Abstract

A fitting assembly includes a fitting and a tube. The fitting has a fitting body having a straight through hole and an attachment or base port, connected to the through hole by a first passageway generally perpendicular to the through hole. The tube has an outer diameter smaller than the through hole allowing a first end of the tube to pass through the through hole. A seal is positioned in one of a circumferential slot in the tube and a circumferential slot in the through hole of the fitting body, the seal sealing a second end of the tube to the fitting body. A cover is sealingly attached to the first end of the through hole. One of the cover and the tube has a portion that extends into an intersection of the through hole and the first passageway, the portion having an aperture that prevents blockage between the attachment or base port and the second end of the through hole.

First claim

The invention claimed is:

1. A fitting comprising:
a fitting body having a straight through hole and a base port, the through hole having a first end and a second end, the base port connected to the through hole by a first passageway generally perpendicular to the through hole;
a seal positioned in the through hole of the fitting body at a location offset from the second end of the through hole; and
a cover sealingly attachable to the first end of the through hole, the cover including a portion extending into an intersection of the through hole and the first passageway, the portion having an end that provides a register surface for attachment of a tube to the fitting, the portion having an aperture that prevents blockage between the base port and the second end of the through hole.

2. The fitting of claim 1 , wherein the seal is positioned within a circumferential slot within the fitting body.

3. The fitting of claim 1 , wherein the cover comprises a threaded plug and an o-ring seal adjacent threads of the plug.

4. The fitting of claim 1 , wherein the cover comprises a plate with threaded fasteners, and an o-ring seal mounted on the plate.

5. The fitting of claim 1 , wherein the cover comprises a sensor.

6. A fitting assembly comprising:
a fitting body having a straight through hole and a base port, the through hole having a first end and a second end, the base port connected to the through hole by a first passageway generally perpendicular to the through hole;
a tube having a first end and a second end, each of the first end and the second end of the tube having an outer diameter smaller than the through hole, wherein the first end and the second end of the tube have a same diameter;
wherein during assembly of the fitting assembly the tube is movable from a first position to an assembled position;
wherein in the first position the second end of the tube is positioned outside of the fitting body extending from the first end of the through hole with a remainder of the tube extending from the second end of the through hole;
wherein the tube is moved from the first position to the assembled position by moving the second end of the tube through the first end of the through hole to the assembled position with the second end of the tube positioned within the through hole;
a seal positioned in at least one of a circumferential slot in the outer diameter of the second end of the tube and a circumferential slot in the through hole of the fitting body, the seal sealing the second end of the tube to the fitting body, the tube extending from the second end of the through hole; and
a cover sealingly attached to the first end of the through hole;
one of the cover and the tube having a portion that extends into an intersection of the through hole and the first passageway, the portion having an aperture that prevents blockage between the base port and the second end of the through hole.

7. The fitting assembly of claim 6 , wherein the second end of the through hole is configured to mate with a second end of the tube.

8. The fitting assembly of claim 6 , wherein the though hole is positioned on a same centerline of the tube.

9. The fitting assembly of claim 6 , wherein the cover comprises a threaded plug and an o-ring seal adjacent threads of the plug.

10. The fitting assembly of claim 6 , wherein cover comprises a plate with threaded fasteners, and an o-ring seal mounted on the plate.

11. The fitting assembly of claim 6 , wherein the first end of the tube has a smaller diameter projection having a hole therein to promote fluid passage through the first passageway.

12. The fitting assembly of claim 6 , wherein the cover comprises a sensor.

13. A cylinder assembly comprising:
a cylinder body having a first fluid port;
a manifold having a first fluid port; and
a first fitting assembly comprising a first fitting body having a through hole and a base port connected to the first fluid port of the cylinder body, the through hole having a first end and a second end, a first tube having a first end and a second end, the first tube having an outer diameter smaller than the through hole and the first end and the second end of the first tube have a same diameter,
wherein during assembly of the fitting assembly the tube is movable from a first position to an assembled position;
wherein in the first position the second end of the tube is positioned outside of the fitting body extending from the first end of the through hole with a remainder of the tube extending from the second end of the through hole;
wherein the tube is moved from the first position to the assembled position by moving the second end of the tube through the first end of the through hole to the assembled position with the second end of the tube positioned within the through hole;
the second end of the first tube sealing in the first fitting body, the first tube extending from the second end of the through hole of the first fitting body with the first end of the first tube sealingly mating with the first fluid port of the manifold, and a first cover sealingly attached to the first end of the through hole of the first fitting body, the first fitting assembly fluidly connecting the first fluid port of the cylinder to the first fluid port of the manifold.

14. The cylinder assembly of claim 13 , wherein:
the cylinder body has a second fluid port;
the manifold has a second fluid port;
and further comprising a second fitting assembly comprising a second fitting body having a through hole and a base port connected to the second fluid port of the cylinder body, the through hole having a first end and a second end, a second tube having a first end and a second end, the second tube having a geometry allowing the first end of the second tube to pass through the through hole of the second fitting body, the second end of the second tube sealing in the second fitting body, the second tube extending from the second end of the through hole of the second fitting body with the first end of the second tube sealingly mating with the second fluid port of the manifold, a second cover sealingly attached to the first end of the through hole of the second fitting body, the second fitting assembly fluidly connecting the second fluid port of the cylinder to the second fluid port of the manifold.

15. The cylinder assembly of claim 14 , further comprising a motor and a fluid reservoir attached to the manifold.

16. The cylinder of claim 14 , wherein at least one of the first cover or the second cover comprises a sensor.

17. The cylinder assembly of claim 13 , wherein the cover comprises a sensor.
