  • a bias member 76 such as a coil spring or other type of resilient member, is located within the bore 70 for biasing the latch handle 72 towards a desired position.
  • the second valve member 46 includes an attachment plate 86 for securing the rotary valve 12 to the work piece handling device 16.
  • the attachment plate 86 may be another type of attachment feature for securing the rotary valve 12.
  • the attachment plate 86 is secured to or formed as a single piece with a rotary member 88.
  • the rotary member 88 is generally cylindrical and includes a large cylindrical section 90 and a small cylindrical section 92 relative to the large cylindrical section 90.
  • the cylindrical sections 90 and 92 form an annular groove 94 between the inside face of the large cylindrical section 90 and the attachment plate 86.
  • a passage 96 extends between each of the ports 30 of the second valve member 46 and a port 98 at the open face of the large cylindrical section 90.
  • the number of ports 98 corresponds to the number of ports 54 of the first valve member 44. Likewise, if two ports 30 are used, there may be two passages 96 and two ports 98. In some variations, the passages 96 may split or merge within the second valve member 46 such that there are unequal numbers of ports 30 and ports 98.
  • the clamp 48 includes a pair of clamp pieces 106a and 106b that are received around the small cylindrical section 92 within the annular groove 94 of the first valve member 46.

  • the first valve member 44, the second valve member 46, and the clamp 48 are secured together using one or more fasteners (not shown).

  • the fasteners include heads, the heads may be received within recessed portions of the openings 110b.
  • the clamp 48 prevents the second valve member 46 from being freely separated from the first valve member 44, but allows rotational movement between the first valve member 44 and the second valve member 46.
  • the clamp 48 may also be regarded as a bearing member in combination with the cylindrical sections 90 and 92.
  • the attachment between the first valve member 44, the second valve member 46, and the clamp 48 provides sufficient rigidity to structurally support the work piece handling device 16 from the support arm 14.
  • the rotary valve 12 also includes a gap 99 between the clamp 48 and the attachment plate 86 when completely assembled.
  • the width of the clamp 48 may be designed to be slightly smaller than the width of the annular groove 94 such that the gap 99 is provided when the fasteners are tightened to urge the clamp 48 against the large cylindrical section 90. The gap 99 provides the benefit of reducing friction between the attachment plate 86 and the clamp 48 when the second valve member 46 is rotated between positions.
  • the second valve member 46 may be rotated between different rotational positions to selectively align the ports 98 of the second valve member 46 with the ports 54 of the first valve member 44.
  • An aligned position between the ports 98 and the ports 54 corresponds to the open position of the rotary valve 12 where the working fluid can flow through the passages 52 and 96 between the ports 28 and ports 30 (allowing flow between the working fluid source 29 and the work piece handling device 16).
  • Figure 6 illustrates an isolated view of the second valve member 46.
  • the large cylindrical section 90 of the rotary member 88 includes axial slots 120 at various circumferential positions around the large cylindrical section 90.
  • the slots 120 are located in four locations that are approximately 90° apart.
  • the slots 120 may have a different angular spacing, and fewer or more of the slots 120 may be used.
  • the second valve member 46 may not include the slots 120.
  • the slots 120 interact with the latch handle 72 to selectively lock or unlock the second valve member 46 relative to the first valve member 44.
  • the bias member 76 biases the latch handle 72 into locked engagement with one of the slots 120.
  • the operator actuates the latch handle 72 against the bias force of the bias member 76 to release the latch handle 72 from the given slot 120.
  • the operator may then freely rotate the second valve member 46 and work piece handling device 16 relative to the first valve member 44 until the latch handle 72 aligns with another of the slots 120.
  • the operator may release the latch handle 72 such that the bias member 76 urges the latch handle 72 into locked engagement with another one of the slots 120 to rotationally lock the rotary valve 12.
  • Figure 7 illustrates one example wherein the second valve member 46 is in an open flow position with the ports 98 aligned with the ports 54.
  • Figure 8 illustrates another position wherein the second valve member 46 is rotated such that the ports 98 are out of alignment with the ports 54. In this position, since the ports 98 and 54 are not aligned, the passages 96 are not in fluid communication with the passages 52. Therefore, the working fluid is unable to flow between the working fluid source 29 and the work piece handling device 16.
