOLF, a subject of the King of Prussia, residing at Reisholz, near. Dusseldorf, in the Kingdom of Prussia, have invented certain new and useful Improvements in Distributers for Refrigerators, of which the following is a specification.
My present invention relates to a distributer for fluids (liquid or gas) in refrigerators,
being principally used for distributing liquids in machines operating with ammonia.
In refrigerators the pipes in which the liquid circulates, in order. to produce evaporation are subjected to diiferent stresses, forwhich reason the efliciency of the refrigerator is unfavorably affected. Attempts have been made to obtain a uniform distribution by only charging the distributing pipes for a time. The apparatus heretofore used for this purpose have however the drawback that all the pipe ends or openings are controlled by a single valve or other opening or closing agent, so that, after the machine, is constructed, the conditions resulting are rendered permanent and the order in which the various pipes are opened cannot be subsequently altered. In such apparatus heretofore used it was also not possible to automatically regulate the entrance of the li uid into the pipes independent of the suction force of the temperature .in the suction main of the compressor or in the vaporizer. According to my present invention the separate pipe openings of such a liquid controlling apparatus are opened in any desired manner and sequence, the valve or closing device for the pipe'openings not being common to all the pipes, so that the latter are not directly dependent upon each other and canbe opened independently. Further my invention consists in rendering the ad justment de endent upon the temperature or variations 0 pressure in the vaporizer or suction main of the compressor. In order, to obtain. this end with the ordinary means it is necessary to construct the driving mechanism for the closing devices of the pipes in such a manner that they canbeeasily moved 1 in certain directions, these movements being utilized in eflecting the regulation in the above sense. i
In the accompanying drawing several forms of the liquid distributer are shown, Figure 1 being. a longitudinal section of the arrangement with six ipes; Fig. 2 is a cross section, Fig. 3 is a simi ar section showing-another form of ithe valve for closing the pipes. Fig. 4 is a detail plan view of a plate for attaching the pipes and Figs. 5, 6 and 7 show the manner of operation, and form, of the valve operating cams.
1 designates the casing of the distributer,
into which the liquid or gas can be admitted through the cock 2. 'At the bottom of this casing the distributing pipes 8 are connected, by any suitable means preferably by coupling plates (1, Fig. 4, having a threaded aperture a into which the pipe is screwed and lateral bolt-holes a by means of which the late may be screwed onto the casing.- hese pipes are normally closed by the conical lift valves 6, which are provided with guiding extensions 4 which move in suitable bores in. the topof the casing. The lugs 3 enable the va ves to be removed and t he springs 5 to be inserted, by which latter the valves are normally pressed on their seats. In the casing 1 is provided a horizontal s indle 16 hav-' ing lugs 7 in different relatlve ositions. This spindle is rotated by the whee 9 which is driven in anfy desired manner from any rotating part 0 the distributer, so that the cams 7 are moved under the guides 4 one after the other and the valves thus raised. The liquid enters in corresponding order into the pipes 8.
In .Fig. 3 another form of the valve -is shown. Instead of the conical lift valves 6 plate springs 15 are used to close the pipes 8. One end of each of these springs covers the end of a pipe while the other end of said spring is attached to the casing. These plate springs are also operated by cams arranged under the same. Fig. 1 also shows how the stroke or time of o ening of the separate valves can be altered according to thetemperature or variations of ressure in the vaporizeror suction main of t e compressor.
13 designates the suction main by way of example, in which a regulator 10 is rovided. Said regulator has a piston 11 w ich can move up-and down in the cylinder. If the pressure in the suction main decreases the piston is raised by a spring while on the pressure increasing the piston is moved down and the spring is compressed. This movement of the piston is transferred by the lever 14 provided with a forked arm to the spindle 16, so that the latter is moved to the right when the pressure in the suction main sinks and the piston rises and to the left when the pressure in the suction main is increased. The
effect of this horizontal movement of the spindle 16 on the stroke of the valves is evi- 1 dent from Figs. 5, 6 and 7. Figs. 5 and 6 show how the cams 7 engages with the circular bottom of the cylinder 4. If the cam is moved laterally, as shown in Fig. 6, it remains in contact with the circular bottom for a shorter time. The valve will accordingly be raised to a smaller extent and will close' sooner. This operation of the cams may be assisted by suitably shaping their ends.
how weights 12 may be adopted to differently load the piston 11 so that a very wide range of regulation is afiorded.
The new device can of course be modified in various ways. Under some circumstances it maybe preferable to use another form of valve. Two or more valves'may if desired be united to a grou and raised together, the
essential feature eing that the separate valves'or the like of groups of valves or the like are, and can be moved independent of each other. Further the manner of regulat ing the operation of the valves according to the temperature or variation of pressure in the vaporizer or suction main can be carried out by other means than those shown in the drawing, although a piston subject to the pres sure of the gas may be regarded as the most practical means for the purpose. Instead of the rods etc, used to transfer the motion of the piston 11 to the spindle 16 any other suitable means may be adopted.
What I claim and desire to'secure by Letters Patent of the United States is 1.
