Rotational drive means for rotary valve in fluid pressure device
Abstract
Abstract THE DRIVE MEANS IS ESPECIALLY ADAPTED TO ROTATE A ROTARY VALVE IN A FLUID PRESSURE DEVICE HAVING STATOR MEANS AND ROTOR MEANS CONSTITUTING A FLUID STATOR-ROTOR MECHANISM. AN ACTUATING SHAFT OPERATIVELY CONNECTED TO THE ROTOR MEANS IS DISPOSED TO ROTATE THE ROTARY VALVE ONE ROTATION FOR EACH ROTATION OF THE ACTUATING SHAFT. THE ROTARY VALVE HAS A FIRST AXIS ABOUT WHICH IT IS DISPOSED TO ROTATE. THE ACTUATING SHAFT EXTENDS THROUGH A CENTRAL OPENING IN THE ROTARY VALVE AND HAS A SECOND AXIS DISPOSED FOR SUBSTANTIALLY CIRCULAR ORBITAL MOVEMENT ABOUT THE FIRST AXIS. THE ACTUATING SHAFT IS ALSO DISPOSED FOR ROTATIONAL MOVEMENT ABOUT THE SECOND AXIS AND HAS A COMBINED MOVEMENT COMPRISING SAID SUBSTANTIALLY CIRCULAR ORBITAL MOVEMENT AND SAID ROTATIONAL MOVEMENT. THE ROTARY VALVE AND THE ACTUATING SHAFT HAVE AN OVERLAPPING CIRCUMFERENTIAL DRIVING RELATIONSHIP THEREBETWEEN, WHEREBY THE ROTARY VALVE IS ROTATED IN RESPONSE TO THE COMBINED MOVEMENT OF THE ACTUATING SHAFT WITH THE ORIBITAL MOVEMENT SUBSTANTIALLY FREE FROM DRIVE INTERFERENCE.
