Specification of Letters Patent.
Patented June 4, 1907.
Application filed May 11, nice. Serial N0. 316,383.
To all whom, it may concern.-
Be it known that I, GUSTAF DALI'JN, a subject of the King of Sweden, residing at Stockholm, Sweden, have invented new and useful Im provcments' in Fluid-Pressure-Regulating :l)cviccs,. of which the following is a specification.
This invention relates to a fluid pressure regulating device and has for its object to maintain a certain constant gas pressure in a gas conduit notwithstanding variations of pressure in the conduit prior to reaching the pressure regulating apparatus.
, The invention includes the features of construction and arrangement and combination of parts hereinafter described and particularly pointed out in the claims.
The invention is illustrated in the accompanying drawings, in which,
Figure 1 is a vertical section of an embodiment of the invention, and Fig. 2 is a similar view of a modified form.
Referring by reference characters to this drawing the numeral 1 indicates a casing, one wall of which comprises a diaphragm 2, which is clamped between a flange 3 of the casing body and a ring 4. The diaphragm 2 is connected through a link 5 (clamped to the diaphragm by plates 5) with a lever 6 pivotally mounted on one or more fulcrum points 7 fixed 'to the casing 1. A bar 8 is inserted between a projection 9 depending from the lever 6, and a plate 10 against each of which it bears at its ends which are pointed. The plate 10 serves as a va ve and is mounted. to rock on fulcrum 11 fixer to the'casing or to a separate piece 15 secured to the casing. Between the lower part of thevalve plate 10 and. the lower part of the lever projection 9 is inserted a leaf spring 12.
13 indicates the fluid inlet and 14 the fluid outlet.
15 indicates the valve seat corresponding to the valve plate 10.
The strength of the blade spring 12 is adjusted in such a way that the spring counterbalances the fluid pressure on the diaphragm 2 when such pressure corresponds to that required in the conduit 14. Variations of said pressure will cause the diaphragm 2 to ascend or descend so that the blade spring is expanded or depressed and the valve plate 10 is correspondingly moved tow ard'or removed from the valve seat 15 by means of the bar 8, the flow of fluid through the valve being accordingly diminished or increased until the valve plate 10, owing to the diminished or decreased fluid pressure in the casing, returns to its original position controlled by the diaphragm 2 and the spring 12.
In the modified construction shown in Fig. 2 the end of the bar 8 itself constitutes the valve, thereby enabling the plate 10 to be omitted. The spring 12in this case is inserted between suitable points of the projection 9 and the casing 1. In order'that the spring will exercise the same pressurein its expanded as in its depressed position it is made in the form of a leaf spring inserted between suitably formed portions whereby it only bears against the parts with its end edges as illustrated. Almost the same eflect will result by the use of a spiral spring if it is made sufliciently long but in such a case its length would give the apparatus rather large dimensions.
It will be observed that the movable parts of the apparatus are movable on points or edges so that the friction will be reduced to a minimum thereby facilitating the working of the apparatus in a reliable and rapid manner.
Having thus described my invention what I claim is 1. In a fluid pressure regulating device, a casing having an inlet and an outlet for the fluid, a diaphragm closing the casing, a rocking lever, a connection between one arm of the lever and the diaphragm, a leaf spring, points on the other arm of said lever between which the said spring is inserted, a rocking valve plate and points on which the valve plate rocks.
2. In afluid pressure regulating device, a casing having an inlet and an outlet for the fluid, a diaphragm-closing the casing, a rocking lever, a connection between one arm of the lever and the diaphragm, a rocking valve, a bar, points on the other arm of the lever and the valve plate between which the bar is inserted, a leaf spring and points on the said arm of the lever and on the valve plate between which the leaf spring is inserted.
3. In a fluid pressure regulating device, a casing, a rocking valve plate points on which the valve plate rocks, a leaf spring, abutting f In testimony whereof I have signed my against one end of the valve plate, a dianame to this specification in the presence of phnagm, a lever, a bar and points on the two subscribing witnesses.
other end of the valve plate and on the lever GUSTAF DALEN. between which the bar is inserted, said lever Witnesses: and diaphragm being connected and said dia- WALDEMAR BOMAN,
