Abstract:
PURPOSE: To make the constitution of a multi-flow passage changeover device to be used for the change switchover or the like of heat operation fluid routes accompanying the cooling/heating operation changeover of a suction freezer type air conditioner, simple and inexpensive and free from leakage between flow passages.
CONSTITUTION: Respective flow passages 51-58 to be connected in changeover to the changed-over planes 2 of the valve chambers 3 of a box body 1 are arranged at intervals, and respective changeover grooves 21-24 are arranged on changeover planes 11 that butt against the changed-over planes 2 and slide. Elastic members 34-37 for push-pressing the changeover planes 11 against the changed-over planes 2 are arranged in a valve chamber. Even in a case in which slide places between the valve chambers 3 and a valve body 10 have been worn, leakage between respective flow passages does not occur as the changeover planes 11 of the valve body 10 are push-pressed against the changed- over planes 2 by means of the elastic members such as the springs 34-37.
