Abstract

The present invention is a unique motor comprising a containment chamber having thick walls surrounding a thin wall, is created when a plug is fusible joined. An inlet port and preferably a purging port are located in the thick walls. A motion is created when said expansion wall expands as said containment chamber is pressurized.

Claims

exact text as granted — not AI-modified
1 . An external expandable holding device comprising;
 a) first member having a external surface with an annular groove having protruding lips;   b) a resilient expansion sleeve is fusibly connected to the protruding lips alone the edge of the annular groove; flexurally to the first member for receiving the aperture of a second member;   c) a fillet along the lip and fillister along the expansion area to further relieve stress;   d) an expansion chamber with an external leading channel is defined between the first member and the expansion sleeve for receiving fluid;   e) wherein fluid is by means pumped to pressurize expansion chamber thereby the expansion sleeve is deformed to engage the second member;   f) whereby upon release of the pressure the expansion sleeve returns to the relaxed condition to release the second member.   
   
   
       2 . The expandable device according to  claim 1  wherein the holder and the expansion sleeve are cylindrical and the expansion sleeve expands radially outwardly to engage the second member. 
   
   
       3 . The expandable device according to  claim 2  whereby the fluid is a liquid. 
   
   
       4 . (canceled) 
   
   
       5 . (canceled) 
   
   
       6 . The expandable device according to  claim 2  whereby the holder is a shaft, a mandrel, an arbor, a clutch, a friction brake, a coupling, a damper, or a workholder and the second part is a tool, a workpiece, a hub, or a part. 
   
   
       7 . The expandable device according to  claim 2  whereby the holder is a molded piece. 
   
   
       8 . The expandable device according to  claim 2  wherein the expansion chamber is an annular expansion chamber extending around the circumference of the holder. 
   
   
       9 . The expandable device according to  claim 8  whereby the holding device comprises of a plurality of expansion chambers arrayed longitudinally. 
   
   
       10 . The expandable device according to  claim 2  wherein the expansion chamber extends around a portion of the circumference of the holder. 
   
   
       11 . The expandable device according to  claim 2  whereby the holding device comprises of a plurality of independent expansion chambers that are axial arrayed radially. 
   
   
       12 . The expandable device according to  claim 11  whereby the holding device comprises of a plurality of independent expansion chambers arrayed longitudinally: 
   
   
       13 . An internal expandable holding device comprising;
 a) a first member having a bore for receiving a second member;   b) a cover to the secured to the first member;   c) an expansion chamber with rounded corners to eliminate stress concentration extends to a thin wall as defined by the bore is defined within the first member between the cover;   d) the expansion chamber is joined by a channel to an aperture;   e) furthermore to reduce stress concentrations the bore surface has filsters along the thin wall;   f) wherein fluid is by means pumped to pressurize expansion chamber thereby the first member is deformed to exert force to the second member;   g) whereby upon release of the pressure the first member returns to the relaxed condition to remove the force from the second member.   
   
   
       14 . The expandable device according to  claim 13  wherein the holder and the expansion sleeve are cylindrical and the expansion sleeve expands radially inward to engage the second member. 
   
   
       15 . The expandable device according to  claim 14  whereby the fluid is a liquid. 
   
   
       16 . The expandable device according to  claim 14  whereby the fluid is a gas. 
   
   
       17 . The expandable device according to  claim 14  whereby the external surface of the resilient expansion sleeve has special holding features. 
   
   
       18 . The expandable device according to  claim 14  whereby the holder is a collet, a hub, a journal, a coupling, a clutch, a friction brake, or a workholder and the second part is a tool, a workpiece, a shaft, or a part. 
   
   
       19 . The expandable device according to  claim 14  whereby the holder is a molded piece. 
   
   
       20 . The expandable device according to  claim 14  wherein the expansion chamber is an annular expansion chamber extending around the holder. 
   
   
       21 . The expandable device according to  claim 14  wherein the expansion chamber is an annular expansion chamber extending partially around the holder. 
   
   
       22 . The expandable device according to  claim 20  whereby the holding device comprises of a plurality of expansion chambers arrayed longitudinally. 
   
   
       23 . The expandable device according to  claim 20  wherein the expansion chamber extends around a portion of the bore of the holder. 
   
   
       24 . The expandable device according to  claim 23  whereby the holding device comprises of a plurality of expansion chambers arrayed polar radially. 
   
   
       25 . The expandable device according to  claim 12  whereby the holding device comprises of a plurality of expansion chambers arrayed longitudinally. 
   
   
       26 . An external expandable lineal actuating device comprising;
 e) first member having a external surface;   f) a cover is secured to the first member;   g) an expansion chamber with rounded corners to eliminate stress concentration extending to a thin wall is defined within the first member between the cover;   h) wherein expansion chamber is joined by a channel to an aperture;   i) furthermore to reduce stress concentrations externally the thin wall is bordered with filsters;   j) wherein fluid is by means pumped to pressurize expansion chamber thereby the first member is deformed to exert force to the second member;   k) whereby upon release of the pressure the first member returns to the relaxed condition to remove the force from the second member.
