Abstract
A three-valve manifold including a first valve body, a second valve body, a third valve body, and a central chamber. The first valve body, second valve body, and third valve body are adapted to provide selective fluid communication between a canister of either refrigerant gas additive or refrigerant gas, a vacuum pump, and the low-pressure port of a chilling system. Methods for using the three-valve manifold are also disclosed. The three-valve manifold is a metallic, vacuum-rated, three-valve direct-charge device with integrated Schrader access, anti-backflow can tap, continuous bonding, and minimal internal volume—designed to safely support exact-charge servicing of flammable refrigerants in indoor and sensitive environments.

A three-valve manifold adapted for servicing a chilling system via said chilling system's low-pressure port;
- said three-valve manifold comprising:
- a first valve body having an internally threaded bore, said first valve body further having a longitudinal bore adapted for providing selective fluid communication between said externally threaded terminal end and the low-pressure port of the chilling system, said first valve body further having a selectively actuated valve mechanism;
- a second valve body having a terminal end adapted for engaging a vacuum pump, said second valve body having a longitudinal bore adapted for providing fluid communication between the vacuum pump and the low pressure port of the chilling system, said second valve body further having a selectively actuated valve mechanism;
- and
- a third valve body having a terminal end adapted for engaging the low pressure port of the chilling system, said third valve body having a longitudinal bore adapted for providing fluid communication between the vacuum pump and the low pressure port of the chilling system, said third valve body further having a selectively actuated valve mechanism;
- wherein said longitudinal bore of said first valve body, said longitudinal bore of said second valve body, and said longitudinal bore of said third valve body are arranged in a T-configuration, wherein said bores open into a chamber such that each said bore is in fluid communication with each of the other said bores.
