Refrigeration charging devices and methods of use thereof

A method of servicing a refrigeration system, comprising:

• providing a first fluid port of a servicing device to a fluid port of a fluid source;
• providing a second fluid port of the servicing device to a fluid port of a refrigeration system, wherein a portion of a plunger of the servicing device seals the second fluid port;
• wherein the plunger is adjustable between an open and closed position during use;
• contacting the plunger with a seal a or a valve of the fluid source to open the fluid source;
• wherein the plunger is capable of opening two types of fluid sources by piercing a seal of the fluid source or by depressing a valve of the fluid source;
• providing the fluid source to a first portion of a hand of a user;
• and
• actuating a lever of the servicing device with second portion of the hand to move the plunger such that fluid communication between the refrigeration system the fluid source is established.

A device for servicing a refrigeration system, comprising:

• a body comprising:
• a first fluid port, wherein the first fluid port operatively couples to a fluid source;
• a plunger, the plunger capable of opening two types of fluid sources by piercing a seal of the fluid source and/or by depressing a valve of the fluid source;
• a second fluid port, wherein the second fluid port operatively couples to a fluid port of refrigeration system;
• and
• a plunger seal at least partially disposed in the passage of the body, the plunger seal is configured to seal the second fluid port during use, wherein the plunger is adjustable between an open and closed position during use;
• and
• an actuator coupled to the body, and wherein, during use, downward movement of the actuator moves the plunger, opening the valve of the fluid source and/or piercing the seal of the fluid source while simultaneously adjusting the position of the plunger seal to allow fluid communication between the first fluid port and the second fluid port;
• wherein the fluid source is configured to be hand-held and the downward movement of the actuator is performed by a portion of the hand that is holding the fluid source.

A device for servicing a refrigerant system, the device comprising:

• a body comprising:
• a first fluid port, wherein the first fluid port is adapted to be coupled to a fluid port of a fluid source;
• a second fluid port, wherein the second fluid port is adapted to be coupled to a refrigeration system;
• a passage in fluid communication with the first and second fluid ports;
• and
• a plunger at least partially disposed in the passage, wherein the plunger is adjustable between a released position and an engaged position, and wherein the plunger is adapted to open a type of fluid source having a seal by piercing the seal of the fluid source and adapted to open a fluid source having a valve which is open when depressed by depressing the valve of the fluid source;
• and
• an actuator mechanically coupled to the body and to the plunger and disposed such that movement of the actuator moves the plunger to establish substantially continuous fluid communication between the first fluid port and the second fluid port.
