PATENT OFFICE.

The engine is stationary, the cylinders are open at the top.

The motor consists of the frame A ,. in the lower part of which the working cylinder B and compression cylinder C are cast. The single cranked crankshaft D is mounted in the upper part of the frame. The working piston F is connected to the crankshaft D by means of a connecting rod α. The pump piston G is coupled to the connecting rod a by connecting rod b.

The air and gas inlet valve 0 is automatic, as is the check valve L. The slide respectively. the ignition device is moved by handlebar d and crank e ; which latter is combined with the drive wheel of the regulator. The ignition device itself is that described in patent specification no. 7212 described.

The discharge valve P is controlled by the fabric eccentric k, rod Z and thumb m .

The regulation is effected by regulator K, lever g, handlebar -h and lever i .

During upward passage of the pump piston G drawn in through the in Fig. 5 on an enlarged self-active Mafsstabe valve ο air and gas as shown in, in such circumstances, the mixture in the highest degree DAF is explosive. When the piston G returns, it presses the explosive mixture through the automatic check valve L into the working cylinder. When both pistons have come to half of their decline, the outflow valve P shown in Fig. 2 closes and both pistons now jointly compress the explosive mixture, whereby it is simultaneously pushed completely out of the pump cylinder and over to the working cylinder. From the arrangement of FIG. 1 it can be seen that the pump piston leads the working piston. It follows from this that the automatic check valve is already closed when the working piston has reached its dead point and before the explosion occurs. As soon as the working piston has reached the dead point below, the ignition device shown in FIGS. 2, 3 and 4 mediates the ignition of the explosive mixture in the working cylinder. The resulting expansive force drives the piston F upwards, which transfers this work to the crank D. During this upward gear, the piston G has again drawn in new mixture. When the crank D has reached its highest point, the outlet valve P opens and part of the burnt gases is driven into the open when the piston F descends.

The outlet valve closes when the working piston has finished about half of its low flow. From this it follows that a large quantity of the residues resulting from the previous combustion must remain in the working cylinder. These residues are BEZW during the compression. when the explosive mixture crosses into the cavity of the piston F , they cannot mix with the freshly entering explosive mixture. Rather, the latter remains, caused by the inclined arrangement of the inlet channel, on the cylinder base. The freshly entered mixture therefore burns momentarily even when it ignites, while the residues in the cavity of the piston act as momentary heat consumption.

serve, which in turn give off operating power through expansion. The machine is regulated by pressing the small valve η shown in Fig. 5 onto its seat by means of the regulator K, lever ^, rod h and lever i, whereby the gas flow is shut off and the pump consequently only air can suck in. There are therefore no explosions as long as the machine runs beyond its normal speed. . The type of mutually inclined arrangement of the two cylinders and the coupling of the connecting rods on a crank, so that the pump piston leads the working piston, ensures that the automatic check valve closes and functions reliably and that the explosion can occur if the The working piston is down at the dead point, which eliminates the bumps that are otherwise noticeable in vertical engines. Motors of similar construction suffer from irregularities caused by the ignition, in that both pistons were at the dead point at the same time, in that if the non-return valve was not shut off safely, the explosion often continued to propagate to the pump cylinder, which also caused very violent jolts in the machine became. Another disadvantage with the check valve itself was the frequent soiling of it. The pump forces lubricating oil to the non-return valve, which, since the "mixture stored there is always burnt above the valve seat, builds up as a solid crust in the upper valve housing. This also creates irregularities and requires more frequent cleaning". This deficiency is eliminated by the arrangement in Fig. 6. The upper housing of the check valve is surrounded by a special jacket made of wire mesh, which prevents the flame from breaking through when ignited, as a result of which the oil inside the jacket does not burn and does not form a solid crust can start. In the case of self-acting gas and air inlet valves, heretofore, the valves have either been double-seated or arranged separately. The latter are complicated, and the former give rise to great irregularities during operation, since leaks arise very soon because of the two sealing surfaces. This cannot occur with the air and gas inlet valve illustrated by FIG. In the case of the valve in question, the outer conical is the main sealing surface. The gas is supplied through a cylindrical extension of the valve o, which also serves as a guide for the same. The extension of the valve is pierced at the top by openings from which the gas can exit when the valve is lifted by sucking in the piston and can mix intimately with the air flowing in at the same time. If the valve is pressed onto its seat surface during compression, the gas is sealed off by the cylindrical sealing surface. This arrangement ensures that the gas is adequately shut off during the operation of the engine, and the combination of the conical sealing surfaces with the cylindrical one is self-sufficient, so that the valve must always function well. and not like other double-seated valves give rise to frequent irregularities by leaking one or the other sealing surface. In gas engines, the regulation of which was effected only by a regulating valve switched on in the gas supply, the unfavorable arrangement of this valve resulted in a disproportionately high gas consumption as soon as the engines stopped. to their full strength. This inconvenience was due to the fact that the regulating valve was arranged in such a way that when the piston was sucked in the valve was always lifted and a quantity of gas was sucked in, which, since it was insufficient to produce an explosive mixture, passed through the machine unburned. In the arrangement of FIG. 5, this disadvantage is eliminated. If the regulator presses the regulating valve 11 on its seat surface when the engine is running too fast, the valve; z is only pressed more firmly onto its seat surface by sucking in the pump piston and any loss of gas with less power is made impossible. Pa τ en τ-An Proverbs: 1. The arrangement of an automatic gas and air inlet valve ο in such a way that the valve cone serves to seal off the sucked in air and gas mixture, and the lower cylindrical extension of the valve with holes at the top both for sealing off the sucked in gas and for valve guidance serves. 2. The arrangement of a gas inlet regulating valve in such a way that the same in the regulator unaffected state is always open when the regulator acts not only pressed on the same, but an even tighter pressure when the engine piston is sucked in the same is effected on the valve seat, so closing off the gas supply line.
