Abstract

Apparatus is provided featuring a spindle having extending spindle portions configured with spindle glands; a compressor having extending compressor portions configured with compressor glands, and a snap ring configured to engage the spindle glands and the compressor glands in order to attach the spindle and compressor together, so that the compressor may be quickly released from the spindle by releasing an engagement between the snap ring, the spindle glands and/or the compressor glands.

First claim

What we claim is:

1. Apparatus comprising:
a spindle having extending spindle portions configured with spindle glands;
a compressor having extending compressor portions configured with compressor glands, and
a snap ring configured to engage the spindle glands and the compressor glands in order to attach the spindle and the compressor together, so that the compressor may be quickly released from the spindle by releasing an engagement between the snap ring, the spindle glands and/or the compressor glands; wherein
the extending spindle portions comprise inwardly extending flanges configured to receive and engage outwardly extending flanges of a tube nut that forms part of a diaphragm attachment; and
the snap ring is configured to engage the extending spindle portions in order to resist outward movement of the inwardly extending flanges and maintain a coupling with the tube nut.

2. Apparatus according to claim 1 , wherein
the spindle glands are configured far facing outwardly away from the center of the spindle;
the compressor glands are also configured for facing outwardly away from the center of the compressor; and
the snap ring is configured to engage the spindle glands and the compressor glands so as to form a shared exterior gland.

3. Apparatus according to claim 1 , wherein
the spindle glands are configured for facing inwardly towards the center of the spindle;
the compressor glands are configured for facing inwardly towards the center of the spindle or the compressor; and
the snap ring is configured to engage the spindle glands and the compressor glands so as to form a shared interior gland.

4. Apparatus according to claim 1 , wherein
the extending spindle portions are configured on diametrically opposite sides of an end portion of the spindle; and
the extending compressor portions are configured on diametrically opposite sides of a center portion of the compressor.

5. Apparatus according to claim 4 , wherein
the extending spindle portions and the extending compressor portions are configured to mate and interlock when the snap ring engages the spindle glands and the compressor glands in order to attach the spindle and compressor together.

6. Apparatus according to claim 1 , wherein the extending spindle portions, or the extending compressor portions, or both the extending spindle portions and the extending compressor portions, are configured as partial cylindrical portions having partial cylindrical glands.

7. Apparatus according to claim 1 , wherein the spindle has a longitudinal axis, and the extending spindle portions are configured to extend substantially in parallel with the longitudinal axis of the spindle.

8. Apparatus according to claim 7 , wherein the compressor has a central axis coaxial with the longitudinal axis of the spindle, and the extending compressor portions are configured to extend substantially in parallel with the central axis of the compressor.

9. Apparatus according to claim 8 , wherein the snap ring is configured to engage the spindle glands and the compressor glands on a plane substantially perpendicular to the longitudinal axis of the spindle.

10. Apparatus according to claim 1 , wherein the spindle glands and compressor glands are configured as, or formed part of, a protruding rim, edge, rib, or collar on the extending spindle portions or the extending compressor portions.

11. Apparatus according to claim 1 , wherein the coupling between the inwardly extending flanges of the extending spindle portions and the outwardly extending flanges of the tube nut primarily holds the compressor in place during operation.

12. Apparatus according to claim 1 , wherein
the snap ring comprises one side having a flat circumferential surface configured to engage the spindle glands; and
the snap ring comprises an opposite side having a corresponding flat circumferential surface configured to engage the compressor glands.

13. Apparatus according to claim 1 , wherein
the snap ring comprises an inner circumferential rim or surface configured to engage respective cylindrical wall portions of the spindle glands and the compressor glands.

14. Apparatus according to claim 1 , wherein the snap ring, the spindle glands and the compressor glands are configured to allow the compressor rotational freedom on a single axis.

15. Apparatus according to claim 1 , wherein the spindle is made by a cast spindle design, or by either turning and milling, based at least partly on the fact that the spindle is configured without difficult interior cuts.

16. Apparatus according to claim 1 , wherein the apparatus comprises, or forms part of, a valve, including a diaphragm valve.

17. A diaphragm valve comprising:
a spindle having extending spindle portions configured with spindle glands;
a compressor having extending compressor portions configured with compressor glands, and
a snap ring configured to engage the spindle glands and the compressor glands in order to attach the spindle and the compressor together, so that the compressor may be quickly released from the spindle by releasing an engagement between the snap ring, the spindle glands and the compressor glands;
wherein the snap ring comprises one side having a flat circumferential surface configured to engage the spindle glands; and the snap ring comprises an opposite side having flat circumferential surface configured to engage the compressor glands;
the extending spindle portions comprise inwardly extending flanges configured to receive and engage outwardly extending flanges of a tube nut that forms part of a diaphragm attachment, and
the snap ring is configured to engage the extending spindle portions in order to resist outward movement of the inwardly extending flanges and maintain a coupling with the tube nut.

18. A diaphragm valve according to claim 17 , wherein the coupling between the inwardly extending flanges of the extending spindle portions and the outwardly extending flanges of the tube nut primarily holds the compressor in place during operation.
