Be it known that I, CHARLES HENRY NAYLOR, a subject of the King of Great Britain, residing at Rugby, in the county "bines and more particularly to turbines vofi,lVarwickshire, England, electrical eninecr,have. invented certain new and useul Improvements in and Relating to ElasticfFluid Turbines, of which the following is a specification. i
This invention relates to elastic fluid turwhich rare utilized to drive. a rotary condenser operatin in conjunction with a prime mover suc asa reciprocating engine capable of working efficiently with a va-cuiirifi`r cient quantity or the pressure of the exhaust Ina be too low to drive the turbine. he object of my invention is to construct an improved turbine of this type.
For a consideration of what I believe to be novel and my invention, attention is directedto the accompanying description and the claims appended thereto.
Figure 1 is a vertical section through a turbine illustrating one of the embodiments of my invention, and Fig. .2 is a diagrammatic view showing a reciprocating engine and turbine installation.
In carrying my invention into eifect according to the modication illustrated in the accompanying drawing, I provide fi mixed pressure turbine the rotor 1 of which may bofinounted on the shaft 2 carrying the impeller 3 of the rotary condenser. The specific Istructure ot' the condenser forms no part of the present invention and may be of an'y suitable construction. The inlet nozzles 4f for the low pressure steam extend practically completely around the periphA ery with the exception of a small space within which are inclosed one or two nozzles 5 adapted to'receive steam from a high pressure source of supply. With the exception of these one or two nozzles the remainder of the nozzles are situated in an annular space 6 into which the exhaust from the prime mover'is discharged through the conduit 7. The rotor of the turbine consists of a spider 8 having an annular outer cured. Mounted in the space inclosing the high pressure inlet nozzles is a high pressure steam conduit controlled by a valve i. This valve is held on its seat by means of a spring 12 and opened by means of u spindle l'. controlled by the governor' 14 acting against the spring. v Mounted on the spindle which operates the high pressure valve is ahy-pass valve 15 which. controls an aperture through which the low pressure steam Amay pass to an annular chamber 1t one side of which is bounded by the rotor of the turbine so that steam entering the through between the arms of the rotor andl so to the condenser without passingl through the turbine blade. The by-pass valve is operated by the speed governor 14 in such a manner that as the speed of the turbine rises above a predetermined point the valve Opens and allows some of the low pressure steam to pass to the condenser without doing work on the turbine blades. If, on the other hand, the supply of low pressiire steamis insufficient to -keep the speed up to the required point the spindle 13 of the by-pass valve is moved so as to cause the Khigh pressure valve 12 to open and admit live steam to the few nozzles controlled by said valve. movement of the spindle to open the high pressure valve may cause the by-pass valve 15 to close entirely or may cause it to pass through its closed posi tion so that very little of the low pressure steam need pass through the turbine bla@ s While the turbine is being supplied. with high pressure steam. .In rig'. the turbon condenser is illustrated as being connected to the exhaust conduit 3l of a liigli pressure reciprocating engine 30.A
I do not wish to limit myself to any par-r ticular construction of valves or governing 'inechanismy as it will be Obvious that the construction may be varied considerably without departing from the spirit of my invention.
What I claim as new and 'esire to secure by Letters Patent oi the United States is 1. In a` turbine, the combination of a casing, a supply conduit, a vbladed rotor in the casing aving a fluid conveying passage thatis independent of and shunts the blades,
flcvices for discharging fluid against the -rirn 9 to which the moving blades are srchamber through the valve 15 may pass tion and open again inthe opposite direcv il;
icc
\ controlled 'conduit or shunting motive fluid 4conveying passage located between its shaft and blades, devices for discharging low pres- -engine and a casin containing a rotary consure motive fluid a ainst the blades, a valve around Asaid blades and devices and into the p'aage of the rotor, and means for admitting motivefiuid to the rotor froma 'separate sourceiwhen the Iirst named supply is deficient. o
` 3. The combination with a high pressure denser therefor, o a bla-ded rotor therein to which the low pressure steam is freely admitted on its way to the condenser, a by, pass in the casing around the rotor for permitting low pressure steam to pass directly to the condenser without acting on the rotor,"
valve means controlljuig it, an inlet for supplying high pressure 'steam :to the turbine rotor, controlling valve means therefor, and a governor controlling both the valve-means aforesaid so thatwhen the ysupply of lowv pressure steam becomes excessive it is bypassed to the condenser and so that when said supply is insufcient high pressure steam is admitted.
.4. The combination with a high pressureengine and a casing containing a rotary condenser therefor, of a turbine rotor mounted in thel casing for driving the condenser, means for directing .the exhaust -from the engine to the rotor, a by-pass which shunts the directing means, a valve controlling said, 40 Icy-pass, and means for opening said valve to shunt any excess of exhaust steamabove that required to drive the turbine rotor, directly to the condenser.
In witness whereof, I have hereunto set my hand this tenth day of June 1913.
