IMPERIAL

PATENT OFFICE.

The invention relates to a controller for Explosion engines by a controlled pipe slide and one of this temporarily taken auxiliary slide (drag slide). The invention consists in that the cylinder head is designed as a drag valve by being carried along by the controlled slide sleeve in one direction and in the other direction by springs again

ίο is moved back.

This arrangement makes it possible for the purpose of cleaning or the like. In a few minutes the as Dismantle cylinder head trained slide. It's just the head screws which connect the cylinder cover to the cylinder, unscrew, then you have the Cylinder head working as a slide under the cylinder cover.

The arrangement made makes it possible furthermore, that the burnt gases are quickly and almost completely removed, because when they are expelled the same piston and head run towards each other and stand close together when the exhaust pipe closes.

In the drawing, an embodiment of the subject invention is shown, and although shows

Fig. Ι a four-stroke engine with the device in section and the state of the Passages in the middle of the compression period;

Fig. 2 shows the position of the slots and channels at the lowest position of the slide sleeve and of the head (middle of the exhaust period);

Fig. 3 shows a diagram of the course of the Sehieberhülse.

The cylinder α has a removable cover &; On the latter are the two lugs c and c ¹ , which are pierced so that the two pins d and d ¹ can move up and down in the hole. These pins are firmly connected to the head f . In the space between c, c ¹ and f there are springs g, g ¹ ' around pins d and d ¹ , which are tensioned when the head goes up. The gasketed rings head f filled including the rings in the bore of the cylinder a only so far that the sliding sleeve between f h., And α, and may go down. The cylinder α has a slot or a channel on the left and right, as well as the slide sleeve h and the head f. The slots or channels on the left side are for fresh gas entry, those on the right side for the exit of the burnt gases. The height of the slots in the slide sleeve is dimensioned so that gas admission takes place for the full intake period and gas outlet for the full exhaust period.

The mode of action is as follows:

The slide sleeve h is controlled, for example, with a 30 mm stroke by the control crankshaft, which in turn is driven by the main shaft with a ratio of 1: 2, as is necessary with four-stroke engines. (The division of the periods, based on the rotation of the control shaft, results from the diagram in Fig. 3.)

The head f can cover a distance of 20 mm up or down, and indeed it is temporarily moved along by the slider sleeve h.

Claims (1)

taken and moved back by the springs g, g ¹ . The safety of the head staying up until the beginning of the explosion is ensured by the compression, the explosion keeps it higher up. Fig. Ι now shows the highest level of the slide sleeve h and the head f, which corresponds to the middle of the compression period. After 4 ¹ Z ₂ mm decline of the sleeve h is the ίο Compression period ended, the explosion period begins, and this ends after 4 ¹ Z ₂ + 20 mm decline. At this moment the lowest part of the slot of h reaches the uppermost part of the exhaust port of cylinder a, the exhaust thus begins. After 4% + ²⁰ + 5 ¹ U ^mm = total decline of the sleeve h , it reaches its lowest level, the middle of the exhaust period. Since head f is freed from the explosion pressure holding it up when the exhaust begins, it is meanwhile driven downwards by the spring pressure. It is of particular importance that the device allows a relatively considerable height of the outlet slot from h and the outlet slot or channel from f , because this allows the burnt gas to escape unhindered through the slower or faster decline of f , with the exhaust still closed in good time will. The lowest position of the sleeve h is therefore in the middle of the exhaust period. If it now goes up 5 ¹ Z ₂ mm again, the exhaust is closed. closed because the uppermost part of the outlet of f is then overrun by the slit of the slide sleeve. The gas inlet slot of the slide sleeve has not yet reached the inlets of the cylinder and head, this only begins after a further 4 ¹ / _2- mm path in order to produce a dilution of the cylinder contents in order to accelerate the fresh gas admission that then follows. After the slide ^{sleeve has risen from 5 1} Z ₂ - | - 4 ¹ Z ₂ mm as described above, the uppermost part of the admission slot in the slide sleeve reaches the gas inlet of the cylinder and head f, fresh gas enters. After ^{climbing 15 1} Z ₂ mm further, the slit of the slide sleeve has passed the inlet of the cylinder, taking the head f with it, the gas inlet is closed. Now compression begins and the middle of the compression period is reached again when the slide sleeve rises ^{by 4 1} Z _{2 mm (= end of the slide sleeve stroke).} The rise of the head is gently caused by the slide sleeve according to the given path and thus the resistance of the springs is overcome. Ρλτεντ claims: Control for explosion engines by a tubular slide and an auxiliary slide temporarily entrained by this, characterized in that the cylinder head (f) is designed as an auxiliary slide. 1 sheet of drawings.
