Application filed January 25, 1928. Serial No. 614,802.
To all whom it may concern:
Be it known that 1, JOHN citizen of the United Highland Park, in the B. Bunon'rr, a States, residing at county of Lake and tors in general and more particularly to pressure-regulators in which high pressures in storage-tanks are reduced to a comparatively low and steady working, or draw-off pressure.
The objects of vide a regulator which -ing pressure in close fine adjustment. Also member, for the regulator, freely and be self-adjusting on its seat. Also the invention are to pro will hold the worklimits and permit of to provide a valve which will work to allow the diaphragm great freedom of movement. Also reduce ing parts. Also to friction in the movprovide a regulator which will have a low range and a higher range of working pressures; and
will appear in In the accompanying other objects which the following description.
draw ings Fig. 1 isa vertical section of a pressurere ulator embodying my invention.
ig. 2 is an enlarged in Fig. 1.
view of parts shown Fig. 3 is a section on line 3-3 of Fig. 1.
Fig. 4 is taken on the line 44 of Fig. 1.
The device is built somewhat along the usual lines, with a body 4,
5.' This forms the pressure-chamber 7 an the enclosure 8.
High-pressure supply is'connected to the chamber 7 through the opening 10, shown Fig. 1.
the inlet-passage 9, and fluid at low pressure is drawn oil through in broken lines in The inlet-passage 9 extends into the boss passage 12 in the val 11, which projects into the chamber 7 below communicates with the ve-seat member 13,
which is threaded into the under-part of the boss 11.
The valve-seat member 13 is made of a hard material and is formed with the prois made separately and set into the seat member 13 and then secured by soldering.
- This permits the valve seat 14 to be accurately formed and inspected before the guide 15 is-secured in place.
Freely moving within the valve 16. This valve 16 is disc-shaped, or
relatively thin as to its diameter, and has a fiat face 16, a rounded back 16", and a narrow edge 16 in contact with the bore of the guide 15." The face 16 has an insert 17 of suitable material, such that when the valve 16 is pressed against the seat 14 in the operation of the regulator, an imprint willbe formed in the facing 17, making a true pres Y 1,491,192.. ES PATENT OFFICE.
has shifted or tilted cured to the diaphragm 6, will always engage the end 18 at a point near its center.
In this construction, just described, the diaphragm is allowed full freedom of movement, but pressure will be transmitted from the diaphragm 6 to the valve 16 in such a way that the valve 16 will be pressed evenly on its seat 14 regardless of any irregularity in the movement of the diaphragm 6. When pressure in the chamber 7 is below a certain amount, the pressure of the fluid in the passage 9 will force the valve 16' away from its seat 14, against the action of the d spring 21 which is seated in the bottom of the chamber 7 and presses upwardly on the stirrup 20. Fluid then enters through the inlet 12 and passes through the apertures ,15 into the chamber 7, filling the chamber 7 until pressure'on the larger area of the diaphragm 6, assisted by the spring 21, will close the valve 16 against pressure on the smaller area of the inlet 12.
The pressure at which the inlet 12 will be closed is regulated by adjusting means, C0111". prising a compression spring 22, a tension spring 23, and an adjusting screw 31.
The spring 22 presses on the outer surface of the diaphragm 6, and carries within it the spring-cup 25 which is supported-at the outer end of the spring 22, by the flange 25, formed on the the cup 25,is the tension spring 23 supported by the enlarged coil 27 which overlies the flange 25 The lower end of the spring 23 is formed to hold the yoke-member 29, upon which bears the point of the adjusting-screw 31. The adjusting-screw 31 is threaded through the top of the cover 5 and is operated to affect adjustments in the draw-off pressure.
The adjusting mechanism shown and just described, occupies small space, which is essential, and allows the diaphragm 6 to movefreely, because combined length of the two springs 22 and 23 is interposed between, the
When the parts of the regulator are in the position shown in Fig. 1, resistance is being applied to) the outward movement of the diaphragm 6 through both springs 22 and 23, but with the unit resistance of the smaller spring 23. Vhen the screw 31 is turned in a. ways, the spring 23 will be extended until the member 29 touches the bottom of the cup 25. Then, for further adjustments, resistance is ap lied directly through the spring 22 wit 'its greater unit resistance. Thus a. regulator is provided which has two ranges of adjustments-a low range and a higher range.
Having thus described my invention my claims are as follows:
1. In combination in a pressure regulator, a valve seat member having a projecting valve seat, a relatively thin valve having a flat face engaging said seat and a rounded back, a plunger having a flat inner end and a rounded outer end, a guide for said valve and plunger. and means operable by pressure within the regulator contacting with the rounded outer end of said plunger and thereby controlling the valve.
2. In combination in a pressure regulator having a chamber with an inlet opening having a projecting valve seat formed therearound, a relatively thin valve having a flat face cooperating with said seat and having a rounded back, a plunger having a flat inner end cooperating with the back of said valve and having a rounded outer end, a guide for said valve and plunger, av diaphragm. covering said chamber, a stirrup lator having a chamber with an inlet, a diaphragm covering said chamber and controlling said inlet, a compression spring pressing inwardly on the diaphragm, a tension spring mounted within and pressing inwardly on the compression spring, and an adjusting screw in engagement with said tension spring.
4. In a pressure regulator having a chambar with an inlet, a diaphragm covering said chamber, said inlet being controlled by movement of the diaphragm, a compression spring pressing inwardly on the diaphragm, a tension spring pressing inwardly on the compression spring, means mounted on the compression spring forming a limit for the elongation of the tension spring, and an adjusting screw bearing on the tension spring.
5. In combination in. a pressure regulator, pressure adjusting means comprising a. compression spring and a tension spring acting through said compression spring.
6. In combination in a pressure regulator having a chamber with an inlet, a diaphragm covering said chamber and adapted to control said inlet, a compression spring mounted to press inwardly on the diaphragm, a spring cup mounted onsaid compression spring, a tension spring mounted in and having its elongation limited by saidcup, and an ad usting screw engaging said tension spring.
In testimony whereof, I aflix my signature.
JOHN B. BURDETT.
