Explosion engine.

The subject matter of the invention relates to an explosion engine with a working piston and a smaller control piston.

Fig. Ι shows such a machine in section.

Figure 2 illustrates the crank diagram of this machine.

Fig. 3 shows another embodiment of this machine.

Figure 4 illustrates the crank diagram of the second machine.

The machine (Fig. 1) consists of the cylinders A and £>, which are connected by the squire C and fixed on the crankcase D.

In cylinder A , piston E works on crank F, which exposes slots H of cylinder A in the lower dead center.

In cylinder B , the piston E _{1 works} on the crank F ₁ , which opens the ring channel I with the exhaust port L in the lower dead center position.

The slots H of the cylinder A are by means of a channel. K is connected to the inflow port M when the annular groove N of the piston E _{1 is} at the same height as the inflow port M.

On the waves of the cranks F and F _1, the gears G and G sitting _1, of which the gear G ₁ twice as large than the gear G.

In the machine of FIG. 3, the crankcase consists of two parts D ₁ and D ₂ which are connected by pipe S.

The transmission of the movement from gear G to gear G ₁ is effected by gear C ₂ .

The cylinder A is provided with slots R which open into the tube Q. The inlet valve P is attached to the squire C.

The operation of the machine illustrated in FIG. 1 is as follows.

While (see Fig. Chart of Fig. 2) of the crank F i _a to 2 _a is E and the piston from the lower position upwardly moves, passes the offset by 45 ° crank F ₁ of

3 * ^after Ab- The canal / is made so wide that

it is open during the crank travel 5 ^ to 4 ^ and thus can exhaust the burnt gases during the high gear of the piston E.

At the end of the exhaust the piston E moves downwards and the crank F moves from i _a to \ _a and opens the slots H _{from 4 a} to 5 ^. As a result of the pressure reduction which has formed on the way 2 _a to 4 ^, fresh mixture penetrates through pipe MK into cylinder A, since crank F ₁ goes from 6 _b to j _b during this time, and the groove N of piston E ₁ connects pipes M and. K connects. After the suction has ended, compression and expansion take place.

The operation of the machine illustrated in FIG. 3 is as follows.

When the crank F moves from 1 _a to 2 _a (see Fig. 4), the crank F ₁ rotates from I ₆ to 2 _h . During this period

Claims (6)

the burned gases are exposed through the slits I and the connecting piece L. Then the crank F rotates from 2 _a to 3 _a and crank F ₁ from 2 _b to 3 ^, with suction
finds. of the mixture through valve P instead - at the same time, piston E compresses mixture in capsules D ₁ and D ₀ . In the crank positions 3 ^ to \ _b , piston E ₁ exposes the openings O which connect the interior of the capsules D ₁ and D ₂ with the tube K in the highest position. Since the crank F is now in the position in which its piston E exposes the openings H , there is an overflow of compressed mixture from the capsules into the cylinder A on the path 3 ^ -4 ^, which is sucked in through valve P. Mixture increased. Now the compression begins, which is followed by explosion and expansion. The new mixture is sucked into the capsules through the channel R and the inflow pipe Q, which takes place when the piston E moves upwards. The capsules D ₁ and D ₂ are connected to a carburator which is connected to Q. This suction takes place only with every second stroke, because only every second time there is an overflow of the compressed mixture through the pipe K and accordingly a negative pressure is created only every second time. If one denotes the volume of the large cylinder with Z ₁ , the volume of the control _{cylinder with z 3} and the volume of the capsule C with z ₂ , the following spatial relationships result approximately for the different work phases: The channels of the small cylinder open at a crank position of 45 ° from the lower dead center. This gives about ¹ I _{1 of} the cylinder space. 6th The total space after the expansion is finished is Z ₁ -J- Z ₂ - | Z ₃ , of the outer fabric is z ₂ -1 z ₃ , Suction is I ₁ -J- z ₂ - | --—,
of compression z ₂ - | —— · This is only true for the expansion, while for the other phases through the Movement of the small piston causes negligible errors. The expansion space is - Z _{3 larger} than the suction space. Since the control cylinder itself contains only Y ₁₀ to Y _{16 of} the largest cylinder, this deviation is practically insignificant. Patent language: ι. Explosive engine with a working piston and a control piston of unequal cross-section, characterized in that the smaller piston (E ₁ ) only reciprocates during a four-stroke cycle of the larger piston (E) and controls the inlet and exhaust ports (L and M) . 2. An explosion engine according to claim i, characterized in that in addition to the mixture sucked in through the suction valve (P) at the end of the suction stroke, a further amount of mixture from the crank chambers (D ₁ and D ₂ ) is pushed over into the working cylinder (A). 1 sheet of drawings.
