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 removable core during processing, and ultimately install the core into the fluid access port at a suitable stage in the processing operations. 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.
Claims12
A service tool for connecting to a fluid access port that is operable with a removable core which is configured to control fluid flow through the fluid access port when the removable core is mounted within 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 removable core thereon so that the removable core is rotatable with the torque assembly.
