Abstract
A valve core removal tool for an air-conditioning system includes a main body. The main body can include a system port, a first port, a second port, and a third port. The system port can be coupled to the air-conditioning system. The first port can be in fluid communication with the system port via a first channel. The first port can include a first valve and a first coupling. The second port can be in fluid communication with the system port via the second channel. The second port can include a second valve and a second coupling. The third port can be in fluid communication with the system port via a third channel. The third port can include a third valve, a third coupling, and a valve core assembly.

A valve core removal tool for an air-conditioning system, comprising:
- a main body defining a hollow chamber;
- a system port for coupling to the air-conditioning system;
- a first port in fluid communication with the system port via a first channel, the first port including a first valve for controlling flow between the system port and the first port and a first coupling;
- a second port fluid communication with the system port via a second channel, the second port including a second valve for controlling flow between the system port and the second port and a second coupling;
- and
- a third port in fluid communication with the system port via a third channel, the third port including
- a third valve for controlling flow between the system port and the third port;
- a third coupling, and
- a valve core assembly removably coupled to the third coupling and including
- a valve core engagement tool at a first end of the valve core assembly and configured to interact with the air-conditioning system through the system port, and
- a valve core shaft disposed at a second end of the valve core assembly and configured to move the valve core engagement tool within the main body.
