unirse NICOLAI H. KILLER, OF CARBONDALE, PENNSYLVANIA.
(DOIVIPRIEISSOR.l
Application ijled January '15, 1923. Serial No. 612,583.
T all eli/0m z' may concern.'
Be it known that I, NIooLAI H. HILLER, a citizen of the United States, and resident of Carbondale, in the county of Iiackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Compressors, of which the following is a specification.
'Ihis invention is an improvement in gas compressors and relates particularly to the intake or suction pipe connections, the main objects being to permit of the use of a smaller suction pipe, avoid'pulsation of the in the suction pipe, prevent the passage of liquid to the*cylinder7 and avoid the necessity for gauze strainers to prevent scale, dirt or other solid matter from passing into the intake valves or cylinder.
In carrying out my invention I provide a receiver or chamber closely adjacent to the compressor and connected to the compression chambers by separate open-ended nipples terminating materially above the bottom or lower wall of the receiver. The receiver is lpreferably of a capacity in excess of the capacity of one of the compression chambers, and the suction pipe to the receiver enters at such a point thatliquid or solid particles are deposited in the receiver before passing to'said intake nipples.
In the accompanying drawings I have illustrated my invention as applied to both a double acting and a single acting compressor.
In these drawings:
Fig'. 1 is a side elevation of a double-acting compressor provided with my improved construction, certain of the parts being shown in section.
Fig. 2 is an end view partly in section.
Fig. 3 is a front elevation showing my construction attached to a compressor having a pair of single acting cylinders, and
F ig. et is a side elevation of Fig. 3.
In Figs. 1 and 2 I have illustrated my invention as applied to a compressor having a horizonta ly disposed cylinder of the double acting type and provided with intakes 11 at opposite ends thereof, and a piston 12. Instead of connecting the suction pipe to the intakes by the usual form of manifold,
I provide a receiver or chamber 13 preferably of a capacity substantially equal to one and one-half times the capacity of the cylinder 10, and supported by a pair of projecting open-ended nipples 14 preferably directly secured to the cylinder at the intake thereof. The receiver 13 is mounted comparatively close to the cylinder, and the nipples 14 extend into the receiver to a point materially above the middle of the latter. The receiver intermediate of thetwo nipples 14, is provided with an intake 15, and a suitable coupling 16, for direct connection to the suction pipe. 'This intake 15 thus comes preferably below the upper open ends of the nipples 14.
The compressor in koperation draws first through one lnipple and then through the other, 4but these nipples are of such short length that little orno pulsation of the gas takes place within-them. AThe velocity of the gas entering the receiver at the intake 15 drops by lreason of the larger capacity of the receiver rather than directlyfrom the suction line, so that the pulsation is not transmitted back to the suction line. 1 Thus there will be a steady and uniform flow through the suction pipe. By preventing` pulsation in the suction pipe a very much smaller pipe may be employed, and still the proper filling of the cylinder on each piston stroke is insured. Due tothe drop in velocity ofthe gasas it enters the receiver, particles of scale, dirt or other solid matter will separate out and collect in the receiver,
and due to the position of the inlet ends of the nipples, such solid -matter will not be carried into the cylinder. Also any liquid which may be carried along by the gas will separate out in the receiver', and may be drawn off from the receiver when necessary by means of a small drain cock 17. The separation of liquid from the oas is particularly important when the compressor is used as the ammonia compressor of a refrigerating system, as particles of liquid ammonia carried into the compressor often cause trouble by reason ofthe low temperature and the water hammer effect. Furthermore the construction eliminates the necessity of a suction strainer of fine gauze which is ordinarily necessary and which offersmaterial resistance to the free flow of the gas. As the receiver is not in direct contact with the cylinder, the gas in the receiver is not heated by heat of the cylinder. Y
In Figs. 3 and 4 I have shown the same type of intake receiver and connections for two compresion chambers which are in separate cylinders 10a of the single acting type instead of at opposite ends of a single cylinder of the double acting type. The cylinders are shown as vertically disposed rather than horizontally disposed, and the nipples le are of elbow form.
As the invention relates primarily to the intake construction, I have not illustrated the outlet and other mechanical details ot the compressor. c Y
Having thus described my invention, what I claim as new and desire to secure Letter latent is:
l. A compressor havingv plurality ci :ompression chambers provided with separate intakes, achaniber disposed closely adjacent to said compressor, separate nipples. extending 'troni sait intakes into said chamber, and terminating above the bottoni ci" the latter, and an intake to said chamber.
2. A compressor having plurality of compression chambers each provided with an intake., a chamber disposed closely 'adj acent to said con'ipressor, separate nipples extending sai-d intakes into sait, chainber and terminatingabove the bottoni oit the latter, and intake to saidV chamber a point intermediate to said nipples.
3. A compressor having a plurality oi"- vcompression chambers each proif'ided with an intake, a chamber disposed closely jacent to said compression chambers, separate nipples extending` from said intakes into said chainber and tei'ininatii'ig above the bottoni the latter, and an intake to said chamber, said receiver being ciC a capacityrat least equal 'to that et the capacity oi' one oi' said` compression e`=aniberse. i gas supply connectie. lt1- ple clianibered compressor, including' a re ceiver oi' a capacity in excess of the of a compression chamber, a v pair paratively short intake nipples into said receiver and adapted to be con: nected to the compressor intakes, and a suction pipe connection to said receiver.
5. Lgas supply connection ,i a multiple V :ered compressor including a chainber oY a capacity in excess o1 the cale-city ot the compressor cylinder, a pair of coinparatively short intake nipples projecting into said chamber and adapted to be connectez to the compressor intakes, and a suction pipe connection to said chainber` interinediate orf said nipples and below the upper ends thereof.
