Abstract

A stack or assembly of fluid, mechanical, and/or electrical components permits removal of some components for maintenance, without compromising the fluid integrity of the remainder of the assembly. A fastening bolt, attached to at least one fluid component, is screwed into a stacking bolt, attached to another fluid component, the bolts being screwed together inside the bore of an adapter plate. A resilient insert sits between the head of the stacking bolt and the bore. At least a portion of the bore has a continuous taper, such that the diameter of the bore decreases in the vicinity of the insert. The taper creates a reduced diameter hole on one surface of the adapter plate, thus preventing interference between fluid ports on an adjacent fluid component. The taper also prevents loss of the insert during transportation and storage, and prevents undesired extrusion of material of the insert when the components are fastened together.

Claims

1. In a stack of components, the stack including a component having a stacking bolt, the stacking bolt having a hollowed and threaded head portion, the stack including a component provided with a fastening bolt, and an adapter plate having a bore capable of receiving the stacking bolt and the fastening bolt, the fastening bolt being screwed into the head portion of the stacking bolt, the stacking bolt having a resilient insert disposed around the head portion, such that the insert is located between the head portion and the bore of the adapter plate, the adapter plate defining a superior surface and an inferior surface,

the improvement wherein at least a portion of the bore of the adapter plate has a continuous taper such that the bore has a diameter which decreases in a direction of the superior surface of the adapter plate.

2. The improvement of claim 1, wherein the insert has a chamfered corner, wherein the chamfer generally matches the taper of the bore of the adapter plate.

3. The improvement of claim 1, wherein the bore extends completely through the adapter plate, wherein the bore communicates with a first hole at the superior surface, the first hole having a diameter, and wherein the bore communicates with a second hole at the inferior surface, the second hole having a diameter, wherein the diameter of the first hole is less than the diameter of the second hole.

4. The improvement of claim 3, wherein the adapter plate has at least two bores, wherein the adapter plate is generally rectangular, wherein the adapter plate defines four corners, and wherein the bores are positioned in a vicinity of said corners, wherein the bores comprise mounting holes for components in the stack.

5. The improvement of claim 3, wherein the adapter plate has at least four bores, wherein the adapter plate is generally rectangular, wherein the adapter plate defines four corners, and wherein the bores are positioned in a vicinity of said corners, wherein the bores comprise mounting holes for components in the stack.

6. The improvement of claim 1, wherein the insert is affixed by an adhesive to the bore of the adapter plate.

7. In an assembly of components, the assembly including a component having a stacking bolt, the stacking bolt having a hollowed and threaded head portion, the assembly including a component provided with a fastening bolt, and an adapter plate having a bore capable of receiving the stacking bolt and the fastening bolt, the fastening bolt being screwed into the head portion of the stacking bolt, the stacking bolt having a resilient insert disposed around the head portion, such that the insert is located between the head portion and the bore of the adapter plate, the adapter plate defining a superior surface and an inferior surface,

the improvement wherein at least a portion of the bore of the adapter plate has a continuous taper, and wherein the bore has a diameter which decreases in a direction of the superior surface of the adapter plate.

8. The improvement of claim 7, wherein the insert has a chamfered corner, wherein the chamfer generally matches the taper of the bore of the adapter plate.

9. The improvement of claim 7, wherein the bore extends completely through the adapter plate, wherein the bore communicates with a first hole at the superior surface, the first hole having a diameter, and wherein the bore communicates with a second hole at the inferior surface, the second hole having a diameter, wherein the diameter of the first hole is less than the diameter of the second hole.

10. The improvement of claim 9, wherein the adapter plate has at least two bores, wherein the adapter plate is generally rectangular, wherein the adapter plate defines four corners, and wherein the bores are positioned in a vicinity of said corners, wherein the bores comprise mounting holes for components in the assembly.

11. The improvement of claim 9, wherein the adapter plate has at least four bores, wherein the adapter plate is generally rectangular, wherein the adapter plate defines four corners, and wherein the bores are positioned in a vicinity of said corners, wherein the bores comprise mounting holes for components in the assembly.

12. The improvement of claim 7, wherein the insert has a natural outside diameter which is essentially equal to a diameter of the bore of the adapter plate, and wherein the insert is affixed to the bore by an adhesive.

13. A stack of fluid components, comprising:

a) at least one component having a stacking bolt,

b) the stacking bolt having a hollowed and threaded head portion,

c) at least one fluid component having a fastening bolt,

d) an adapter plate having a bore capable of receiving the stacking bolt and the fastening bolt, wherein the fastening bolt is screwed into the head portion of the stacking bolt, within the adapter plate, and

e) a resilient insert disposed around the head portion of the stacking bolt, such that the insert is located between the head portion and the bore of the adapter plate, the adapter plate defining a superior surface and an inferior surface,

wherein at least a portion of the bore of the adapter plate has a continuous taper, wherein the bore has a diameter which decreases in a direction of the superior surface of the adapter plate.

14. The stack of claim 13, wherein the insert has a chamfered corner, wherein the chamfer corresponds to the taper of the bore of the adapter plate.

15. The stack of claim 13, wherein the bore extends completely through the adapter plate, wherein the bore communicates with a first hole at the superior surface, the first hole having a diameter, and wherein the bore communicates with a second hole at the inferior surface, the second hole having a diameter, wherein the diameter of the first hole is less than the diameter of the second hole.

16. The stack of claim 15, wherein the adapter plate has at least two bores, wherein the adapter plate is generally rectangular, wherein the adapter plate defines four corners, and wherein the bores are positioned in a vicinity of said corners, wherein the bores comprise mounting holes for components in the stack.

17. The stack of claim 15, wherein the adapter plate has at least four bores, wherein the adapter plate is generally rectangular, wherein the adapter plate defines four corners, and wherein the bores are positioned in a vicinity of said corners, wherein the bores comprise mounting holes for components in the stack.

18. The stack of claim 13, wherein the insert has a natural outside diameter which is essentially equal to a diameter of the bore of the adapter plate, and wherein the insert is affixed to the bore by an adhesive.

19. In a stack of components, the stack including a component having a stacking bolt, the stacking bolt having a hollowed and threaded head portion, the stack including a component provided with a fastening bolt, and an adapter plate having a bore capable of receiving the stacking bolt and the fastening bolt, the fastening bolt being screwed into the head portion of the stacking bolt, the stacking bolt having a resilient insert disposed around the head portion, such that the insert is located between the head portion and the bore of the adapter plate, the adapter plate defining a superior surface and an inferior surface,
