Abstract

PURPOSE:To prevent the pressure within the apparatus from becoming extraordinarily high by letting the pressure within the apparatus escape out of the apparatus when the pressure therein exceeds a predetermined pressure. CONSTITUTION:When the pressure within the air conditioning apparatus 10B exceeds an operating pressure, a valve 23 is actuated by the pressure and moves upward against the dead weight of a weight 24 and the actuating force of a spring 28 thereby to open the opening 12A of a casing 12. Thus, air within the air conditioning apparatus 10B flows into the casing 12 through the opening 12A, and flows out of the casing 12 through a duct 16. As a result, the pressure within the apparatus is reduced to below the operating pressure of the valve 22, and at the same time, the valve 22 is actuated by the spring 28 and the weight 24 and moves again downward and blocks the opening 12A of the casing 12. Since the valve 22 is opened and closed by the pressure within the apparatus 10B, the valve 22 operates at once when the pressure within the apparatus 10B exceeds the preset operating pressure. By the operation of the valve 22, the opening 12A of the casing 12 is opened to let the pressure escape, thus preventing the pressure within the air-conditioning apparatus 10B from becoming extraordinarily high.
