Noncontact displacement measuring apparatus
Abstract
Abstract CONSTANT PRESSURE FROM THE NOZZLE ONTO THE SURFACE TO BE MEASURED, AND FURTHER DUE TO FLUID REACTION INTERNALLY AGAINST A REACTION SURFACE OPPOSITE THE ORIFICE. APPARATUS FOR PRECISELY MEASURING DISPLACEMENT OF RUNNING OR ROTATING OBJECTS WITHOUT BRINGING THE MEASURING PIECE INTO CONTACT WITH THE OBJECTS AND INCLUDES BODY PART PREFERABLY HAVING A UNIFORM CORSS-SECTION INTERIOR FLUID CHANNEL TERMINATING IN A SMALL JETTING ORIFICE WITHIN A NOZZLE PART DEVOID OF ANY SUBSTANTIALLY EFFECTIVE EXTERIOR FLUID PRESSURE RECEIVING OR REACTION SURFACE ADJACENT THE ORIFICE. THE UNIT OF A FLUID JETTING BODY NOZZLE IS SUPPORTED IN A FLOATING STATE SUCH THAT IT MAY CLOSELY FOLLOW THE SURFACE TO BE MEASURED, WHILE A FIXED CLEARANCE IS MAINTAINED BETWEEN THE NOZZLE AND THE SURFACE TO BE MEASURED DUE TO THE REACTION FORCE OF PRESSURE FLUID FED UNDER
