IMPERIAL

PATENT OFFICE.

The invention is a control for a motor, which is particularly by Carbon dioxide is to be operated and its essential feature in the arrangement of the Distribution valves and the thumb discs that move them, so that the machine only needs a small amount of space and is used especially for vehicles can.

The drawing represents the new engine and shows:

Fig. Ι a side view of the engine,

Fig. 2 is a top view of the same, partially drawn in section, and

3 shows a detail of the distribution valve.

The motor has two cylinders, a cylinder α for the supply of the pressure medium under full pressure and a cylinder b of larger diameter for the expansion. The pistons a ^l and b ^l move in opposite directions and are connected to the WeWe f by means of a connecting rod, crosshead and crank.

The propellant is supplied through a pipe g which is connected to the two valves M and M ¹ , which in turn are connected to the two ends of the small cylinder α . Another valve N is connected to the front end of the cylinder b , as is the valve iV ¹ on the one hand with the rear part of the cylinder α and on the other hand with the rear part of the cylinder b.

Furthermore, the valve P communicates with the rear part of the cylinder b and with an outflow pipe q , and finally also the valve P ¹ with the front part of the cylinder b and with another outflow pipe q ¹ . These six valves are arranged in two groups of three, namely MNP and M ¹ N ¹ P ¹ ; the valve rods m η ρ are connected by a plate r, the valve rods m ¹ n ¹ p ^{l of} the other group by the plate r ¹ in a similar manner.

A thumb disk f ¹ with three thumbs i, 2, 3 is arranged on the motor shaft f; the thumb disk f ^l is such loose out, that they can move laterally and is held between two rings / ^2/3 system. During normal walking, one end of a lever s lies against the thumb 2, while the other end is connected to the plate r by a pivot rod s ¹ (FIG. 1).

Furthermore, one end of a lever t lies against the thumb 1, while the other end is connected to the plate r ¹ by means of the toggle rod t ^1.

Since the valves are the same, it suffices to describe one of them. The valve M (Fig. 3) is equipped with a valve seat in ' ² on which the actual valve body M rests. The latter is the action of a spring m ^s subject, which tends to push the valve resistant against its seat and to lift the plate r. The spindle m is guided in a faceplate. The valve has a connection w ⁶ through which the gas entering at m ⁷ escapes after passing through the valve M. The valve M is also equipped with a flange m ^s , which

is fastened by means of a screw or the like on a plate u (Fig: ι), which in turn carries all six valves and is arranged on the frame c in such a way that the valves can be easily examined, since after removing the plate u the whole motor can be dismantled is. The ring / ³ is provided with an annular groove, into which a neck ring / ^{4 is} inserted, easily movable, which is connected to a fork lever ν , by means of which the ring f ^s and the thumb disk f ^{l are} laterally displaced during the rotation of the axis f can be; Axis f and disk f ¹ are connected by means of a keyway and spring. Accordingly, when the thumb 2 of the thumb disk f ^l lets the lever s swing around, the toggle rod s ^l lowers (FIG. 1), the plate r going down together with the three valve bodies MNP. The gas entering through the pipe g passes through the free annular space between the valve body M and the seat wj ² and passes through the channel m ⁶ to the rear part of the cylinder a. ■ The piston a ^{1 of} the latter is advanced while the gas on the other side escapes from the cylinder and enters the valve N , the valve body of which is raised. The gas thus enters the cylinder b , the piston b ¹ being driven backwards and the gas itself expanding. The gas which is located behind the piston b ^l flows through the pipe ρ ^β into the valve P and escapes through the pipe q to the atmosphere. When the piston a ^{1 has reached} the end of its forward travel and the piston b ¹ backward at the end of its travel, the thumb 2 of the thumb disk f ^l no longer acts on the lever s and the springs m ^s (Fig. 3) press the lever s again against the cylindrical part of the thumb-disk, while under the influence of the same springs the plate r and the rear valve bodies are raised, and the latter lie back on their seats. If the thumb 1 of the thumb disk f ¹ then acts on the lever t, the plate r ¹ with the three front valves M ¹ N ¹ P ^{1 is} lowered. The gas flows through the pipe g to the valve Af ¹ and from here into the front part of the cylinder α, whereby the piston a ^{1 is} driven backwards. The gas which is behind this reaches the valve iV ¹ and from there to the rear part of the cylinder £, where it expands in the cylinder and propels the piston b ^] . The gas that is in front of this piston enters the valve P ¹ and escapes through the pipe ^ ¹ . At the end of the barrel the thumb 1 leaves the lever i, which the latter lowers under the influence of the articulated lever i ¹ (Fig. 1) by the influence of the springs and the plate r ¹ and the front valves lifts. The thumb 2 acts again on the lever s to lower the rear valves and the game repeats itself as described above. If you want to change the direction of rotation of the motor, you set the lever ν in such a way that the thumb 2 moves more towards the center of the frame c , so that then the thumb 3 is in the area of the lever s and the thumb 2 in the area of the lever f arrives while the thumb 1 is completely turned off. The engine can also work with a similar compressed gas and the number of Cylinder can be enlarged as required. Patenτ claim: Control for engines with operation by carbon dioxide or similar gases, thereby marked that the six valves of the machine in two groups of three valves each are summarized, each of which by a lever of a thumb disk with three Cam is actuated, the cams being arranged such that by displacement the thumb disc on its shaft can cause a reversal of the machine. 1 sheet of drawings.
