Reciprocating hydraulic speed control device

Claim 1

A DEVICE FOR ADJUSTABLE CONTROL OF THE SPEED OF OPERATION OF AN INTERNAL COMBUSTION ENGINE WHICH COMPRISES: A FIRST FLUID SUMP; A FIXED-VOLUME HYDRAULIC PUMP CONTROLLED BY THE VEHICULAR SPEED OF AN AUTOMOTIVE VEHICLE AND OPERATIVELY CONNECTED TO SAID FIRST SUMP; A HYDRAULIC CYLINDER HAVING A FIRST AND A SECOND END; A FIRST HYDRAULIC FLUID LINE ADAPTED TO DELIVER FLUID FROM SAID PUMP TO THE FIRST END OF SAID CYLINDER; A SECOND HYDRAULIC FLUID LINE LEADING FROM SAID FIRST FLUID LINE TO SAID FIRST SUMP; MEANS FOR INTRODUCING HYDRAULIC PRESSURE FROM SAID FIRST FLUID LINE TO SAID SECOND FLUID LINE; MEANS FOR CONTROLLING HYDRAULIC PRESSURE IN SAID FIRST FLUID LINE BY CONTROLLING HYDRAULIC PRESSURE IN SAID SECOND FLUID LINE; A SECOND FLUID SUMP; A THIRD HYDRAULIC FLUID LINE ADAPTED TO DELIVER FLUID FROM SAID SECOND SUMP MEANS FOR INTRODUCING HYDRAULIC PRESSURE INTO SAID THIRD FLUID LINE; A FIRST PRESSURE REGULATING VALVE MOUNTED ON SAID THIRD FLUID LINE A SECOND PRESSURE REGULATING VALVE MOUNTED ON SAID THIRD FLUID LINE DOWNSTREAM OF SAID FIRST PRESSURE RGULATING VALVE SO THAT THE FIRST PRESSURE REGULATING VALVE WILL PREVENT PASSAGE OF FLUID UNDER PRESSURE FROM SAID THIRD FLUID LINE TO SAID SECOND PRESSURE REGULATING VALVE UNTIL A PREDETERMINED PRESSURE RELATED TO VEHICULAR SPEED IS ATTAINED IN THE FIRST FLUID LINE; A FOURTH HYDRAULIC FLUID PRESSURE LINE LEADING FROM SAID SECOND PRESSURE REGULATING VALVE; A BY-PASS SOLENOID VALVE OPERATIVELY CONNECTED TO SAID FOURTH FLUID LINE; A FIFTH HYDRAULIC FLUID PRESSURE LINE LEADING FROM SAID SOLENOID VALVE TO THE SECOND END OF SAID CYLINDER; A HYDRAULIC FLUID EXHAUST LINE LEADING FROM SAID SOLENOID VALVE TO SAID SECOND SUMP; A RECIPROCATING PISTON SLIDABLY DISPOSED IN SAID CYLINDER; A PISTON ROD MOUNTED ON SAID PISTON AND PROTURDING FROM THE FIRST END OF SAID CYLINDER; A CARBURETOR; A FLOW VALVE MOUNTED IN SAID CARBURETOR; AND MEANS CONNECTED TO SAID PISTON ROD AND TO SAID FLOW VALVE FOR OPERATING SAID FLOW VALVE UPON RECIPROCAL MOVEMENT OF SAID PISTON ROD AND PISTON.

Claim 2

A DEVICE FOR ADJUSTABLE CONTROL OF THE SPEED OF OPERATION OF AN INTERNAL COMBUSTION ENGINE WHICH COMPRISES: A FIRST FLUID SUMP; A FIXED-VOLUME HYDRAULIC PUMP CONTROLLED BY THE VEHICULAR SPEED OF AN AUTOMOTIVE VEHICLE AND OPERATIVELY CONNECTED TO SAID FIRST SUMP; A HYDRAULIC CYLINDER HAVING A FIRST AND A SECOND END; A FIRST HYDRAULIC FLUID LINE ADAPTED TO DELIVER FLUID FROM SAID PUMP TO THE FIRST END OF SAID CYLINDER; A SECOND HYDRAULIC FLUID LINE LEADING FROM SAID FIRST FLUID LINE TO SAID FIRST SUMP; MEANS FOR INTRODUCING HYDRAULIC PRESSURE FROM SAID FIRST FLUID LINE TO SAID SECOND FLUID LINE; MEANS FOR CONTROLLING HYDRAULIC PRESSURE IN SAID FIRST FLUID LINE BY CONTROLLING HYDRAULIC PRESSURE IN SAID SECOND FLUID LINE; A SECOND FLUID SUMP; A THIRD HYDRAULIC FLUID LINE ADAPTED TO DELIVER FLUID FROM SAID SECOND SUMP MEANS FOR INTRODUCING HYDRAULIC PRESSURE INTO SAID THIRD FLUID LINE; A FIRST PRESSURE REGULATING VALVE MOUNTED ON SAID THIRD FLUID LINE A SECOND PRESSURE REGULATING VALVE MOUNTED ON SAID THIRD FLUID LINE DOWNSTREAM OF SAID FIRST PRESSURE RGULATING VALVE SO THAT THE FIRST PRESSURE REGULATING VALVE WILL PREVENT PASSAGE OF FLUID UNDER PRESSURE FROM SAID THIRD FLUID LINE TO SAID SECOND PRESSURE REGULATING VALVE UNTIL A PREDETERMINED PRESSURE RELATED TO VEHICULAR SPEED IS ATTAINED IN THE FIRST FLUID LINE; A FOURTH HYDRAULIC FLUID PRESSURE LINE LEADING FROM SAID SECOND PRESSURE REGULATING VALVE; A BY-PASS SOLENOID VALVE OPERATIVELY CONNECTED TO SAID FOURTH FLUID LINE; A FIFTH HYDRAULIC FLUID PRESSURE LINE LEADING FROM SAID SOLENOID VALVE TO THE SECOND END OF SAID CYLINDER; A HYDRAULIC FLUID EXHAUST LINE LEADING FROM SAID SOLENOID VALVE TO SAID SECOND SUMP; A RECIPROCATING PISTON SLIDABLY DISPOSED IN SAID CYLINDER; A PISTON ROD MOUNTED ON SAID PISTON AND PROTURDING FROM THE FIRST END OF SAID CYLINDER; A CARBURETOR; A FLOW VALVE MOUNTED IN SAID CARBURETOR; AND MEANS CONNECTED TO SAID PISTON ROD AND TO SAID FLOW VALVE FOR OPERATING SAID FLOW VALVE UPON RECIPROCAL MOVEMENT OF SAID PISTON ROD AND PISTON.
