Fluid pressure regulator with fixedly and positively held spring having means to reduce hum

Claim 1

A FLUID PRESSURE REGULATOR COMPRISING, IN COMBINATION, A CASING, SAID CASING HAVING A FLUID INLET PASA FLUID OUTLET PASSAGE, A VALVE BETWEEN SAID FLUID INLET PASSAGE AND SAID FLUID OUTLET PASSAGE, A FLEXIBLE DIAPHRAGM POSITIONED WITHIN SAID CASING, SAID PASSAGES AND SAID VALVE BEING ON ONE SIDE OF SAID DIAPHRAGM, A PRESSURE PLATE HAVING AT LEAST A PORTION OF ONE SURFACE THEREOF ABUTTING SAID DIAPHRAGM ON THE OTHER SIDE OF SAID DIAPHRAGM AT AT LEAST A PORTION OF ONE SURFACE OF SAID DIAPHRAGM, A PRESSURE ADJUSTING SPRING POSITIONED WITHIN SAID CASING ON SAID OTHER SIDE OF SAID DIAPHRAGM, MEANS POSITIONED AT ONE END PORTION OF SAID PRESSURE ADJUSTING SPRING FOR FIXEDLY AND POSITIVELY HOLDING SAID PRESSURE ADJUSTING SPRING AGAINST ROTATION AND AGAINST SHIFTING WITH RESPECT TO SAID PRESSURE PLATE IN SAID ABUTTING POSITION AGAINST AT LEAST SAID PORTION OF SAID ONE SURFACE OF SAID DIAPHRAGM AND FOR SIMULTANEOUSLY HOLDING SAID PRESSURE PLATE AT AT LEAST SAID PORTION OF SAID ONE SURFACE THEREOF IN FIXED ABUTMENT AGAINST SAID DIAPHRAGM AT AT LEAST SAID PORTION OF SAID ONE SURFACE THEREOF, SAID MEANS INCLUDING A FIRST WASHER POSITIONED AT ONE SURFACE THEREOF AGAINST SAID PRESSURE PLATE AT AT LEAST A PORTION OF THE OTHER SURFACE OF SAID PRESSURE PLATE, SAID FIRST WASHER BEING IN CONTACT, AT AT LEAST AW PORTION OF ITS OUTER SURFACE, WITH AT LEAST A PORTION OF AT LEAST ONE CONVOLUTION OF SAID PRESSURE ADJUSTING SPRING AT SAID ONE END PORTION THEREOF, A FIRST FASTENER MEMBER EXTENDING THROUGH SAID DIAPHRAGM AND SAID PRESSURE PLATE AND SAID FIRST WASHER, SAID FIRST FASTENER INCLUDING A HERAD MEMBER AND A SHANK MEMBER DEPENDENT THEREFROM, SAID SHANK MEMBER HAVING, FOR AT LEAST A PORTION OF ITS LENGTH, A BORE THEREIN, SAID HEAD MEMBER CONSTITUTING A WEARING PLATE AND BEING POSITIONED ON SAID OTHER SIDE OF SAID DIAPHRAGM AND IN FIXED ABUTMENT AGAINST AT LEAST A PORTION OF THE OTHER SURFACE OF SAID DIAPHRAGM, A SECOND WASHER AXIALLY ALINED WITH SAID FIRST WASHER AND POSITIONED OVER AND IN CONTACT WITH AT LEAST A PORTION OF SAID ONE CONVOLUTION OF SAID PRESSURE ADJUSTING SPRING, AND A SECOND FASHENER MEANS FOR HOLDING SAID SECOND WASHER POSITIONED OVER AND IN CONTACT WITH AT LEAST A PORTION OF SAID ONE CONVOLUTION AND FOR HOLDING SAID WEARING PLATE FIXED AGAINST SAID DIAPHRAGM SURFACE, SAID SECOND FASTENER EXTENDING THROUGH SAID SECOND WASHER AND BEING FIXEDLY POSITIONED FOR A PORTION THEREOF IN AT LEAST A PORTION OF SAID BORE OF SAID SHANK OF SAID FIRST FASTENER, SAID VALVE INCLUDING A MOVABLE CARRIER ELEMENT AND STEM MEANS FOR MOVING SAID CARRIER ELEMENT UPON MOVEMENT OF SAID DIAPHRAGM, SAID STEM MEANS BEING ATTACHED TO SAID CARRIER ELEMENT AND ABUTTING SAID WEARING PLATE, AN ADAPTED BODY MEMBER POSITIONED IN SAID INLET PASSAGE AT ITS DOWNSTREAM END, SAID CARRIER ELEMENT BEING MOVABLY POSITIONED FOR AT LEAST A PORTION OF ITS LENGTH IN SAID ADAPTER BODY AND SLIDEABLY FITTED THEREIN AND SAID STEM MEANS EXTENDING THROUGH AND BEYOND SAID ADAPTER BODY, A FRUSTOCONICALLY SHAPED VALVE CLOSING SPRING POSITIONED IN SAID INLET PASSAGE AT ITS UPSTREAM END, SAID FRUSTOCONICALLY SHAPED VALVE CLOSING SPRING BEING ATTACHED AT ITS TOP PORTION TO SAID CARRIER ELEMENT, THE RATIO OF THE OUTSIDE DIAMETER OF THE TOP OF SAID SPRING TO THE OUTSIDE DIAMETER OF THE BOTTOM OF SAID SPRING TO THE AXIAL LENGTH OF SAID SPRING TO THE LENGTH OF THE PORTION OF THE CARRIER ELEMENT POSITIONED WITHIN SAID ADAPTER BODY WHEN SAID VALVE IS IN CLOSED POSITION BEING ABOUT 1 TO ABOUT 1.4 TO ABOUT 2 TO ABOUT 3.5, MEANS FOR CONTROLLING THE LOADING OF SAID PRESSURE ADJUSTING SPRING TO OBTAIN PREDETERMINED FLUID DELIVERY PRESSURES, SAID MEANS BEING OPERATIVELY ASSOCIATED WITH SAID CASING, AND MEANS POSITIONED AT AND IN CONTACT WITH THE OTHER END PORTION OF SAID PRESSURE ADJUSTING SPRING FOR FIXEDLY AND POSITIVELY HOLDING SAID PRESSURE ADJUSTING SPRING AGAINST SHIFTING WITH RESPECT TO SAID CONTROL MEANS AND WITH RESPECT TO SAID PRESSURE PLATE, SAID LATTER MEANS BEING OPERATIVELY ASSOCIATED WITH SAID CONTROL MEANS, WHEREBY EACH OF A PLURALITY OF FLUID DELIVERY PRESSURES CAN BE MAINTAINED WHEREBY T HE LONGITUDINAL AXIS OF SAID PRESSURE ADJUSTING SPRING WILL NOT BE SHIFTED DURING CONSTANT USAGE OF THE REGULATOR, WHEREBY SAID PRESSURE ADJUSTING SPRING WILL NOT BE ROTATED DURING CONSTANT USAGE OF THE REGULATOR, AND WHEREBY A SUBSTANTIALLY CONSTANT PREDETERMINED FLUID OUTPUT PRESSURE OF THE OUTLET FLUID IS OBTAINED WHILE HUM IS SUPPRESSED WITHOUT ANY WEAR OF ANY COMPONENT ELEMENT.
