Axially sealing system for connecting fluid-passed conduits
View Patent ↗A system for connecting fluid-passed conduits which can be integrated into a refrigerant circuit of a heating, ventilation and air condition system of a motor vehicle. The system includes two connection blocks, wherein the connection blocks are joined together by a fastener having an elastically deflectable transfer component, the elastically deflectable transfer component compensates for a thermal expansion of the fastening means and the connection blocks.
1. A system for connecting fluid-passed conduits comprising:
two connection blocks formed from different materials, wherein the connection blocks are sealingly abutted by a fastening means; and
an elastically deflectable transfer component disposed adjacent a portion of the fastening means and pretensioned against one of the connection blocks by about three to about six times the minimum sealing force.
2. The system for connecting fluid-passed conduits according to claim 1 , wherein the elastically deflectable transfer component is a disc spring.
3. The system for connecting fluid-passed conduits according to claim 1 , wherein a first one of the connection blocks is formed from a first metal material and a second one of the connection blocks is formed from a second metal material.
4. The system for connecting fluid-passed conduits according to claim 3 , wherein the first metal material is aluminium and the second metal material is steel.
5. The system for connecting fluid-passed conduits according to claim 4 , wherein the fastening means extends through the first one of the connection blocks formed from the first metal material and is in threaded engagement with the second one of the connection blocks formed from the second metal material.
6. The system for connecting fluid-passed conduits according to claim 1 , wherein the connection blocks receive the fastening means therein.
7. The system for connecting fluid-passed conduits according to claim 1 , wherein the elastically deflectable transfer component is pretensioned at a temperature in a range from about 18° C. to about 24° C.
8. The system for connecting fluid-passed conduits according to claim 7 , wherein the elastically deflectable transfer component is dimensioned to compensate for a thermal expansion of the fastening means and the connection blocks in a temperature range of about −40° C. to about 200° C.
9. The system for connecting fluid-passed conduits according to claim 1 , wherein the system is adapted to be integrated into a refrigerant circuit of an air conditioning unit.
10. The system for connecting fluid-passed conduits according to claim 1 , wherein the system is adapted to be integrated into a refrigerant circuit of a heating, ventilation and air condition system of a motor vehicle.
11. An axially sealing system for connecting fluid-passed conduits comprising:
two connection blocks formed from different materials, wherein the connection blocks are sealingly abutted by a fastening means; and
a disc spring abutting a portion of the fastening means, wherein the disc spring is pretensioned against at least one of the connection blocks by about three to about six times the minimum sealing force.
12. The system for connecting fluid-passed conduits according to claim 11 , wherein a first one of the connection blocks is formed from a first metal material and a second one of the connection blocks is formed from a second metal material.
13. The system for connecting fluid-passed conduits according to claim 12 , wherein the first metal material is aluminium and the second metal material is steel.
14. The system for connecting fluid-passed conduits according to claim 12 , wherein the fastening means extends through the first one of the connection blocks formed from the first metal material and is in threaded engagement with the second one of the connection blocks formed from the second metal material.
15. The system for connecting fluid-passed conduits according to claim 11 , wherein the disc spring is pretensioned against one of the connection blocks at a temperature in a range from about 18° C. to about 24° C.
16. The system for connecting fluid-passed conduits according to claim 15 , wherein the disc spring is dimensioned to compensate for a thermal expansion of the fastening means and the connection blocks in a temperature range of about −40° C. to about 200° C.
17. An axially sealing system for connecting fluid-passed conduits comprising:
a first connection block formed from a first metal material and a second connection block formed from a second metal material, wherein the connection blocks are sealingly abutted by a fastening means; and
an elastically deflectable transfer component abutting a portion of the fastening means, wherein the elastically deflectable transfer component is pretensioned against at least one of the connection blocks by about three to about six times the minimum sealing force at a temperature in a range from about 18° C. to about 24° C. and is dimensioned to compensate for a thermal expansion of the fastening means and the connection blocks in a temperature range of about −40° C. to about 200° C.
18. The system for connecting fluid-passed conduits according to claim 17 , wherein the elastically deflectable transfer component is a disc spring.
19. The system for connecting fluid-passed conduits according to claim 17 , wherein the first metal material is aluminum and the second metal material is steel.
20. The system for connecting fluid-passed conduits according to claim 19 , wherein the fastening means extends through the connection block formed from the first metal material and is in threaded engagement with the connection block formed from the second metal material.
