Abstract

1300460 Central heating systems K SCHICHL 19 Nov 1970 [20 Nov 1969 25 March 1970] 54964/70 Heading F4U [Also in Divisions Fl and F2] In a circulating pump, e.g. for central heating systems, having the pump impeller 6, Fig. 2, and a rotary mixer valve 7 arranged coaxially in the same casing, the rotary valve is adjusted into a desired angular setting by mechanical or hydrodynamic coupling with the impeller drive. The impeller continuously delivers through connection HV to the heating system and is supplied, depending on the setting of the valve 7, either through connection (KV), Fig. 1 (not shown), with hot water from the boiler, or through connection (HR) with return water from the heating system, the connection KR being connected to the boiler return. The valve is held in the desired setting'by a spring latch 20 engaging one of four depressions (24), Fig. 3 (not shown), in the periphery of the valve. Actuation of an electromagnetic control system, incorporating an eccentric plate 17 and linkages 16, 19, disengages latch 20 and moves a shaft 13 axially to temporarily engage a rotating cone 10 on impeller drive shaft 3, with the valve to thereby angularly adjust the latter to a new setting. In another embodiment, Figs. 4 and 5, an impeller 104 is continuously supplied through connection 1 and delivers to a helical channel 107 which discharges the water through a longitudinal slot (not shown) in the cylindrical wall 105 of a surrounding rotary mixer valve having two dividing vanes 106. The flow from the slot is directed, as shown in Fig. 5, tangentially of wall 105 so that when electromagneticactuated latching means 112 is temporary released from the respective depression 115, the valve is hydrodynamically rotated clockwise through 90 degrees to a new setting. Thus the connection 1 can be communicated with either the connection IV as shown, or with the connection II. One of the connections may be permanently closed so that there are only three effective connections.
