Connector device for charging and recharging a refrigeration circuit

摘要

The connector device comprises female and male parts in which one of the parts is coupled to evacuation or charging lines at the same time as the other part is coupled to a refrigeration circuit. Said parts of the connector use interconnection means in which an annular sleeve is mounted over the female part in order to support radially displaced keeper balls which are coupled in a depression in the male part in order to be immobilized in their position. Inside the male and female parts there are automatic closure valves which are coupled to a fixed element of the opposite part in order to open when coupling is complete. Each valve has a compression spring which urges it towards the closed position, thus automatically closing off during the disconnection operation. <IMAGE>
