Abstract

1496164 Valves UNITED GAS INDUSTRIES Ltd 21 March 1975 [5 April 1974] 15295/74 Heading F2V A diverter valve 14 has a member 15 movable between seats 17, 18 by a unidirectional motor 23 the motor circuit being interrupted, when the member closes one or other of the seats, by circuit breaking means 30, 31, 32 operated through means rotatable by the motor, and completed by a thermostatic switch 25 to move the member towards one or other of the seats according to the rise or fall of temperature. Reversal of the direction in which the valve member responds to temperature change may be effected by a thermal device 34, 36. Limit switches may consist of a conducting plate 28 with insulating peaks or, as in Fig. 11 (not shown) one of two cams (55, 56) may operate a switch (50), the second cam being provided for response reversal under control of a temperature sensor 35. Figs. 4, 5 (not shown) relate to a modification of the response reversal device. An alternative valve member and driving arrangement is described with reference to Fig. 12 (not shown). The valve may be used in air conditioners supplied with hot or chilled water.
