An Apparatus for Governing the Valve Gear of Hydrocarbon
Motors.
I, ROBERT CONRAD of 6, Lackierergasse. Vienna in the Empire of Austria,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
This invention relates to a governor which is intended more particularly for
application to hydrocarbon motors and the like engines, and which governs the
said motors by throttling the supply of motive fluid. A governor of this kind is
illustrated by way of example in the accompanying drawings. In the arrange-
ment shown there is employed the cooling water of the motor, which is forced by
means of a pump or other propelling device through the cooling jacket of a gas
engine of any suitable construction, but the governor may also be employed with
other motors which do not require.cooling water. In such cases the water is taken
from any convenient source.
The following is an explanation of the invention with reference to the drawings
in which a indicates in a diagrammatic manner a gas engine of any suitable con-
struction. Upon the crank shaft 6 of this engine there is mounted a centrifugal
pump e; but this latter may be omitted and in its stead there may be employed
This
any other water-delivering apparatus capable of being driven by the motor.
pump e draws water through the pipe d and delivers the said water through the
pipe e into the cooling jacket f of the motor. From this space the water flows out
again at the highest point at g, and flows away through the pipe h. The mouth of
the pipe is situated over a vessel k which is suspended from a two-armed lever i i.
In the bottom of the vessel k there is provided a small valve / which has a sensitive
regulating device and a small cross sectional area of flow, a needle valve for
instance. Further the vessel k is provided with an overflow pipe m. The outlet
openings of the valve land of the small pipe m are arranged over a discharge
pipe n. The two-armed lever i ¹ is pivotted or fulcrumed in the axis of the plug
of a cock o which is inserted in the pipe ppl that serves to supply the hydrocarbon
or other motive fluid. Then, by moving the two-armed lever ii, the supply of
motive fluid to the motor will be modified, and consequently the motor will be
governed thereby. A spring 9 which can be adjusted by means of a screw r serves
to balance the lever mechanism i i¹ in equilibrium.
So long as the motor runs uniformly, the water delivered by the forcing device c
through the cooling jacket f flows into the vessel k and flows out of the said vessel
again through the valve 1. But if the number of revolutions of the motor
increases, then as the output or delivery of the forcing device is also increased
thereby more water will flow into the vessel k than can escape uniformly through
the valve l. In consequence, the vessel k will gradually become filled, and the
excess of weight. thereby produced will overcome the opposition of the spring g
and act to rotate the cock o so that the flow of motive fluid is diminished and thus
the motor is caused to run more slowly. When the number of revolutions falls
again to the normal rate, the vessel k will become lighter, in consequence of the
quantity of water that has run off in the meantime, whilst fresh water runs in
only in a moderate degree, so that the flow of motive fluid is again left unimpeded.
The overflow pipe m serves to prevent the vessel k from running over. The

page_text: governor herein described has great sensitiveness which is capable of great accuracy
of adjustment, in consequence of the easy adjustability of the spring g and of the
cross sectional area of How through the valve 1. It has the further advantage
that the motor is cooled in an increased degree proportionate to the increase in the
speed of the motor.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
(1.) The improved governing apparatus for hydrocarbon motors, substantially
as herein before described and illustrated by the accompanying drawings.
(2.) An apparatus for governing the valve gear of hydrocarbon motors con-
sisting essentially of a pumping device driven by the motor and adapted to force
water through the cooling jacket of the motor, and of a device for controlling
the valve supplying the hydrocarbon consisting essentially of a two armed lever
fixed to the spindle of the valve, of a vessel suspended from one end of the said
lever, the said vessel being provided with a suitable outlet valve and of a spring
adapted to balance the said vessel through the medium of the two armed lever, as
set forth.
