Abstract

1,070,093. Valves. BRITISH THERMOSTAT CO. Ltd. Jan. 28, 1966 [Feb. 5, 1965], No. 5115/65. Heading F2V. A thermally-responsive pressure element (25, Fig. 1, not shown) at the outlet of a refrigerator evaporator (9) is connected to a chamber 24, Fig. 2, bounded by a diaphragm 22 which is attached to a movable closure member 15 controlling flow between the outlet of a condenser (3, Fig. 1) and the evaporator inlet. The closure member 15, Fig. 2, has a spherical part which is supported upon a complementary surface of a spring-loaded hollow element 17 to provide limited universal movement therebetween and hence accurate co-operation of the member 15 with its seal 14. An expansible metal sealing bellows 31 surrounds the valve stem 21 and is filled with refrigerant from the inlet 5 via a clearance 30 between the stem 21 and a neck 29. The diaphragm 22 is biased against movement by a spring 32, one end of which abuts a hollow piston 33 the position of which and hence the spring-loading being adjustable. The chambers 27 beneath the diaphragm 22 may be connected either to the evaporator or the valve outlet depending upon whether the pressure drop across evaporator is high or low. Since movement of the valve stem causes contraction or expansion of the bellows 31 the resulting flow of refrigerant through the clearance 30 results in damping of the action of the stem and closure member.
