As the pressure acting on surface 53 of r 54 around the piston and acting on the opposite Referring to Fig. 2, the control valve consists during the expansion stroke, the pressurein conmember operating against a valve seat 21 and pressure on surface 53 of the piston 31 and per- 4 held against an abutment 28 by means of spring l mitting valve 38 to be held firmly against seat 21 29. The valve 23 is forced towards its seat 2"! during the exhaust stroke. When the steam in ment 28. A screw 3| and a nut 32areprovided sure in cylinder l8, oil previously injected around a diaphragm 34. The diaphragm 34 is held in In order to assure immediate discharge of oil Apiston 31 is provided with a valve extension has been discharged into chamber 52, an atomiz- 33 and is urged towards valve seat 21 by means ing steam nozzle 4| hasbeenprovided. Steam,
Asteam nozzle 4| is screwed into adapter 42 55 20, conducted through pipe 2| enters connection and is discharged at high velocity through the I T atomizing nozzle 4|. The boiler pressure being at through the steam nozzle M is not sufi'zlcient to increase the pressure in chamber 52 to any measurable degree and the steam entering from said nozzle does not in any way'affect the pressure fluctuations in chamber 52. Only a sufiicient amount of steam enters through said steam nozzle to assure immediate dischargeof oil into the V passage 5t and hence to the steam cylinder 18. e In this manner, oil will have been discharged from chamber 52 into steam cylinder l8 during the high pressure interval, and the oil discharge will be completed before the end of the expansion stroke and the beginning'of the exhaust stroke of the piston Na, and thus no oil will be discharged into the cylinder during the exhaust part of the stroke. 7 During the exhaust part of the stroke extension .38 of piston 31 is held firmly against seat 21 Qclosing passage 49. At this time'the'tension of spring 39 issupplemented by the pressure onthe spring side of piston 37, which pressure entered around the clearancev space 54 during the maximum pressure period as explained above.
It will be understood that, when the locomotive drifting and no steam used in the cylinders, the oil pressure in passage 49 acting on the surface 50 of valve 38 will open valve 38 againstspring 39 without the aid of steam pressure.
-; It is furthermore apparent'that if the valve member 26 is opened while valve 38 is held to'its seat, the valve member 26 will remain open until .;valve 38 opens and relieves the pressure, at which time valve member ZSwill be'seated, as the pressure drops in the oil space below diaphragm 34. W-hile I have explained the operation of the oil -control valve in connection witha steam engine,
it is obvious that the same valve may be used with .an air, engine,- infact any type of engine in which the cylinder pressure is subject .to periodic fluctuations, v p It is understood that various changes in form,
e p r 2,329,040 122 and passage 46, lifts ball check 43 from its seat proportions and minor details of construction may be resorted to without departing from the principles or sacrificing any of the advantages of the invention as defined in the appended claims,
What I claim as new, is: 1. An oil control valve having an inlet for oil under pressure, a primary chamber having a valved outlet, a secondary chamber having a valved inlet in communication with said valved 1 outlet and a main outlet to the cylinder of an engine, and means in said secondary chamber to open momentarily said valved inlet during the pressurestroke in said cylinder and to keep said valved inlet closed during the exhaust stroke in said cylinder.
2. An oil control valve having an inlet for oil under pressure, a primary chamber having a valved outlet, a secondary chamber having a valved inlet in communication with said valved outlet and a main outlet to the cylinder of an engine, means in said secondary chamber to open momentarily said valved inlet during the pressure stroke in said cylinder and to keep said valved inlet closed during the exhaust stroke in said cylinder, and anatomizing jet dischargingv into said secondary chamber to accelerate the ejection of oil from said secondary chamber.
3. An oil control valve having an inlet foroil under pressure, a primary chamber having a valved. outlet, a secondary chamber having an inlet port in communication with said valved outlet and a main outlet to the cylinder of an engine,
and a pistonin said secondary chamber having means to close said inlet port, said piston being adapted to open momentarily said inlet port during the pressure stroke in said cylinder and to keep said inlet port closed during the exhaus stroke in said cylinder. v
