Impulse tool

Claim 1

IN AN IMPULSE TOOL, AN IMPROVED IMPULSE GENERATING MEANS COMPRISING A ROTATABLE HOUSING MEMBER HAVING A SYMMETRICAL, NON-ECCENTRIC, COAXIAL, INTERNAL CAVITY CONTAINING A PRESSURE TRANSMITTING FLUID, A SPINDLE MEMBER ROTATABLY DISPOSED IN COAXIAL NON-ECCENTRIC RELATION IN SAID CAVITY FOR RELATIVE ROTATION BETWEEN SAID HOUSING MEMBER AND SAID SPINDLE MEMBER, MEANS ON ONE OF SAID MEMBERS DEFINING A PLURALITY OF FLUID PRESSURE SEALING PORTIONS DISPOSED IN SYMMETRICALLY SPACED RELATION AROUND SAID CAVITY, A PLURALITY OF MOVABLE ELEMENTS CARRIED BY THE OTHER OF SAID MEMBERS IN SYMMETRICALLY SPACED RELATION AROUND SAID CAVITY, THE CONFIGURATIONS OF SAID CAVITY AND SAID SPINDLE MEMBER BEING SUCH THAT, DURING RELATIVE ROTATION OF SAID MEMBERS, SAID FLUID PRESSURE SEALING PORTIONS AND SAID MOVABLE ELEMENTS ARE ENGAGEABLE AT DIFFERENT DISTANCES FROM THE AXIS OF ROTATION OF SAID MEMBERS WHEREBY TO DIVIDE SAID CAVITY INTO A PLURALITY OF ZONES OF ALTERNATELY INCREASING AND DECREASING VOLUME, AND FLUID PASSAGE MEANS IN SAID OTHER MEMBER FOR SIMULTANEOUSLY COMMUNICATING THE RESULTANT INCREASING FLUID PRESSURE FROM THE ZONES OF DECREASING VOLUME TO ALL OF SAID MOVABLE ELEMENTS AT CERTAIN PREDETERMINED RELATIVE ROTATIONAL POSITIONS OF SAID MEMBERS SO AS TO URGE SAID MOVABLE ELEMENTS INTO MOMENTARY SEALING RELATION WITH SAID FLUID PRESSURE SEALING PORTIONS, WHEREBY TO GENERATE INTERMITTENT SUBSTANTIAL FLUID PRESSURE INCREASES IN SEALEDOFF PORTIONS OF FLUID IN SAID ZONES OF DECREASING VOLUME AND THEREBY TRANSMITTING ROTATIONAL TORQUE IMPULSES THROUGH SAID FLUID BETWEEN SAID MEMBERS.
