  • the piston 76 has a central through bore 88 which is in coaxial alignment with the through bore 52 in the cap assembly 38.
  • a tubular sleeve 90 has one end fixed within the forward end of bore 52 against a shoulder 92 via a retaining ring 94 and extends coaxially and matably into the through bore 88.

  • a plurality of passages define a single fluid passageway 104 from the outer surface of the end portion 50 through the plug portion 42 and into the cylinder 100; as will be seen the passageway 104 does not open into the head end of the cylinder 100.

  • An annular seal 114 located in a groove in the counterbore 112 provides a seal with the tubular member 108 thereby assuring that the fluid must travel between the aperture 110 and the passageway 104.
  • the tubular member 108 extends through the cylinder 100 from the counterbore 112 in plug portion 42 into a counterbore 116 in the rearward facing surface 118 of the adaptor 40.

  • annular fluid passage 129 which communicates with radial passage 127.
  • the passage 129 permits fluid pressure to be applied to the rod end of the cylinder 100, with the piston 78 in its forwardmost position and, hence, aids in the initiation of rearward movement of piston 76 in response to pressure at the rod end.
  • a first fluid path is defined by passageway 102 through cap assembly 38 and communicates with the head end of the cylinder 100.
  • a second fluid path is defined by the passageway 104 through cap assembly 38, the aperture 110 and port 119, both in tubular member 108, and communicates with the rod end of the cylinder 100'. It is often desirable with fluid actuated devices to be able to automatically reduce the actuating pressure in the cylinder when the piston reaches the end of its stroke. Such pressure relief prevents the buildup of extreme pressure which could result in damage to seals, components, etc.
  • the valve assembly 106 in a manner to be presently seen, automatically provides such pressure relief at the end of the stroke of piston 76 in both its rearwardmost and forwardmost positions.
  • the outer surface of the tubular member generally has a circular crosssection which is substantially of the diameter of the bore 120 in head portion 78 and permits the piston 76 to reciprocate relatively thereto without interference.
  • the forward and rearward portions of the tubular member 108 are provided with flats, such as flats in FIGURE 3, such that with the bore 120 of head portion 78 located completely in alignment with either of these end portions then passages, such as passages 124, are defined which communicate the rod end with the head end of the cylinder 100.
  • An intermediate portion 126 of the tubular member 108 is maintained with the full circular cross section such that, when any portion of the bore 120 is in radial alignment therewith, the rod and head ends of the cylinder are substantially no longer in fluid communication.
  • the intermediate portion 126 is provided to be of an axial length such that the passage 124 is opened to communicate the rod and head ends of the cylinder 100 just prior to the completion of movement of the piston 76 to either its forwardmost or rearwardmost positions.
  • the valve assembly 106 is automatically operative to relieve fluid pressure at the ends of the stroke of the piston 76 to thereby protect the tool from damage as mentioned before.
  • the valve assembly 16 is placed in a condition by the operator in which the pressure line 12 from the source of fluid pressure 10 is connected to line 18 and the return line 14 is connected to line 20.
  • Actuation of valve assembly 16 can be by means similar to that used for actuation of the unit shown in the patent to Van Hecke, supra. Fluid under pressure then is transmitted to the head side of the intensifier 22 and fluid at increased pressure at the rod end is caused to flow out through the line 32.
  • This intensified fluid pressure is applied to the rod end of the cylinder 100 via the passageway 104, aperture and port 119; the passage 127 and passage 129 aid in the initial application of fluid pressure in the manner previously described.
  • the piston 76 With the piston 76 at its forwardmost position some of the fluid applied at the rod end of the cylinder 100 is transmitted to the head end of the cylinder 100 in the passage 124, thereby resulting in a pressure drop at the rod end.
  • the piston 76 is moved rearwardly a short distance the bore moves into alignment with the intermediate portion 126 hence closing the passages 124 and resulting in an increase in pressure at the rod end and hence an increase in the force on the piston 76.
  • the plug portion 42 is provided with an axially forwardly extending, centrally located, boss portion 130 which engages the central portion of the head portion 78 leaving a substantial clearance between the remaining, confronting surface 0f the head portion 78 and plug portion 42.
  • valve assembly 16 in accordance with the patent to Van Hecke, supra, could be provided with additional means for automatically reducing the pressure if it exceeds a preselected maximum on the return stroke to further protect the tool 24 as well as means for automatically relieving excessive pressure from the source 10 on the power stroke to thereby protect the intensifier 22, i.e., on the power stroke the pressure fluid is applied to intensifier 22.
  • the tool 24 as specifically shown is used to set fasteners of the type shown in the patent t0 Huck, supra,
  • the forward end of the rod portion 80 of piston 76 is threadably connected to the rearward end of a tubular collet member 130 which is matably, slidably located within the anvil member 58.
  • the collet member 130 has a central, through aperture with a radially inwardly inclined, axially outwardly extending frusto conical surface portion 132 near its forward end.
  • the surface portion 132 tapers into a reduced diameter opening 134 at the forward end of the collet 130.
  • a plurality of gripping or chuck jaws 136 are located within the collet member 130 and have outer surfaces which mate with the surface portion 132.
  • the closing of the chuck jaws 136 is controlled by a follower assembly 138.
  • the following assembly 138 includes a tubular sleeve 140 which is stopped at the rearward end of the collet member 130 by means of a retainer ring 142.

  • the following member 150 in turn engages a tubular cap member 152 via an O-ring 154 located therebetween with the cap member 152 engaging the rearward surfaces of the chuck jaws 136.
  • the mating surfaces between the cap member 152 and chuck jaws 136 are contoured such that the jaws 136 are urged radially outwardly into engagement with the surface portion 132 of the collet member 130 as a result of the continuous axially forwardly directed force applied by the follower assembly 138.
  • the chuck jaws 136 are urged toward their closed position but are held open by a tubular, chuck jaw release member 156 which is slidably supported within the reduced diameter bore 134 at the forward end of the collet member 130.
  • a flange member and retaining ring assembly 158 is located in a groove intermediate the ends of the release member 156 and is engageable with the forwardmost surface of the collet member 130 to limit the axially inward movement of the release member 156.
  • a shoulder 160 on the rearward end of the release member 156 is engageable with a shoulder 162 in the bore 134 and limits the axially outward movement of release member 156.
  • the release member 156 serves a purpose to be presently understood.
  • the release member 156 engages the swaged collar and initially causes the chuck jaws to open to release the severed portion of the pin. As the piston 76 moves to its forwardmost position, the release member 156 drives the swaged collar out of the aperture 74 thus releasing the tool 24 for setting the next fastener. Note that the cylinder section 33 and nose section 34 define a continuous opening 164 completely through the tool 24 thereby permitting the ejection of broken pin portions or pin tails out the rearward end of the tool 24.
  • valve assembly 106 in addition to the other advantages mentioned also permits the assembly of all of the necessary fluid lines at the rear of tool 24 and through the cap assembly 38. In conventional constructions one of the fluid lines would have to be connected through the cylinder body portion 36, hence complicating its construction.
