HENRY BRIER, F DARTFORD, ENGLAND.

EMEIVER (ll? REFRIGERATING A PPARATUS.

Application filed March a, 1920.

To (ZZZ whom. it may oo iic'evm Be it known that I, HENRY Hence a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Dsrtford, llnglend, have invented at certain new and useful Improvementin Receivers of Refrigerating Apparatus. of which the following is e specification. The invention relates to improvements in receivers for use With refrigerating epperetus employiu either ordinary compression r multiple elicct compression. In such apparatus a valve adapted to regulete the inlet of the refrigerating: gas or liquefied gas to or-the outlet of liquefied gas from the receiver has been mung-oiled by means of a float and a spring in dependence onttho quantity, of liquid in the receiver. In accordance with my invention I employ? a spring loaded lift valve for this purpose.

The invention is illustrated in the accompanying drawing in which Fig. l is a vertical section of one embodiment of the invention matically the outletfrom the receiver to the evaporator in such manner that an accumulation of liquefied gas may at all times during satisfactory Working he retained in the vessel. Fig, 2 shows another embodiment in which a host of displacement or solid type is arranged to assist inregulating automatically the inlet valve to the receiver for the some urpose While Fig. 3 shows a further emh'ociment having a float of open top can type arranged to assist in reguleting the inlet of gas from the condenser to the receiver.,

Throughout the several viewsv the same reference numerals indicate-similar parts.

With referehce to Fig. 1 in which A ilenotes the receiver arranged as a. multiple cfi'ect compression receiver, 1 denotes the gas inlet passage to the receiver fromthe condenser; 2 the gas outlet from the receiver loading to the multiple effect compressor; and 3 the outlet passage for liquefied. gas from the receiver to the low pressure evaporator; 4c is a valve loaded partly by a spring 5, the loading of th spring being adjustable from outside the receiver by means of a l spindle 6 passing: through a smiling box to block ll forming an abutmentl'or the spring, the valve spindle sliding loosely in the block 11. The valve 4 is also loaded by /a float 7 Within the chamber it. said float being adopted to rise and fell within the chamber and-cooperating with levers 9 each showing the float assisting to regulate auto-- ficrial Ho. 364,479.

pivoted at one end to an extension of thevalve spindle and hearing at the other end or. the float. The valve 4 thus assists to govern not'only th relative pressures in the evaporator and condenser but also the amount of liquid retained in the receiver. l is a valve controlling the inlet of liquefied gas from the condenser, this valve being adusteble by h nd by means of the usual block 11 whicn is moved by the spindle 6 and being shown as loaded by a. spring 5".

let to the receiver from the condenser, the

inlet valve spindle extends through the receiver, the valve being partly controlled by the spring 5' and partly by the float 7 acting through levers 9 supported at their adjacent ends in the receiver and pivoted on acollar on the valve spindle the regulation of the liquefied gas to the evaporatorfbeing effected or controlled by the valve l which is adjustahle by hand and if desired is loaded by a. spring. l'n the-embodiment illustrated in Fig. 3, showing another arrangement for,regulating the flow of gas from the condenser to l the receiver by automatically controlling the inlet to the receiver from the condenser and employing an open top can type of float, s, pipe 10 dipping into the liquid in the float leads the liquid to the outlet to the evaporator. In this arrangement the levers 9 are connected at their outer ends to links '9' attached to the float 7 and are pivoted adjacent to their inner ends to the receiver, their inner eudsengaging the inlet valve spindle. in this instance also the regulation of flow of the liquefied gas to the evaporator is cflccted by a hand controlled valve 4- which is preferablylooded by a. spring It will he noted that in the three different constructions shown the gas inlet end outlet passages and 2 are located at the upper part of the receive! and that in Figs. 1 and 2 the outlet 3 for the liquefied gas 18 located at the lower part of the receiver,
