Abstract

883,386. Thermal switches; fluid-actuation of switches. ECKERFELD, A. Jan. 31, 1958, No. 3309/58. Class 38 (5). [Also in Groups XI and XIII] In Fig. 1, cold water controlled by a valve 2 flows through a pipe 4 provided with a heating coil 3, the water then passing into a chamber 6 which includes a bimetal diaphragm 7 engaged by a pin 11 of a switch 13 controlling the heating coil circuit. An adjustable throttle screw 10 is provided in a pipe 8 through which the water flows after leaving the chamber 6. Upon opening the valve 2, the pressure of the water causes the diaphragm to flex from the position shown and the switch contacts are closed. The layer of the diaphragm adjacent the chamber has a higher coefficient of expansion than the layer remote from the chamber, and upon being heated to a predetermined temperature by the heated water, causes the diaphragm to return to its original position and the switch contacts to separate. An indicator lamp 30 is connected across part of the heating coil. In the construction shown in Fig. 2, the surface of a bimetal diaphragm 27 nearest a chamber 19 is covered with a heat-insulating elastic material 29 which also surrounds the edge of the diaphragm, a switch-operating pin 26 which engages the diaphragm being enclosed by a corrugated packing 25. A pipe 18 connects the cold water supply pipe with the chamber 19 and flow of water through the apparatus is controlled by a valve 16 and a throttle 20, the latter causing the pressure in a chamber 22 to be lower than that in the chamber 19. The diaphragm is thus flexed from the position shown and contacts 28 are closed. The heatinsulating material 29 prevents the diaphragm from coming into contact with the cold water in the chamber 19.
