DEVICE CRO ELIMINATE VIBRATIONS DURING 'ROTATION OF CRANK-SHAFTS IN PISTON-ENGINES WITH MULTIPLE CYLINDERS.
Specification of Letters Patent.
Application filed September 4, 1920. .seria no. 408,375.
To all whom it may concern:
Be it known that I, Dr. HANS TECHEL, residing at Kiel, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Devices'to Eliminate Vibrations During Rotation of Crank-Shafts in Piston-Engines with Multiple Cylinders, of which the following is a specification.-
' Multiple cylinder piston engines, and
more particularly internalcombustion engines, used for ships drift, all possess the disadvantage that vibrations of the :crank shafts occur during certain speed, which give rise to unsteady running and fracture. The object of the present invention is now to eliminate this disadvantage, and the object is attained mainly by supplying a freemoving body, supported by springs, in -a casing filled with fluid and rigidly connected with the crank shaft; the relative.
movement between the casing and the mov ing vbody being adjusted by means of a throttling device. I
In the accompanying drawing is one embodiment of the invention illustrated.
Figure 1 shows a vertical cross-section of the device, and
Fig. thereof.
the tendency to turn uniformly during the running. This oscillating ring is surrounded by a casing B, that is rigidlypconnected with the crank shaft and closed tightly by a cover'B'. The oscillating ring A and the casing B are provided with claws a and b, which mesh; in the manner ofa claw coupling. Between the claws is,however, enough play provided that spaces-C are formed, wherein helical compression springs D are inserted, one end of which abuts against a claw a of the oscillating ring, and the other end against the claw b of the casing.
The spaces which are to be found between the casing B aild the oscillating ring A are completely filled with a fluid, preferably oil.
The two spaces C, situated one on each side of a claw b, are connected with each other 01 less, flu'id'to pass f from one space C to 1 spaces in the casing h, k of the crank shaft pass from one space to another.
2 a vertical longitudinal section another. The passin of the fluid to the 1? takes place continuously', from the pressure conduit J of a pump (not shown), throiwh the passages II, and ports a and assages a at, a in the oscillating ring Patented ov. 1920.-
In order that the fluid Which has entered the spaces may not runback and counteract on the pump, back-pressure valves F are inserted in the exit passages a. Lastly, exit ports G, with small, adjustable orifices, are provided in the casing and from which small part of the fluid may run out continuously.
When vibrations, caused by the rotation, occur in the crank shaft H, the casing B must partake in these, because it is rigidly connected with the crank shaft. The oscillating ring A, however, tries .to retain its uniform angular velocity. It is, however, prevented from doing this in the same degree as the fluid compressed in the spaces. C is restrained, by the throttle valve E, to
If, for instance, the throttle valve E should be closed tightly and all air driven out, and as the fluid is now compressible, the oscillating ringA must partake in the revolving vibrations of the casing and the entire shaft system. -The loose oscillating ring isconsequently to be considered as coupled with the shaft.
Should, on the'other hand, the throttle -valve E be fully open then the oscillating rin will be able to retain its uniform ve locity almost completely; and a relative movement will take place between the loose oscillating ring 3 and the shaft which is rigidly connected with the'casing, whereby a certain quantity-of fluid will be compressed into one space from another. The magnitude of this relative movementpf the loose oscillating ring and the fixed casing is limited, in this case, only through the inserted springs becauseno throttling of the fluid occurs. 'l function, namely, at alltimes to return the oscillating ring to its central position.
With a determined magnitude of the largest oscillations, and by a thereto corresponding adjustment of the throttling valves E, it is possible to create'a certain resistance against the revolving vibrations, so that the vibrations are quenched or eliminated before he springs have'stillanother they have hadtime to develop completely. In this manner is attained the object of diminishing the stresses of the oscillating system. w
The device is distinguished by its simple construction, its easy adjustment, and the facility with which it may be applied as an 2. In a multiple-cylinder piston engine" having a fluid containing casing rigidly mounted on a crank shaft, an oscillating member concentrically mounted in said casing, and flexible connections between said casing and said oscillating member; said connections comprising alternating projections on said casing and said oscillating member, and springs inserted between said projections.
3. In a multiple-cylinder piston engine having a fluid containing casing rigidly mounted on a crank shaft, an oscillating member concentrically mounted in said casing, and flexible connections between said casmg and sald osc-lllatlng member; said connections comprlsing alternating pro ections on said casing and said oscillating member, and springs inserted between said projections; an adjustable throttle valve for regulating the flow of fluid from one side of said projections to the other.
