GOVERNING CONTRIVANCE FOR JET-IMPELLED WATER-MOTORS.
Specification of Letters Patent.
Patented May 30, 1911.
Application filed May a, 1910. Serial No. 559,117.
To all whom it may concern:
Be it known that I, JENS ORTEN-BOVING, subject of the Kin of Sweden, residing at 9% Union Court, 61d Broad street, in the city of London, England, have invented new and useful Improvements in Governing Contrivances for Jet-Impelled WVater-Motors, of Which the following is a specification.
This invention relates to improvements in governors employed to regulate the supply of water to jet-impelled motors, which governors are of the type in which, when a reduction of speed or power is required, the
first operation performed is to divert a portion of the issuing jet of water, this action being followed by a diminution of the section of the jet at a rate sufliciently gradual to avoid an undue increment of pressure in the water-supply pipe which is caused by the change of momentum of the flowing mass of water contained Within the pipe, the second effect being caused by the operation of what will be described as an interceptor.
In the accompanying drawing is shown, as a representative example, a form of construction embodying the invention the nature of which is above described.
In this drawing :Figure 1 is a part sectional elevation, and :Fig. 2 is a transverse view of a detail.
In Fig. 1 a represents a Pelton or other kind of water-wheel which is driven by a jet of water conveyed by a pipe 0 and delivered through a nozzle (Z, the area of discharge through which is regulated by a pointed valve e whose axis coincides with those of the nozzle and jet.
The contour of the nozzle and valve are such as to direct a stream of annular section to converge into a cylindrical jet the diameter of which diminishes as the valve is moved from right to left and so constricts the area ofdischarge and diminishes the power de veloped.
The diminution of power by a reduction in the quantity of water delivered through the nozzle must be effected very slowly or a dangerous pressure will occur in the supply pipe by the abrupt arrest of the momentum of the moving mass of water in what may be a very long supply pipe, and yet, when the load or work to be performed lessens, and often quite suddenly, it is requisite that the power exerted should be correspondingly diminished in a very prompt manner to prevent the wheel and the machinery driven thereby from acquiring an injurious speed. This is effected by interposing in a portion of the section of the jet a deflector P which is pivotally mounted on the spindle a of the Water-wheel or other appropriately situated pivot, thereby diverting a portion of the stream and preventing it from impinging on the blades of the wheel.
The interposition of the deflector is effected by some form. of governor, not shown, which operates on the spindle g and angularly displaces it anti-clockwise as the speed of revolution increases, the movement of the spindle being transmitted to the deflector f by a lever keyed to the spindle and connecting rod 9 The displacement of the governor-spindle 9 also causes, by means of a second lever k and connecting rod h a piston h to be thrust away from the left end of a cylinder 70 against the pressure of fluid which is admitted to the cylinder through a flexible pipe connected to the orifice 70 Normally, the piston It will be retained at the left end of the cylinder by the fluid pressure within the cylinder it, but when an increase of speed occurs the piston will move away from the left end of the cylinder and eject some of the fluid. The cylinder is constitutes a hollow plunger of a fixed cylinder m and the fluid pressure within 70 will persistently tend to replace the piston 71 to the left end, by causing the cylinder 7: to move to the right. Now the space within the fixed cylinder at not occupied by the plunger-cylinder 7:, is filled with a viscous liquid such as oil, and this space is placed in communication with a reservoir 72 by a passage 0 which can be throttled to any desired degree by an adjustable valve 0 On account of the passage 0, the liquid in at will leak into the reservoir a when a pressure is applied to force the plunger-cylinder is to the right but, by regulating the constriction 0 the rate of displacement of the plunger-cylinder can be made as slow as may be desired. When by the movement of the cylinder 70 to the right the piston it again occupies the left end of the cylinder, further progress of the plunger-cylinder will be arrested because then the fluid-pressure on the cylinder-end will be balanced by the equal and opposite pressure on the piston It.
By means of a piston-rod 1), link 9, lever r and link 8, the slow movement of the plunger-cylinder 7c is communicated to the before-mentioned intercepting valve 6 the position of the deflector f and the position of the intercepter e to be definitely related to each other and both dependent on the position assumed by a single governor.
The ratios of the interposed levers are so proportioned that in all positions, when the lost motion has been recovered, the deflector will stand clear of the et with a minimum interval so as to be in position to effect a further reduction of power with the least displacement of the governor and delay. In
Fig. 2, which shows the deflector and the section of the jet of water on an enlarged scale, the large circle 6 drawn with a full line, is intended to represent the diameter of the jet when. the valve 6 is fully open, the simultaneous position of the deflector being represented in full lines by P. When the valve is partially closed, the smaller dashdotcircle b shows the section of the jet and the corresponding position of the deflector is shown in dash-dot lines by F.
Connecting the cylinder m and the reservoir n is an additional passage commanded by a valve t which closes when the plungercylinder 70 moves to the right but opens to permit the free back-flow of liquid from the reservoir, when it moves to the left. Accordingly, when increase of power is required, there will be no constraint against the prompt opening of the intercepting valve, the deflector being simultaneously proportionately moved so as to avoid interference with the stream which attains an enlarged section.
