Portable type refrigerant recovery subsystem

Title:

Portable type refrigerant recovery subsystem

Document Type and Number:

Japanese Patent JP6117214

Kind Code:

B2

Abstract:

A portable, refrigerant recovery unit for transferring refrigerant from a refrigeration system to a storage tank. The unit includes two, opposed piston heads rigidly attached to respective piston rods that extend along a common fixed axis and are rigidly attached to a scotch yoke arrangement. In operation, incoming refrigerant is simultaneously and continuously directed to the opposing piston heads wherein the forces of the pressurized refrigerant on them counterbalance one another. The flow path of the refrigerant is designed to be isolated from the piston rods and drive mechanism to avoid any exposure to any contaminants in the refrigerant. However, to the extent the undersides of the piston heads and portions of the piston rods may be so exposed, a chamber is provided adjacent each piston underside to capture or collect any contaminants and direct them harmlessly back through one-way exhaust lines into the incoming refrigerant lines.
