ATENT ADOLPHE CLEMENT, OF vALLoIs-PERRET, FRANCE.
REGULATOR FOR SUCTION VALVES OF EXPLOSlVE-ENGINES.
' SPECIFICATION forming part of Letters Patent No. 732,830, dated July 7, 1903.
Application filedbctober 9,1902. Serial No. 126,382. (No model.)
To all whom it may concern:
Be it known that I, ADOLPHE CLEMENT, a citizen of the Republic of France, residing in Levallois-Perret, Seine,France, have invented certain new and useful Improvements in Regulators for Suction -Valves of Explosive Engines, of which the following is a specification.
In all petrol-motors the suction-valves open automatically every second revolution owing to the vacuum produced within the cylinder during the descent of the piston. This arrangement is advantageous because of its simplicity; but it presents the defect that the counter-springs must necessarilybe very.
side of the cylinder, thus necessitating the use of another cam shaft. These two arrangements, which are the only ones which have hitherto been employed, present the defeet of considerably-increasing the volume of the conduit upon the compression-chamber or of creating a fresh one upon the other side of the cylinder. In either case the volume of the compression-chamber situated directly above the piston is decreased by this amount, and the utilization of the explosive force of the mixture is consequently reduced, this explosion taking place to a great extent in the lateral conduit or conduits. Obviously, therefore, it is of importance to diminish the size of these conduits as much as possible. In accordance with my invention this result is attained by retaining the automatically-operated suction-valve in the position which it occupies in motors in which it is automaticthat is to say, directly above the exhaustvalve.
The improved arrangement is illustrated is no larger than it would be if it only served to conduct the burned gases to the exhaust valve H. In addition to this only one shaft is employed for the suction-cams B and the exhaust-cams I. With this arrangement I have combined a mechanism permitting, either by hand or governor adjustment or by both in combination, of imparting variable lifts to the suction-valve from zero up .to the maximum rise provided for. In order to efiect this, the cam B presses by the intermediary of appropriate parts beneath a lever K, pivoted at L,
and of which the radius of curvature is equal to the length of the rod 0. A rod M, operated either by hand or automatically by the governor or by both means in combination, is capable of displacing the point of support of the rod or rods 0 upon the lever K. According as this point of support is above orin more or less close proximity to the point L the suction-valve will not rise or will rise to a greater or less extent. In this manner a regulation of the speed and power of the motor is obtained in an extremely simple manner, because within a certain limit the varying lifts of the suction-valve correspond to the different powers of the motor and no explosion will be produced when the rod 0 is at the point L, because the suction-spring is sufiici-ently strong to prevent the suctionvalve from opening automatically.
I claim as my invention- 1. In a petroleum-motor, the combination of a suction-valve, a cam for operating the same, a substantially horizontal lever L arranged to receive motion from said cam, a vertical rod 0 resting at its lower end on said lever L, a lever D bearing against the stem of said valve and pivotally connected to the upper end of said rod 0, and means for mov- L so that it rests on said lever at different distances from the pivotal point and thus varies the lift of the rod and the opening of the valve.
2. In a petroleum-motor, the combination with asuction-valve of a cam for operating the same, a substantially horizontal lever L arranged to receive motion from said cam, a substantially vertical rod 0 resting at its lower end on said lever L, a lever D bearing on the stem of said valve and pivoted to the upper end of said rod 0, means formoving the lower end of said rod on said lever to
