Application May 27, 1944, Serial No. 537,688 4 Claims. l My invention relates to air, gas, water, steam and oil pressure regulators, and has among its objects and advantages the provision of an im proved vibration eliminator. In the accompanying drawing: Figure 1 is a vertical longitudinal sectional view of a conventional pressure regulator embodying my invention. Figure 2 is a face view of the vibration elim ìnator, and (Cl. 50-26) 2 plane paralleling the weight plate 38. To the outer ends of the stems 56 are pivotally connected eccentrics 58, all the eccentrics being of the same size, weight and shape. The eccentrics are ar ranged at right angles to their respective stems 56, and the pivotal connection between the ec centrics and the stems are located at the ends of the eccentrics. Each eccentric includes a curvature 60 engag 10 ing the upper face of the weight plate 38, these Figure 3 is an edge View. curvatures ‘beingl located intermediate the ends In the embodiment of the invention selected of the respective eccentrics, but remote from the for illustration, Figure 1 illustrates a pressure free ends thereof, as shown in Figure 3, the op regulator comprising a lower casing I0 and a posite edges of the eccentrics are curved at 62 dome I2 between which a diaphragm I4 is 15 adjacent their free ends for engagement with clamped, the casing IIJ and the dome I2 being theinner face of the dome I2. ñxedly secured one to the other by bolts I6. The My invention maintains practically a constant casing I0 includes a boss I8 internally threaded pressure at more than one point on the top of the at 20 for connection with a fluid supply pipe, regulator diaphragm since the spring 40 rests on not shown; The casing also includes a wall 22 20 the post 42. The curvatures 60 are spaced 120 through which is threaded a valve oriñce 24. degrees apart and apply adjustment spring ten A valve 26 is seatingly related to the valve ori sion at three equally spaced points circumfer ñce 24 and is connected with one end of a lever entially of the axis of the diaphragm, to maintain 28, this lever being pivotally supported at 30 in a stiiîening force at these points between the the casing I0. The other end of the lever is pivotally con nected at 34 with a lever plate 3B between which and a weight plate 38 is clamped the diaphragm I4, although the surrounding portion of the dia 25 flexible diaphragm and the rigid dome I2, thereby preventing vibration of the diaphragm and the regulating valve. 'I‘he invention operates as a stiffening device, to be inserted between the flexible diaphragm phragm is free to ileX in response to variable pres 30 and the rigid body of a regulator, to eliminate the sure conditions eiîective thereon. A compression characteristic vibration of the flexible diaphragm spring 40 has one end mounted on a post ¿l2 lo and valve, thus eliminating the objectionable noise and the rapid wearing of the valve face. Without further elaboration, the foregoing will with a plug 44 threaded into a boss 48 on the 35 so fully explain my invention, that others may, dome I2. This plug may be adjusted to vary the by applying current knowledge readily adapt the cated centrally of the weight plate 38, the other end of the spring having abutting engagement tension of the spring 49.
