Adjustable valving arrangement for positive displacement rotary type energy converting devices

Claim 1

IN A POSITIVE DISPLACEMENT ENERGY CONVERTING DEVICE OF THE TYPE HAVING A CASING, A POWER DISK ROTATABLY MOUNTED IN SAID CASING, AT LEAST ONE ABUTMENT DISK ROTATABLY MOUNTED ON SAID CASING WITH THE OUTER PORTION OF SAID ABUTMENT DISK BEING IN SEALED ASSOCIATION WITH THE OUTER PORTION OF SAID POWER DISK DURING ROTATION OF SAID DISKS, MEANS FOR ROTATING SAID ABUTMENT DISK IN SYNCHRONISM WITH SAID POWER DISK, SAID POWER DISK HAVING AT LEAST ONE PROJECTION ON ITS OUTER PORTION AND SAID ABUTMENT DISK HAVING AT LEAST ONE RECESSED PORTION RECEIVING SAID PROJECTION DURING ROTATION OF SAID DISKS, AND A VOLUME-CHANGING WORK CHAMBER FORMED BETWEEN THE WALLS OF SAID CASING AND THE POWER DISK AND THE NON-RECESSED PORTION OF SAID ABUTMENT DISK AND ONE EDGE OF SAID PROJECTION, THE IMPROVEMENT COMPRISING: A SHAFT CONNECTED TO SAID POWER DISK AND HAVING AN AXIALLY DISPOSED HOLLOW PORTIN, SAID CASING HAVING A FLUID PASSAGE OPENING INTO SAID WORK CHAMBER, A ROTATABLY ADJUSTABLE TIMING SLEEVE SEATED IN SAID CASING AROUND SAID HOLLOW PORTION OF SAID SHAFT, SAID TIMING SLEEVE HAVING AN ARCUATE RECESS ON ITS INNER SURFACE ADJACENT SAID HOLLOW PORTION OF SAID SHAFT AND SPACED FROM SAID OUTER SURFACE OF SAID SHAFT, AND A PROJECTION IN SIAD SLEEVE CLOSING SAID RECESS AND SEALINGLY ENGAGING SAID OUTER SURFACE OF SAID SHAFT, AN OPENING IN THE OUTER SURFACE OF SIAD SLEEVE INTERCONNECTING SAID ARCUATE RECESS AND SAID FLUID PASSAGE, SAID SHAFT HAVING A PASSAGE OPENING AT ITS RADIALLY INNER END INTO SAID HOLLOW PORTION OF THE SHAFT, THE RADIALLY OUTER END OF SAID PASSAGE BEING ALTERNATELY OPEN INTO SAID ARCUATE RECESS AND CLOSED BY THE INNER PERIPHERY OF SAID SLEEVE PROJECTION AS THE SHAFT ROTATES RELATIVE TO THE SLEEVE, A MOVABLE END WALL MEMBER IN SAID ARCUATE RECESS, AND MEANS FRO MOVING SAID END WALL MEMBER TOWARD AND AWAY FROM SAID OPENING IN THE TIMING SLEEVE.
