About. The present invention will be described with particular reference to a spring-loaded bellows regulator. It will be appreciated that the selected aspects have application in the relevant fluid environment and application. . U.S. Pat.No. 5,303,734 discloses a predecessor regulator, the disclosure of which is incorporated herein by reference. I do. BRIEF DESCRIPTION OF THE FIGURES The invention may take physical form in certain parts and arrangements of parts. Preferred embodiments of the present invention will be described in detail in this specification, and the accompanying drawings forming a part of the invention. Shown on the side. FIG. 1 is a longitudinal sectional view of a novel pressure regulator formed in accordance with the present invention. FIG. 2 is a longitudinal sectional view of a modified regulator used as a back pressure regulator. Detailed Description of the Preferred Embodiment Referring now to FIG. 1, there is shown a preferred embodiment of the present invention. In the state, the high pressure fluid enters the inlet A of the body 19 and then proceeds to the poppet chamber B. Room Fluid flows from B through orifice 20 to chamber C through movable poppet 22 and orifice. It is controlled by an opening between the disk drive chamber 21 and the disk drive. After the fluid enters chamber C, the fluid flows Exit the body 19 via exit D. The fluid pressure in the chamber C acts on the movable bellows face plate 16. The bellows face plate 16 is provided with a poppet stem 18 extending through the orifice 20. It is connected to. The poppet stem is associated with the poppet 22. Bellow surface The plate 16 is welded to the flexible bellows 15 and the flexible bellows 15 is 4 is welded. The bellows support collar is welded to the upper housing 17 and the upper The jing 17 is welded to the main body 19. The pressure acting on the bellows face plate 16 is regulated by the regulator spring 7 acting on the opposite side of the face plate. Against. When the pressure in chamber C overcomes the force exerted by the regulator spring The faceplate moves upwards, losing more force and pulls the poppet stem and poppet. Then, move the poppet until the poppet comes into close contact with the poppet seat. Once the poppet is seated Combination Then, further flow is stopped and a pressure rise occurs. The flow is through the outlet D and the chamber Upon exiting C, the pressure in chamber C is reduced and the regulator spring force reduces the fluid force on the faceplate. Surpass. This moves the faceplate, poppet stem, and poppet downward. , Thereby opening the orifice passage and restoring flow. Pressure setting can be changed by adjusting the amount of regulator spring force . This turns an adjustment knob 1 attached to an adjustment shaft 3 by a set screw 2. Achieved by: A spring compression nut 6 is screwed into the adjuster 3, The nut 6 is prevented from turning because the hexagonal part of the nut is This is because it slides in the groove machined in the housing 5. Therefore, the adjustment axis When rotated, the spring compression nut advances or retracts in the axial direction, and the bellows face plate The spring force acting on the back side of the spring 16 is increased or decreased. In addition to the main concepts described above, the regulator has a mechanism for preventing vibration. This It is housed in an O-ring catch 9 that fits snugly on the damper shaft 12 This is achieved by the O-ring 10. In this configuration, the bellows face plate 16 When responding to the change, it exerts a slight resistance to the movement of the bellows faceplate 16. group The par axle 12 provides a tight fit of the O-ring when the poppet is about to close. Seal required to stop all flow between poppet 22 and orifice seat 21 A taper is provided to prevent resistance. Another feature of this regulator is the return spring 11. This spring turns the adjustment knob. To fully retract the spring compression nut, thus completing any regulator spring force. When fully retracted, the bellows face plate moves upwards and the poppet is biased to To move toward the constellation. The main body base 23 having an access port for repairing the poppet 22 is Welded to the bottom. This port is a gage which is pressed against the seat by the set screw 25. Sealed by a sket 24. In the second preferred embodiment shown in FIG. 2, the poppet 22 'is placed in the chamber C The orifice 20 'is sealed on the upper surface, that is, on the opposite surface. In this configuration, the assembly Mouth D can be used as a back-side regulator that becomes the inlet and mouth A becomes the outlet. You. The poppet stem 18 'is of short length and the poppet can be adapted to the configuration of FIG. Turn it over and seal it to the upper seat. In this way, the pressure in the inlet D is bellow and And acts on the regulator spring to provide a predetermined pressure to lift the poppet from its seat. This It controls the flow (and pressure) of the fluid to outlet A as desired with a back pressure regulator. . In substantially all other respects, this embodiment differs structurally and mechanically from the embodiment of FIG. Effectively equal. The invention has been described with reference to the preferred embodiments. Obviously, modifications and changes have It will occur to those skilled in the art when reading and understanding the specification. Such modifications and changes It is intended to include all such modifications as may come within the scope of the appended claims and their equivalents.
