ROTARY 'AIB-COMPRESSOR.
Specification of Letters Patent.
Patented. oet. e, Tear.
Application led July 1, 1916. Serial No. 107,053.
To all 'whom t may concern:
Be it known that I, PHILIP D. HrBNnR, a citizen of the United States,lresiding at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Rotary Air-Com pressors, of which the following is a specilication.
This invention relates to rotary air-compressors, although-it may be usefully employed in pumps, etc.
The object of my improvements is to provide a simple and inexpensively constructed machine of this type which will perform a relatively high amount of work with a minimum consumption oftpower, which will operate with little vibration and wear, and deliver a fluid from the compressor at a uniformly high pressure.
The invention consists in the novel construction, adaptation and combination of parts, as will be hereinafter described and claimed.
Tn the accompanying drawings, Figure 1j is a transverse vertical section -of a fluid compressor embodying my invention. Fig. 2 is a horizontal section taken substantially through 2-42 of Fig. l. Fig. 3 is a fragmentary sectional view similar to Fig. 1 with the rotor and a slide shown in dierent relative positions from which they are represented in Fig. 1. Fig. 4 is a detail sectional view taken substantially through 4 4 of Fig. 1.
Referring to the drawings, the numeral 5 designates the machine casing or cylinder. j
Extending lconcentrically through the bore thereof is a power-drivenr shaft '6 lupon which is rigidly mounted a rotor 7 This rotor is of a substantially elliptical form in transverse section and of a size to have its major axis equal to the internal diameter of the cylinder, or nearly so, when packing strips 8 are utilized tol lit against the peripheral surface of theA cylinder bore.
The cylinder is provided at diametrically opposite sides with chambers 9 to accommodate radially disposed plates or slides 10. Said chambers have communication through passages 11 with the branches 12 of a discharge pipe 13.
Provided in each of said passages is a seat 14 for an outwardly opening valve 15 which is yieldingly held in its closed position by means of a spring 16 interposed between the respective valve and a washer 17 whereby the tension of the respective spring is regulated through the agency of an adjusting screw 18. v
At' diametrically opposite sides of the cyhnder and in proximity of the respective slldes 10, are series of air-inlet openings 19 separated by diagonally arranged partitions 20, shown in Fig. 4. At the intake end of each of the series of openings 19 is a strainer 21 of wire gauze or an equivalent.
The slides 10 are advantageously provided upon their inner ends with suitable packmg or wearing strips 22 which are held against the rotor by the slides being pushed inwardly of the cylinder by means of springs 23 whose eective power may be regulated by adjusting screws 24. 4
Each of the slides is provided in its side remote from the adjacent inlet openings 19 with a recess 25 which extends from. the nner end of a slide to a distance therefrom suiicient to reach the associated passage 11 when the rotor is in approximately the position in which it is illustrated in Fig. 1.
The operation of the invention is as follows:
The rotor is driven in the direction indicated by arrows in Figs. 1 and 3, and as each of the extremities of the rotor revolve past the inlet openings119, the fluid to be compressed is drawn into the cylinder to follow the rotor while the fluid supplied to the cylinder in the preceding cycle of operation is compressed in advance of the major axis and the respective slides 10.
By reason, however, o f the recesses of the 'slides being in operative positions during the early portions of the inward movements of the slides, the springs 16 and such iuid pressure as obtains to the rear of the valves will prevent any of the fluid escaping from the cylinder into said discharge pipe until such pressure is sufficient to overcome the referred to opposing pressure plus that exercised by the springs.
When such fluid pressure is generated in .the cylinder, it will not be capable of escaping -into the discharge pipe until, during the ultimate portions of the successive cycles, the slide recesses 25 afford conduits for the compressed Huid to passages 11. Thus it will-be seen that the duid is compressed to a relatively high pressure within the cylinder,
and the check valves 15 work periodically and serve to minimize the amount of return flow of compressed air into the cylinder.'
What l claim as my invention 'is- 1. In apparatus of the class described, a cylinder provided with inlet and outlet openings, spring-pressed non-return valves provided for said outlet openings, a power-driven shaft extending concentrieally through the cylinder bore, an elliptic rotor mounted on said shaft, packing strips provided for the rotor, and radially disposed slides arranged for reciprocatory movement in the cylinder, springs tending to maintain said slides in contact with the peri hery of the rotor, said slides being provi ed with recesses whereby they serve as valves to regulate the delivery of Huid compressed in the cylinder.
2. ln a compressor, a cylinder provided with an inlet opening, and an outlet opening, a rotor, means to rotate said rotor, a reciprocatory member serving as an abutment for the rotor and also as a valve with respect to said outlet opening, and means cooperating with said member whereb uid compressed within the cylinder can e discharged through said outlet during only the latter part of each cycle of said rotors operation.
3. lln apparatus of the class described, a cylinder provided in its circumferential wall Laaaeea with a discharge passage, a rotor rotatable within the cylinder, a valve positioned in said outlet close to the inlet end of said discharge passage, and a slide coperating with the rotor to afford pressure within the cylinder and periodically interrupt communication between the interior of the cylinder and said valve.
4. lln apparatus of the class described, a casing provided with a cylindrical bore and havingfluid inlet anddischarge openings at opposite sides thereof, a substantially elliptical roter mounted within said bore, a slide provided with .a recess and serving as an abutment with respect tosaidrotor, a spring coperating with said rotor to effect reciproeatory movements of the slide whereby the recess thereof is moved into positions to alternately render said discharge opening operative and inoperative, and a springpressed valve positioned to close said discharge opening until the spring thereof is overpowered by fluid pressure obtaining Within the casing during the periods when said slide is in position to alordpan outlet through the recess thereof.
Signed at Seattle, Washington, this 26th day of June, 1916.
