Valve regulator mechanism

Claim 1

THE VACUUM REGULATOR IS ADAPTED TO BE CONNECTED TO A SOURCE OF VACUUM WHICH MAY VARY, SUCH AS THE INTAKE MANIFOLD OF AN INTAKE MANIFOLD OF AN INTERNAL COMBUSTION ENGINE, NOT SHOWN, THROUGH A TUBE 25 AND IS ADAPTED TO DRAW A VACUUM IN A TUBE 34 WHICH HAS A SUBATMOSPHERIC PRESSURE WHICH IS REGULATED SO THAT IT VARIES ONLY IN ACCORDANCE WITH TEMPERATURES SENSED BY THE ELEMENT 36. THE REGULATION OF THE VACUUM IN TUBE 24 IS EFFECTED BY PROVIDING A CHAMBER 43 IN COMMUNICATION WITH THE TUBE 24 AND HAVING A VALVE PORT 51 TO CONTROL THE CONNECTION OF THE CHAMBER WITH THE TUBE 25 AND THE SOURCE OF VACUUM. THE PORT 51 IS ADAPTED TO BE CLOSED BY A VALVE 70 ON A FLEXIBLE DIAPHRAGM 56 WHICH FORMS ONE WALL OF THE CHAMBER 43. THE VALVE 70 IS ADAPTED TO CLOSE ON A PORT 78 WHICH IS FORMED ON A DISC 71 ATTACHED TO THE DIAPHRAGM AND WHICH SURROUNDS THE PORT 51. WHEN THE PORT 78 IS OPEN, ATMOSPHERE IS ADMITTED INTO THE CHAMBER. THE DISC 71 AND THE CENTRAL PORTION OF THE DIAPHRAGM 56 ARE SHIFTED TO OPEN AND CLOSE ONE OR THE OTHER OF THE PORTS 51 OR 78 BY A BAIL STRUCTURE ATTACHED TO THE DISC 71 IN THE FORM OF LEGS 76, 77 WHICH EXTEND THROUGH APERTURES IN THE DIAPHRAGM, SAID A PIN 80 ATTACHED TO THE LEGS. THE PIN 80 IS POSITIONED BY THE ACTION OF A LINER 37 PIVOTED BETWEEN THE SIDE PLATES 96, 97 AND WHICH ENGAGES THE ELEMENT 36. A SPRING 101 BIASES THE LEVER 37 TO THE ELEMENT 36 AND THE PRESSURE IMPOSED BY THE LEVER ON THE ELEMENT IS SELECTIVELY VARIABLE BY A LEVER 138, TO WHICH ONE END OF THE SPRING IS ATTACHED, WHICH LAYER IS MOVABLE ABOUT ITS PIVOT BY A CAM DISC 153. THE LEVER 37 IS CONNECTED WITH THE PIN 80 BY A DEFLECTABLE ARM 81, THE ANGULAR POSITION OF WHICH CAN BE FINELY ADJUSTED BY A SCREW 113 ARRANGED TO DEFLECT THE ARM ACCORDING TO ROTARY ADJUSTMENT OF THE SCREW. THE VACUUM REGULATOR IS CALIBRATED IN ONE RESPECT BY THIS ADJUSTMENT.
