I REGULATING DEVICE FOR EXPLOSION-MOTORS.

SPECIFICATION forming part of Letters Patent No. 781,160, dated January 31, 1905. Application iiled October 1'7, 1903. Serial No. 177,442.

T ctZZ whim@ it may concern,.-

Be it known that I, KARL REINHARDT, a subject of the Kingof Prussia, German Emperor, and a resident of 36 Arndtstrasse, Dortmund, in the Province of Westphalia, German Empire, have invented a new and useful Regulating Device for Explosion-Motors, of which the following is an exact specification.

My invention relates to a regulating device for explosion-motors, and more especiallyT to a device for regulating the movement of the inlet-valve; and it has for its `purpose to provide a mechanism by means of which the stroke of the valve, as well as the time during which the valve is opened, can be regulated without any back pressure upon the governor being exercised. I attain this purpose by arranging a lever for moving thevalve-spindle, the pivot of which lever can be moved by means of a piston situated in a cylinder filled with oil, the quantity of oil in the cylinder being regulated by means of the governor.

In order to make my invention more clear, I refer to the accompanying drawings, in which- Figure l is a vertical section ofthe principal parts of my new construction. Fig. 2 is a detail view of the cylinder filled with oil. Figs. 3 and 4 are horizontal sections of the oil-cylinder and a turnable cylinder situated around the same. Fig. 5 is a modiiication of the construction shown in Figs. 1 to 4.

In the drawings, a is the inlet-valve of an explosion-motor. Y

CZ is the valve-spindle. To the valve-spindle (Z a valve-piston is fixed, by the movement of which the gas and air situated in the channels e and f are allowed to pass into the space above the valve a and from there into the cylinder. The regulating is eected in that way that according to the position of the governor the stroke Vof the valve and of the pistonis enlarged or diminished, thereby more or less throttling the quantity of the explosivegas mixture entering into the cylinder. The stroke of the inlet-valve is regulated, according to the present invention, by adjusting the pivot A of the lever Zi, moving the valve-spindle (Z. The-pivot A is situated at the end of the 4piston-rod s of the piston ZJ. This piston Z: is situated in a cylinder c, filled with oil.

` The cylinder c is provided with slots 0 and with a cover g, through which passes the piston-rod s, a stuiiing-box g being provided for Vpacking the piston-rod. Around the cylinder c a cylinder c is situated, which is provided with corresponding slots 0'. This cylinder c can be turned by means of the governor, thereby more or less opening the slots 0 of the'cylinder c. z' is a lever moved by means of acam Z. The leverz'is connected, by means of the connecting-rod m, to the end B of the lever ZL. At the other end of this lever /L a roller C is provided, which roller is situated upon the valve-spindle d.

F is a spiral spring which tends to close the valve rZ-that is to say, to press the valvespindle cZ upward. The spring F' consequently tends to press the pivot A of the lever /a upward, thereby pressing the oil situatled above the piston Zt through the slots 0 anc 0 If the cylinder c is turned by means ofthe governor, and the openings oare consequently more or less opened, the piston Zt will {ind more 0r less resistance in pressing the oil through the openings, and consequently the pivot A will be more or less raised-thatis to say, the roller C will be pressed more or less downward.

If the rod mI moves downward, the spiral spring F etfects, even in case the pivot A still moves upward, a turning of the lever Z1 around the pivot A, so that not only the quantityoil gas is more or less throttled by the position of the pivot A, but also ythe closing ot' the valve takes place earlier or later. After the valve is closed a spring F2 effects that the roller c" of the lever v.' is always pressed upon the cam Z, thereby pressing the piston kdownward. By the piston 7c being pressed downward the oil situated underneath the piston is pressed through the openings g into the space c3 around the cylinders c and 0^. If the piston Za is in its lowest position, the openings p are open, so that the space above the piston Zt can il'l again with oil.

The modiiication shown in Fig. 5 differs from the construetion'above described by the cylinder c being replaced by a cylinder c2, situated at the side of the cylinder c. The cylinder c2 is also turned by means of the governor and is provided with an inclined slot 02. In the cylinder c a piston moved by means of the lever L, is situated, the lower surface of said piston being inclined. It' the end B of the lever L begins its upward movement, the opening 02 is closed by means of the piston Zig. The oil situated above the piston 7:: can consequently not escape through the openings o and og--that is to say, the pivot A cannot be moved and the inlet-valve will consequently be opened. As soon as by the upward movement of the end B of the lever 7L the piston 772 begins to open the opening 02 the oil situated above the piston 70 can escape. From this moment the pivot A will raise and the inlet-valve will begin to close. After the inlet-valve being closed both pistons move downward again and the cylinders are filled again with oil.

' In both constructions it is attained by the arrangement of the oil cataracts that the stroke of the inlet-valve as well as the time during which the same is opened are regulated by means of the governor without any back pressure upon this governor being exercised.

Having thus fully described the nature of my invention, what I desire to secure by Letters Patent of the United States is- 1. In a regulating device for explosion-motors, the combination of a gas-inlet valve, a valve-piston iiXed to the spindle of said inletvalve, a lever for moving the valve-spindle, a cylinder filled with oil, a piston situated within said cylinder, the lever mentioned above being pivoted in the piston-rod of this piston, openings provided in said oil-cylinder and means for regulating the passing of oil through said openings, substantially as described and for the purpose set forth.

2. In a regulating device for explosion-motors, the combination of a gas-inlet valve, a valve-piston fixed to the spindle of said inletvalve, a lever `for moving the valve-spindle, a cylinder filled with oil, a piston situated within said cylinder, the lever mentioned above being pivoted in the piston-rod of this piston, a second cylinder, openings provided in said second cylinder, and means for regulating the passage of the openings of' said second cylinder, thereby regulating the passing of oil through the openings of the first-mentioned cylinder, substantially as described and for the purpose set forth.

3. In a regulating device for explosion-motors, the combination of a gas-inlet valve, a valve-piston fixed to the spindle of said inletvalve. a lever for moving the valve-spindle, a cylinder filled with oil, a piston situated within said cylinder` the lever mentioned above being pivoted in the piston-rod of this piston, a second cylinder, openings provided in said second cylinder, means for turning the latter thereby regulating the passing of oil through the openings ot' the first-mentioned cylinder, substantially as described and for the purpose set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

KARL REINHARDT.
