Rotiren de machine.

The first part of the innovation relates to the construction of circular arcs Outflow valves and the connection of the same to a comb disc through which the correct movement of these valves is established at high speed and low pressure.

The second part of the innovation relates to the connection of the piston with one Disk, between the arms of which the piston protrudes in the tangential direction is, as well as a new kind of piston lifting.

The third part of the innovation relates to the means by which the movement of the Machine is reversed.

Figure 2- is the end view of the machine;

Fig. 3 shows the piston enlargement on an enlarged scale;

Figure 4 is a vertical section through the center of the machine showing the annular steam chamber; -

Fig. 5 shows the valve for reversing movement in section;

Fig. 6 shows the valve box of a single-acting machine;

7 shows a vertical section through the machine, perpendicular to the operating shaft;

FIG. 8 shows a horizontal section through FIG. 6.

The housing in which the piston rotates consists of two cast halves A ¹ A ² , each of which has an annular space α on its end face.

If both halves are screwed together, these spaces α together form the vapor space in the form of a hollow ring, in which the piston D of rectangular cross-section fits. This piston is connected to the hollow drive shaft E by the disk C. The disc C is sealed in the housing by the packings FF lying in the circular depressions a ¹ a ^l , which are best made of rubber and prevent the escape of the steam from the hollow ring on the disc C.

The piston D consists of a metal block, the outer wall of which is convex, the inner but concave of which is adapted to the inner walls of the housing. It is sealed by means of two metal rails bent at an angle , which are embedded in the grooves of the piston and, as FIG. 3 shows, are pressed against the walls of the steam chamber by spiral springs.

The piston is provided with a hole to accommodate a pin of the disk C. Two tangential arms d of the disc embrace the end faces of the piston and form part of the piston body. In these arms, two radially standing steam channels e ″ 'are attached, which run out from the sleeve K in the interior of the drive shaft on both sides of the piston, as FIG. 1 shows.

Claims (2)

At the two opposite ends of the housing A ¹ A ^2, the valve boxes G project , which are in communication with the steam space inside the housing and are provided with outflow openings IT. In each valve box, reciprocating, circular arc-shaped valves L are mounted, the lips / of which adjoin the inner wall of the valve box tightly. In the position of the piston in FIG. 1, the lower lip / the valve on the right-hand side closes the hollow ring serving as a steam chamber, while the upper lip / the valve on the left-hand side has an analogous position. The lying on the other side of the valve pivot lip, however, opens the connection of the pits M on the sides of the valve box with the flow-out hole H by means of the cock MK These taps M ¹ in two valve boxes are connected by suitable means with each other to the movement in the reversal to change the connection of the outflow H with the cavities. Under normal circumstances the movement of the valves L is already regulated by the force of the escaping steam; But so that the regular operation of the valve takes place with rapid movement of the machine under low pressure, the axis of rotation of each valve L is extended and carries the lever N, at the free end of which a guide roller is attached, which is in the eccentric groove η one on the drive shaft seated comb disk P engages. Half of the groove η is concentric, but the other half is composed of three short arcs, whereby the play of the valve L is ensured under all circumstances without any significant expenditure of force. The device for reversing the movement is shown in FIG. 5 and consists of the reversing valve K and the ring k. The inserted into the hollow drive shaft E ¹ sleeve K is through an opening at one end, depending on whether it is rotated, with one or the other steam channel e and e ¹ on one or aqderen side of the piston in connection. The rotation of this sleeve K occurs through the displacement of a wedge on the ο shaft slidable ring E k by means of the pin o ^1, which is fixedly connected to the sleeve and passes through a slot of the shaft e. ¹ Inside the ring, a spiral-shaped, winding groove is worked out, in which the free end of the pin o ^{1 is} guided. If the ring k is displaced, the pin o ^x rotates and with it the sleeve K, through which the steam now instead of e to one side of the piston, through e ^x to the other side of the piston and the same to the opposite side Page turns. The taps M " ^{1 are} connected to the ring k by suitable devices, so that the machine can be switched over with a single movement. In FIG. 1, the piston D has the position in which it has passed the valve L on the left by rotating in the direction of the arrow. The lever N on the left , as well as the valve L , which is dependent on it, remain in their position for half a turn because of the concentric part of the groove η, in that the lip next to the piston blocks the steam flowing through the channel e , while the opposite lip prevents the Connection with the outflow. After the piston has passed the valve L on the right and made half a turn, the movement of the valve being effected by the eccentric furrows η , the steam inflow and outflow on the other half of the piston path occurs in the same way, the steam always in one direction and the same side of the piston pushes and the outflow is effected on the right-hand side through the upper half and on the left-hand side through the lower half of the valve in question. The position of the cock M ¹ on the right side of the machine is opposite to that on the left side of the machine, so that the upper part of the valve chamber on the right and the lower part of the valve chamber on the left are connected to the outflow H. If the machine is to be single-acting, flaps must be inside the valve box be cast, which serve to support the protruding end of the valve when the same is closed, and also to the passage of the steam at this valve end to prevent. Such a valve box is shown in FIG. Patenτ claim:
A rotating machine, characterized by: ι. the circular arc-shaped discharge valves Z with protruding lips / in connection with the valve boxes G and the side cavities M, as well as the taps M \ , the position of which causes the steam to escape from the upper or lower part of the valve box, depending on the direction of rotation of the machine; 2. the outflow valves L in connection with the levers N and the comb disc P with the furrows n, through which the closure of the outflow opening is effected with every half revolution of the piston; the device for reversing, consisting of the radially standing steam channels ee ^x opening out on both sides of the piston D in connection with the valve K in the hollow drive shaft £ \ whose pin ο 'moves in a slot of this shaft and mediates one inside the displaceable ring k causes the rotation of the valve and thereby the inflow of steam through one or the other of the channels ee ^l on one or the opposite side of the piston, For this purpose ι sheet of drawings.
