Description
June 29, 1948. M. MALLORY ENGINE GOVERNOR Filed March 22 1945 I INVENTOR. Mar/0n Mafia/y Patented June 29, 1948 ENGINE GOVERNOR p .Marion Mallory, Detroit, Mich. Application March 22, 194 5,-Serial No. 584,055
7 -1 "This invention relates to 'a' governor for controlling the speed of an internal combustion engme.
It is the object of this invention to produce a governor for controlling the speed of an internal combustion engine which is eflicient in operation and relatively simple in structure.
The drawing is an elevation partly in section showing my engine speed governor.
The parts of my engine governor are referenced as follows: governor housing I having an inlet2, an outlet 3, unbalanced governor valve 4 mounted on valve shaft 5, arm 6 fixed on shaft 5, spring I tending to hold unbalanced valve 4 open, flexible diaphragm 8, rod 9 operatively connecting diaphragm 8 with arm 6, pressure chamber H], conduit l I communicating with valve housing l2, hydraulic pressure line I3 which is connected into the engine oil pump pressure line (not shown), valve I4 having a circumferential groove [5, centrifugal governor l6 which is rotated or driven by a governor shaft I! which is driven by the engine being governed, governor tension spring is which tends to collapse the governor.
The operation of my device is as follows: Valve 4 is preferably a velocity type governor valve, that is, the valve is unbalanced with the greater portion of the area of valve 4 above shaft 5, as viewed in the drawings, so that the velocity of the motive fluid flowing through the intake passageway and the engine intake manifold suction will tend to close valve 4 against the tension of spring I which tends to hold the valve open. If the engine is to be governed at, say, 2800 R. P. M., the centrifugal governor IE will hold valve I4 in the position shown until the engine reaches 2800 R. P. M. In such position, naturally, the oil pressure taken from the oil pump through pressure line 13 will be admitted through groove l and line H into pressure chamber N). This oil pressure will act 4 Qlaims. (01. 123-99 point is that when the engine reaches its governed through diaphragm 8, rod -9 and arm 6 to hold valve 4 toward an open position. When governor I6 is expanded at a predetermined engine speed or the governed speed of the engine, say, for example, 2800 R. P. M., valve l4 will move upwardly closing ofi orifice [9, that is, pressure line I3, and the piston valve l4 will move out of the upper end of valve cylinder l2 so that the circumferential groove I5 places line H in communication with the crankcase or inlet side of the oil pump (not shown), thereby relieving the pressure on the diaphragm 8. The oil pump will run in accordance with the speed of the engine so that the oil pressure in line l3 will vary in accordance with the speed of the engine. However, the important speed, the centrifugal governor 16 moves valve 14' upwardly so that it bleeds liquid out of pressure chamber l0 and thereby relieves the pressure in the chamber. Spring 1 will then be opposing the closing of valve 4 and since valve 4 is slightly unbalanced, the velocity of the fluid flow through the intake passageway and the vacuum on the outlet side of valve 4 will tend to close it, checking the speed of the engine, but any time the speed of the engine falls slightly, governor IE will shift valve [4 downwardly and cause communication between the oil pressure line I3 and the pressure chamber in so that the oil under pressure acts through diaphragm 8 and arm 9 to assist spring l to open governor valve 4.
The subject matter of this application is disclosed in my patent 2,356,679, issued August 22, 1944.
I claim:
1. A governor for an internal combustion engine comprising an unbalanced valve positioned in the intake passageway for controlling the flow of motive fluid through the passageway and normally actuated toward closed position by the velocity of the motive fluid flowing through said intake passageway, yielding means opposing movement of said unbalanced valve toward closed position, and hydraulic pressure actuated means acting on said valve and tending to keep the same open, and liquid bleed means controlled in accordance with the speed of the engine for bleeding said hydraulic pressure operated means whenever the speed of the engine substantially reaches its governed speed whereby said valve moves toward closed position.
2. A governor for an internal combustion engine comprising a valve positioned in the intake passageway for controlling the flow of motive fluid therethrough, means tending to close said valve as the engine approaches its governed speed, resilient means tending to move said valve toward open position, hydraulic pressure operated means opposing the closin of said valve, and a centrifugally controlled liquid bleed for said pressure operated means controlled in accordance with the speed of the engine for bleeding liquid from said pressure means whenever the engine is running substantially at its governed speed whereby the pressure in said pressure means is relieved and the governor valve moves toward closed position.
3. A governor for an internal combustion engine comprising a valve positioned in the intake passageway for controlling the flow of motive fluid therethrough, fluid pressure actuated means 3 responding to an increase in the velocity of the fluid flow through said intake passageway as the engine approaches its governed speed and tending to close said governor valve, resilient means tending to move said valve toward open position, hydraulic pressure operated means. opposing the closing of said valve, and a centrifugally controlled liquid bleed for said ressure operated means controlled in accordance with the speed of the engine for bleeding liquid from said pressure means whenever the engine is running substantially at its governed speed whereby the pressure in said pressure means is relieved and the governor valve moves toward closed position.
4. A governor for an internal combustion engine having an intake passageway comprising an unbalanced throttle valve positioned in the said intake passageway for controlling the flow of motive fluid therethrough, and responsive to changes in the velocity of the motive fluid flowing through said passageway, hydraulic pressure actuated means having an operative connection with said REFERENCES CITED The following references are of file of this patent:
