Claims
- 1. An apparatus for servicing a fluid system, comprising:
a body including a first lower port fluidly connected to a first upper port by a first channel; and a sealing member on the body configured to form a seal with an orifice of the fluid system when placed on the orifice.
- 2. The apparatus of claim 1, wherein the seal with the orifice increases when a reduced pressure is applied to the first upper port.
- 3. The apparatus of claim 1, wherein the sealing member comprises a resilient material.
- 4. The apparatus of claim 1, wherein the sealing member forms a sealing surface perpendicular to the first channel.
- 5. The apparatus of claim 1, wherein the sealing member is a flat rubber disk.
- 6. The apparatus of claim 5, wherein the rubber is a silicone rubber or butyl rubber.
- 7. The apparatus of claim 1, wherein the sealing member has a hardness between Shore OO durometer of 20 and Shore A durometer of 80.
- 8. The apparatus of claim 1, wherein the sealing member has a Shore A durometer of 20 to 60.
- 9. The apparatus of claim 1, wherein the sealing member includes a sizing ring and an o-ring.
- 10. The apparatus of claim 1, wherein the sealing member includes a bladder.
- 11. The apparatus of claim 1, wherein the sealing member includes a resilient ring with a sealing lip, the lip contacting an inner surface of the orifice to form the seal.
- 12. The apparatus of claim 1, wherein the sealing member is tapered.
- 13. The apparatus of claim 1, wherein the sealing member includes a sleeve and the apparatus further comprising a sleeve compressor external to the body and in contact with the sleeve.
- 14. The apparatus of claim 13, further comprising a threaded bolt extending into the body arranged to move the sleeve compressor thereby compressing the sleeve.
- 15. The apparatus of claim 13, further comprising a cam external to the body arranged to move the sleeve compressor thereby compressing the sleeve.
- 16. The apparatus of claim 13, wherein the sleeve compressor is threaded.
- 17. The apparatus of claim 1, wherein the body further comprises a second lower port fluidly connected to a second upper port by a second channel and a valve proximate to the second channel that stops fluid flow in the second channel when a fluid enters the second lower port.
- 18. The apparatus of claim 17, wherein the valve is a float valve.
- 19. The apparatus of claim 18, wherein the float valve includes a float ball.
- 20. The apparatus of claim 1, wherein the first upper port includes a valve.
- 21. The apparatus of claim 1, wherein the orifice is a radiator orifice.
- 22. An apparatus for servicing a fluid system, comprising: a body including a first lower port fluidly connected to a first upper port by a first channel and a second lower port fluidly connected to a second upper port by a second channel
a valve proximate to the second channel that stops fluid flow in the second channel when a fluid enters the second lower port; and a sealing member comprising a resilient material on the body configured to form a seal with an orifice of the fluid system when placed on the orifice, wherein the seal with the orifice increases when a reduced pressure is applied to the first upper port.
- 23. The apparatus of claim 22, wherein the valve is a float valve.
- 24. The apparatus of claim 23, wherein the float valve includes a float ball.
- 25. The apparatus of claim 22, wherein the sealing member forms a sealing surface perpendicular to the first channel.
- 26. The apparatus of claim 22, wherein the sealing member includes a flat rubber disk, a sizing ring and an o-ring, a bladder, a resilient ring with a sealing lip, or a tapered member.
- 27. The apparatus of claim 22, wherein the orifice is a radiator orifice.
- 28. A method for servicing a fluid system comprising:
draining a fluid from the fluid system; sealing a service apparatus onto an orifice of the fluid system by reducing pressure in the system, the service apparatus comprising:
a body including a first lower port fluidly connected to a first upper port by a first channel; and a sealing member on the body for forming a seal with the orifice; and filling the system with a fluid source fluidly connected to the first upper port.
- 29. The method of claim 28, wherein the body further comprises a second lower port fluidly connected to a second upper port by a second channel, and filling includes applying a reduced pressure to the second upper port to withdraw fluid from the fluid source, through the first channel and into the fluid system.
- 30. The method of claim 29, wherein the service apparatus includes a valve proximate to the second channel that stops filling when a fluid enters the second lower port.
- 31. The method of claim 30, wherein the fluid system is a cooling system.
- 32. A method for filling a fluid system comprising:
applying a reduced pressure to a service apparatus to withdraw fluid from a fluid source fluidly connected to a service apparatus, through the apparatus, and into the fluid system, the service apparatus forming a seal with the fluid system when the reduced pressure is applied.
- 33. The method of claim 32, wherein the service apparatus includes a valve proximate to a channel that stops fluid flow in the channel when the fluid enters the channel.
- 34. The method of claim 32, wherein the service apparatus includes a sealing member comprising a resilient material configured to form a seal with an orifice of the fluid system when placed on the orifice.
