Abstract
A traveling service tool that is configured to removably attach to a fluid access port of a refrigerant system. The fluid access port can be the fluid access port described herein or an existing fluid access port. When used with the fluid access port described herein, the traveling service tool is configured to hold a core during processing. In an embodiment, the traveling service tool remains attached to and travels with the refrigerant system for the refrigerant system to be processed at two or more separate fluid processing stations.
Claims11
A service tool for connecting to a fluid access port that is operable with a core which is configured to control fluid flow through the fluid access port, the service tool comprising:
- a generally hollow cylindrical body having a first end, a second end and a longitudinal axis;
- a latching connecter at the first end of the generally hollow cylindrical body, the latching connector is configured to releasably connect the generally hollow cylindrical body to the fluid access port;
- a torque assembly disposed within the generally hollow cylindrical body, the torque assembly is rotatable relative to the generally hollow cylindrical body about the longitudinal axis;
- the torque assembly includes a fluid flow passageway through which fluid can flow, a poppet valve in the fluid flow passageway that controls fluid flow through the fluid flow passageway, the poppet valve is rotatable with the torque assembly relative to the generally hollow cylindrical body, and a seat defined on the torque assembly that is configured to hold the core so that the core is rotatable with the torque assembly,
- wherein the torque assembly projects beyond the second end of the generally hollow cylindrical body, and the poppet valve projects beyond the second end of the generally hollow cylindrical body.
A service tool for connecting to a fluid access port that is operable with a core which is configured to control fluid flow through the fluid access port, the service tool comprising:
- a generally hollow cylindrical body having a first end, a second end and a longitudinal axis;
- a latching connecter at the first end of the generally hollow cylindrical body, the latching connector is configured to releasably connect the generally hollow cylindrical body to the fluid access port;
- a torque assembly disposed within the generally hollow cylindrical body, the torque assembly is rotatable relative to the generally hollow cylindrical body about the longitudinal axis;
- the torque assembly includes a fluid flow passageway through which fluid can flow, a poppet valve in the fluid flow passageway that controls fluid flow through the fluid flow passageway, the poppet valve is rotatable with the torque assembly relative to the generally hollow cylindrical body, and a seat defined on the torque assembly that is configured to hold the core so that the core is rotatable with the torque assembly,
- wherein the generally hollow cylindrical body includes an exterior surface, and a circumferential detent groove is formed in the exterior surface between the first end and the second end and between an end of the latching connector and the second end.
A system comprising:
- a service tool for connecting to a fluid access port that is operable with a core which is configured to control fluid flow through the fluid access port, the service tool comprising:
- a generally hollow cylindrical body having a first end, a second end and a longitudinal axis;
- a latching connecter at the first end of the generally hollow cylindrical body, the latching connector is configured to releasably connect the generally hollow cylindrical body to the fluid access port;
- a torque assembly disposed within the generally hollow cylindrical body, the torque assembly is rotatable relative to the generally hollow cylindrical body about the longitudinal axis;
- the torque assembly includes a fluid flow passageway through which fluid can flow, a poppet valve in the fluid flow passageway that controls fluid flow through the fluid flow passageway, the poppet valve is rotatable with the torque assembly relative to the generally hollow cylindrical body, and a seat defined on the torque assembly that is configured to hold the core so that the core is rotatable with the torque assembly;
- and
- a first additional service tool that is configured to removably attach to the service tool.
