Abstract

1,132,431. Filter system. SERCK R. & D. Ltd. 11 Nov., 1965 [11 Nov., 1964], No. 45912/ 64. Heading B1D. Incoming fluid is switched from one filter or pair of filters to another by a pressure-responsive coanda device, and filtered fluid leaving the filter(s) on forward flow is partly diverted in reverse direction through the remaining filter. In Fig. 2, fluid is directed into passage 5 or 6 by pressure and suction transmitted through ducts 28, 29 which open to apertures 30, 31 in a cylinder 32 around which is generated a vortex which automatically switches from one side to the other continuously. In Fig. 1 (not shown), the coanda comprising nozzle (7) responds simply to clogging of one filter to switch flow to the other. Figs. 3 to 7 (not shown) illustrate systems in which two out of three filters are on filtering flow while the third is backwashed. Fig. 4 illustrates a tristable coanda which is controlled as in Fig. 2 by pressure transmitted through ducts (42, 43, 44) which lead to the downstream junction (38). Fig. 5 illustrates how the ducts may open into the cylindrical junction (38) at positions adjacent the main filtrate passages and circumferentially spaced therearound. Figs. 6, 7 illustrate an alternative in which the ducts open on to the flat faces of a triangular sectioned probe in the junction (38). Delay chambers (45, 46, 47) in the ducts determine the period of the switching action.
