W/TNESSES VA TTOFQNEY `changes-'in the. temperature of the external The system shown in Figs. l,

2 and0 ls especially well adapted for use in this m nner, for the speed ofthe pump is increased., theI strangle valve U is adjusted to otter less resistance to the 'flow back to the heater trom the radiators as is desirable at this time. The apparatus shown in Figs. 1, 2 and 3 is less desirable where valves K controlling the dow through the individual radiators arer constantly being ad justed at the volition, for instance, of the occupants of different rooms heated by the diierent radiators.. In such a case it is desil-able, however, to automatically.compen sate for the changes. manually made in the' distribution of {iow through the circulating system, and this may Well be brought about by employing means responsive to the aecumulation of Wall or pressure at4 the top ofthe circulatingsystem to control the speed of the circulating pump. for this purpose is shown in Figs. l and 5.
The system shown in Fig. l differs" from that shown in Fig. l in the omission ot the i automatic strangle valve l) 1n the return line tro. the radiators. and in the replacement' o.. lhe throttle valve OA. in the steam line ot the pump driving motor Z by an.
automatic valve OB controlled by means responsive to the pressure'or accumulation of water at the top of the circulating; system. s shown in Fig. 4, moreover, the last mentionedmeans is speciticallyr diferent from the corresponding means shoivn in Fig. 1,L
but this has nothing to do with the essential dilerencein type between the system shown in Fig, l and that shownin Fig. Il. Advantageously in most cases a valve OC, which' may be a plain or throttle valve, is located in the return pipe 'from the radiators. T he valve 0B `.may be and is shown as being essentially 'the same as the valve O of Fig. 2, except that the valve member G10 of Fig. 5 is balanced and is moved toward and not away from its seat by an increased pressure in the chamber 08, and no leakage port 01" from the chamber @s is provided. The means shown in Fig. /l for controlling the valve OB comprises a tank JA located at the top of the circulating' system and receiv ving the dischargefrom the riser pipe H.
Water passes from the tank JA to the radiators through the pipe HA. A float J located Within thetank JA, and responsive to the rise and fall ot the Water level in the tank JA, operates a valve U, opening and closing the latter as the n ater level in the tank JA falls below and rises to a pre determined level. f The valve when openA connects a pipe lV to the tank JA. The
pipe MW is connected to a pipe ll", containing Water under pressure, by the rcstrlcted orifice A' branch,E pipe W3 runs from tholgipe W to the pressure chamber in the One arrangement the individual casing O8 of the turbine controlling."valve 0B. y The constant thoiuzh restricted flow of Water into the pipe ll' through the re stricted port `W`-` tends to build up ythe pressure in the pipe lV, and branch pipe W3 and valve chamber G8 to an equality with the pressure in the pipe il", so long' as the valve U is closed. In consequence, the pres sure in the chamber O, when the valve U closed, keeps the valve disk 01 against its seat. When the waterlevel falls in the tank JA sufiiciently, however, to lower the fioatJ10 and thereby cpenthe `valve U, the flow of water which then takes place from the pipe lV into the tank JA; reduces the pressure in the pipe W,- branch pipe XV and valve chamber O8, and thenvalve disk O1 then rises from its seat, more or lesa,-
depending;r on the extent to which the pressure 1n the chamber O8 is reduced. The
pressure in the chamber O8 'will obviouslydepend at this time on the\e.\;tent to which the valve lf 'is open andthe duration of the intervals during which the valve U is kept open. Y represents an overflow connection leadingr back to they heater from the` tank JA and openings,r to the latter, at a level above that at which the valve U will be closed by the iioat J1. the pipe Y forl'ned with a loop Y providing a Water seal, and With a vent conne@- ,ftdvantageously, as shown7 l tion, Y2 from the top of the les o'f this loop i which is connected to the heater.
With the system shown in Fig. a the distribution of ilow through the different radisarily large load is imposed on the pump at any time.
