Application filed July 20,
This invention relates to an air compressing system or unit and more particularly to a type for use where compactness 1S an important factor and is highly desirable because of the limited space available for the use thereof.
Compressing systems have been designed heretofore but the difficulty with such prior known devices has been that more space is required for the use thereof than can be provided in some instances. In prior known devices it has been the custom to use a compressor as one unit, an oil separator as another, and a compression tank or chamber as a third unit. This requires a large space and a number of connections, such as those be tween units, all of which are undesirable and uneconomical. Furthermore, a vlarge num ber of connections means a great chance for leakage and results in lowered efhciency.
Our unitary compressing system includes two main elements, viz, the air compressor (preferably of the rotary type) upon which 1s mounted an air receiver. Within the air receiver is located an oil separating unit, thus effecting a considerable saving of materials and doing away with connections that would be required were the oil separator a separate unit. compactness is also'thereby effected. In the accompanying drawing in which like reference characters refer to like parts,- the single figure is an elevation, partly in section, of our air compressing unit.
in the drawing, 1 indicates an air compressor, preferably of the rotary type, which' draws the air to be compressed-thru an inlet member 2 and discharges the same thru the flanged. outlet portion 3 at thetop of the compressor and integral therew th. Upon the flange 3 of the compressor is mounted an air receiver 4, which is secured to the flange 3 of the air compressor by means of an inlet flange 5, the two flanges having machined faces and being secured together by means of bolts or machine screws of any desired type. The air receiver 4i comprises a reduced base portion 6 (integral with, and fromlthe lower portion of which extends, the flange 5), a compression chamber Tand a shouldered outlet neck 8, the chamber 7 constituting a wide- 192e Serial No. 123,623
bodied portion having severaltimes theca of the relatively narrow-necked pore.
pacity tion 8. l The lowerreduced portion 6-ispro+ videdwith a wall9 having an .opening'i'n which is inserted the'air compression cha n .The'neck 8'isclosed bymeans of a machined plate -;13,-in fwhich is insertedla safety valve 1 and an air-outlet pipe15'.- Altho we have bar inlet pipe 11. 1 VVithin the shouldered,
shown the air receiver offone size, it is obvious I that we may increase its diameter or height according to-requirements as to volume, etc.
Since most air" compressors, especially those of the rotary type, must operate with a large supply of oil,the'ch amber 7 is partially 7 filled with oil asshown atj-16, a valved return i line 17 being providedto conduct the oil'back to the compressor as may be required for its operation, [A c-leanout or discharge pipe 18 may also be providedfor the compression chamber either in the position shown or, at the base of the compressionchamber. j
The operation is as follows: a a .The oilvis sup'plied-tothe compression chamber 7 to a height approximately as illdicated' and the air compressor, 1 is started. Air is drawn .intothe compressor thru the inlet member 2 and discharged thru the pipe 11, thereby impinging upon the inverted bell portion of the oil separating unit 12.
The majority of oil taken up by the air in passing thru the air compressor is thus separated from the air, altho the air. must yet pass thru the screened portion of the oil separating unit 12 where the remainder of the oil is removed and the air passes out thru the pipe 15 directly to the ,point, of utilization as may be desired. Thus it will be observed that no separate air receiver or tank is required'to be interposed between our compressing, system and the point, of air utilization. The receiver 4: is large enough to maintain a clean, non-pulsating supply of air and yet the entire unit is quite compact and free from the usually large number of connections and piping required. The safety valve 14 prevents an unsafe pressure from accumulating in the system.
By the use of our invention, large and cumbersome air receivers or tanks may be eliminated and one unit occupying a very much reduced' spac'e is provided-in which the numerous connections required for prior known devices are dispensed With. 7
