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.
Claims38
An apparatus for servicing a coolant system adapted to receive coolant from a coolant supply, said apparatus comprising:
- 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.
A device for servicing a coolant system, said device comprising:
- an outer housing;
- a central body disposed within the outer housing, said central body having an internal bore and first, second, and third fluid ports communicating with said internal bore;
- a valve disposed in said internal bore, said valve adapted to attain a first position in which there is communication between said first fluid port and said second fluid port, and a second position in which there is communication between said first fluid port and said third fluid port;
- and
- a valve actuator operatively connected to said valve.
A system for servicing an automobile air conditioner, said system comprising:
- a coolant supply source;
- means for measuring a parameter of the coolant in the automobile air conditioner;
- and
- a device for servicing the automobile air conditioner, said device comprising:
- a central body;
- a valve disposed in said central body;
- and
- a valve actuator,
- wherein said valve is adapted to provide selective communication between the automobile air conditioner and (i) said measuring means, and (ii) said coolant supply source, responsive to an actuation force from said valve actuator.
A method of servicing a coolant system using a servicing apparatus attached to a measuring device and a coolant supply, said method comprising the steps of:
- attaching the servicing apparatus to the coolant system;
- and
- selectively switching between providing:
- (i) communication between the coolant system and the measuring device, and (ii) communication between the coolant system and the coolant supply.
A method of servicing a coolant system using a servicing apparatus attached to a measuring device and a coolant supply, said method comprising the steps of:
- attaching the servicing apparatus to the coolant system;
- and
- selectively providing a squeezing force to the servicing apparatus for switching between measuring a coolant system parameter and providing coolant to the coolant system.
