【発明の名称】冷凍装置サービスアダプタ
Document Type and Number:
Japanese Patent JP3178842
Kind Code:
B2
Abstract:
A manually adjustable service adapter includes a manually adjustable actuation shaft for opening the valve of a charging port of a refrigeration system to permit the charging of refrigerant into such system. Actuation of such charging port results from an axially movable shaft in combination with one of two internal, axially slideable sleeves. The axially movable actuation shaft is manually adjustable by a rotatable knob which causes it to move axially but non-rotatably. Such axial movement of the shaft along with restriction of movement of one slideable sleeve upon abutment against the other slidable sleeve when the adapter is engaged to the charging port, opens the seal between the shaft and such one slideable sleeve while movement of the shaft with its end engaged to the valve of the charging port, opens such valve. Means are provided for preventing rotational movement of the axially movable shaft.
