1 Claim. (Cl. 251144) This invention relates to air compressors and the like and more particularly relates tovalves for air compressors.
An object of this invention is to provide a selfcontained valve suitable for use either as an intake or as an exhaust valve.
A further object of this invention is to provide a self-contained valve assembly having a body and a cap and a disc valve therein, the cap being retained on the body by friction, the assembly being capable of use interchangeably as an exhaust or intake valve.
A further object of this invention is to provide a valve for an air-compressor having limited disc movement. I
A further object of this invention is to provide a valve adapted for use both as an intake and as an exhaust valve which is readily replaceable without disassembly.
A further object of this invention is to provide a valve which is economical to manufacture in that the parts are simple screw machine products or stampings.
A further object of this invention is to provide a valve whose seat is outwardly disposed so that the finishing of the seat is an extremely simple operation adaptable to hand or machine lapping.
The above and other objects and features will in part be apparent and will in part be obvious from the following detailed description and the drawing, in which:
Figure 1 is a view in transverse section showing a cylinder of an air compressor having intake and exhaust valves constructed in accordance with an embodiment of this invention;
Fig. 2 is an exploded view showing parts of one of the valves;
Fig. 3 is a view in top plan showing a valve disc;
Fig. 4 is a view in side elevation showing an assembled valve.
In the following detailed description and the drawing, like reference characters indicate like parts.
In Fig. 1 is shown a cylinder of an air compressor indicated at I and containing a piston l2 and a connecting rod I3. The cylinder is provided with a cylinder head [4 having intake and exhaust ports indicated at I6 and I1 respectively, each of which communicates with the interior of the cylinder. Ports [6 and H are designed to accommodate valves I8 to H! that function as intake and exhaust valves respectively. The valves are held in place by appropriate plugs 2| and may be gasketed to prevent leakage past the 2 valve bodies. A screen 23 may be positioned at the upper end of intake well I6 to strain air enteringintake valve I8, while a plug 24 closes the upper end of the exhaust valve so that compressed air from the exhaust valve can leave through an exhaust opening 26.
Valves l8 and [9 are identical in construction and design and can be used either as exhaust valves or as intake valves by merely reversing position in the valve ports of the cylinder head. One of the valves is shown in detail in Fig. -2, and in assembled form in Fig. 4, while in Fig. 3 the valve disc is shown.
The valve comprises a body 29 Of generally cylindrical form, a spring 30, a valve disc 3| seated on the spring and a cap or plug 32. The cap 32 and body 29- are so designed that the cap can be pressed into the end of the body and retained therein by friction.
The end of the body opposite the cap is partially closed by a head plate 33 in which a port 34 is formed in the central portion thereof. The
The body cap 32 is so machined that a plug portion 35 can be pressed into the open end of body 29. The inner end of the cap is machined to provide an annular valve seat 36 on which the valve disc can seat. The closed end of the cap 32 is provided with a port 3'! disposed in line with port 34. The outer end of the cap is provided with a flange 38 corresponding in diameter to the outer diameter of the body 29.
The valve disc is preferably circular and has a diameter corresponding to the outside diameter of valve seat 36. The disc may be provided at spaced points with lugs 39 which act to hold the valve disc in a centered position in the valve body and limit the travel of the valve disc so that the disc moves only the short distance between the valve seat 36 and the shoulder 34 in the valve body.
The valve is assembled by placing the spring within the body so that it rests on the bottom thereof, mounting the disc 3| on top of the spring, and pressing the cap 32 into the open end of the body. As shown in Fig. 1, when the valve is assembled, the spring 30 is compressed to such an extent that the valve disc is normally held against the valve seat 38. When so assembled the valve body and cap have generally the appearance of a cylinder having a bore extending axially through the same. However, as shown most clearly in Fig. 4, flange 3B is of slightly lesser diameter than the valve body 39 for ease in separating the cap 32 from the valve body 29 for disassembling the valve. When the valve is disassembledthe' va'lve seat 35 151111115 exposed .(Fig. 2) so that the valve seat may readily :and quickly be lapped either by hand or machine to restore the surface of the valve seat when necessary.
As shown in Fig. 2, the coils of the spring vary progressively in diameter from a smallest coi'l' 42 which fits against the central .portion .offdisc 3| to a largest coil 43 which :isaseatedxon shoulder 33; and, when the valve is open. air, as it flows between ports 31 and 34, can now between convolutions of the spring.
When a valve is mounted as shown attain-Fig. 1, it acts as an intake valve, and during the in- .take stroke of piston l2, the 'valve disc-of. intake valve 18 is drawn away from the valve seat and air can flow into the cylinder about the sides of the-valve disc.
The exhaust valve I9 is identical with intake valve l8 except that the position thereof is reversed so that on the exhaust stroke of piston l2 the valve discpf the exhaust valve I 9 israised otf its valve-seat and air can flow about the valve disc of exhaust valve l 9 and through the exhaust opening.
Each of the valves l8 and 1.9 canreadily-be removed and a new valve substituted by merely. removing theappropriate plug 2! from the well or :port in which the valve ismounted and lifting the valve free since each valve is a completely selfcontained unit, and a substitute valve can readily be slipped into position to replace the removed valve.
The embodiment of the invention .described .above and shown in the drawing may .be modified in various structural details without. departing either from the spirit or the scopenf ,the invention as set out in the appended claim.
Having described my invention what '1 claim as novel and desire to secure by Letters Patent is:
A reversible valve capable of functioning either as an intake or as an exhaust valve, said Valve comprising a hollow cylindrical body open at both ends, said cylindrical body having on the in? side spaced annular flanges, one of said flanges being adiacentone end of the body, the other iifiangeibeing nearithe middle of the body,'a hollow cylindrical, open-ended plug in the other end suit the body, the outer end of said plug having a .fiange of smaller diameter than the cylindrical body and abutting the end of said body, the inner end-of said mlugehaving a valve seat, a valve disk rhetweensthelinnermnd of said plug and the middle flange or the rcylindrical body, said valve disk CLARENCE F. .I-IAR'IZMAN.
