Abstract
An apparatus, system and method for servicing a coolant system, such as, an automobile air conditioner are disclosed. In one embodiment, the apparatus may comprise a device for measuring a parameter of the coolant system; and means for selectively switching between providing: (i) communication between the coolant system and said measuring device, and (ii) communication between the coolant system and the coolant supply.
Claims20
A servicing device for servicing a coolant system, the servicing device comprising:
- an attachment portion connectable to the coolant system;
- a measurement device configured to be in fluid communication with the attachment portion via a measurement flow path when the servicing device is in a measuring mode of operation;
- a coolant source configured to be in fluid communication with the attachment portion via a coolant flow path when the servicing device is in a charging mode of operation;
- and
- a switching device configured to switch between the measuring mode of operation and the charging mode of operation by selectively blocking the measurement flow path of the coolant flow path.

A method of servicing a coolant system comprising:
- providing a servicing device connectable to a coolant source containing a coolant and having an attachment portion connectable to the coolant system, wherein the attachment portion is configured to be in fluid communication with either the coolant source or a measuring device;
- attaching the attachment portion to the coolant system;
- selecting a measuring mode of operation of the servicing device by blocking a coolant flow path and opening a measuring flow path;
- measuring a parameter of the coolant system with the measuring device;
- selecting a charging mode of operation of the servicing device by blocking the measuring flow path and opening the coolant flow path;
- and
- charging the coolant system by transferring the coolant from the coolant source through the attachment portion and into the coolant system.
