Description

Description
Title of Invention: VALVES FOR STEAM ENGINE WITH
ROTATING PISTON AND DRIVE THEREOF
Technical Field
[0001] The present invention relates to valves for steam engine with rotating piston
designated for conversion of steam energy to mechanical energy and drive thereof.
Background Art
[0002] Present known valves for steam engine with rotating piston and drive thereof are in particular valves controlled through control box, by means of electromagnetic power. However, these designs are considerably general.
[0003] The DE19940088A1 document deals with valves only in very general manner - as electromagnetic one. The shortcoming of this design is that it is too general, expensive and with low lifetime, while it does not deal with specific design of the valve body at all.
[0004] The DE4119242A1 document broadly describes pairs of valves mechanisms (inlet and outlet), controlled by control unit. This means that they are controlled by electromagnetic power and driven by electromagnetic energy or compressed air. This design is relatively expensive with short lifetime. At the same time, this document does not deal with specific design of the valve body.
[0005] The US5410998 document deals with feeding and injecting working medium not through electromagnetic valve, but through sliding mechanism. This sliding mechanism - valve - is very similar to classic valve in a petrol engine. Disadvantage of this design is that it is relatively complicated, hardly realizable. At the same time, according to high temperatures and problematic lubricating, the lifetime of sliding mechanism is relatively limited.
[0006] The WO2009/005480A1 document designs valves as rotary bodies, drive thereof by means of electromagnetic power, or mechanically - by means of a belt, or a chain, or cogwheels. However, this application does not deal with specific design of valve body and specific manners of connecting valves with the engine shaft.
Disclosure of Invention
[0007] Mentioned shortcoming are eliminated to the substantial degree by valves for steam engine with rotating piston and drive thereof, according to the present invention, the substance whereof resides in that the cylindrical rotary body with the cavity is fitted in their casing, concentrically mounted on the back shaft, which is fitted in at least one back bearing fitted in the casing, while the rotary body incorporates at least one body opening along circumference thereof and the casing incorporates at least one pipe opening and at least one engine opening for ensuring pass-over of propelling medium between the pipe and the engine and there is the valve wheel connected to the drive gear mounted on the back shaft.
[0008] The cavity of the rotary body is advantageously opened from the front side and the front flange of the casing is inserted by its inner part and fits into the inside of the cavity and at least one pipe opening is located on the inner circumference part of the front flange and the pipe is connected to the outside part of the front flange and at least one engine opening is located on the casing box.
[0009] The cavity of the rotary body is advantageously closed from the front side and the rotary body is concentrically mounted from the front side on the front shaft, which is fitted in at least one front bearing fitted in closed front flange of the casing and the pipe opening and at least one engine opening are located on the casing box, while a pipe is attached to the pipe opening.
[0010] The back bearing is advantageously secured by the bearing encapsulation by means of the sealing flange mounted on the back shaft and the filling mounted on the back flange and the back bearing fitting tightly to the sealing flange, while there is the valve wheel mounted on the sealing flange from the other side, secured by securing element and nut, which are mounted on the back shaft and the bearing encapsulation is covered by its sealing cover mounted on the back flange and fitting tightly to the valve wheel.
[0011] Drive gear consists of at least one circulating drive element connected to the drive wheel, the valve wheels, at least one tensioner and at least one vibration damper.
[0012] Circulating drive element is advantageously a chain or a belt.
[0013] The drive gear advantageously consists of four valve wheels placed in vertexes of an orthogon and the drive wheel located in the middle among them, while the circulating drive element runs from the drive wheel through at least one tensioner to the first valve wheel, then along circumference of an orthogon to another three valve wheels and then back to the drive wheel, while it runs through at least one vibration damper.
[0014] The drive gear advantageously consists of four valve wheels placed in vertexes of an orthogon and the drive wheel located in the middle among them, while the first circulating drive element runs from the drive wheel through first tensioner to the first valve wheel, then to the second valve wheel and back to the drive wheel, and the second circulating drive element runs from the drive wheel through the second tensioner to the third valve wheel, then to the fourth valve wheel and back to the drive wheel, while both circulating drive elements run also through at least one vibration damper.
[0015] At least one circulating drive element is advantageously connected to at least one auxiliary wheel. [0016] The drive gear advantageously consists of two valve wheels and the drive wheel located in the middle among them, while the circulating drive element runs from the drive wheel through tensioner to the first valve wheel, then through auxiliary wheel to the second valve wheel and back to the drive wheel, while it runs also through at least one vibration damper.
[0017] Advantages of described design are in particular that such design of valves and drive thereof by the drive gear is simple, easy to realize, cheap, reliable and with long lifetime. Another advantage is the possibility of regulation of filling by means of securing element.

Mode(s) for Carrying Out the Invention
Mode l
[0033] The Figure 1 shows the valve 1 with one engine opening 25, where the pipe 6 is connected concentrically with the rotation axis. The casing 2 consists of the box 21, which is closed by the front flange 22 from the front side and by the back flange 23 from the back side. The cylindrical rotary body 3 with the cavity .31, which is concentrically mounted on the back shaft 4, is fitted in revolving manner in the casing 2. That is fitted in the back bearing 41 mounted on the back flange 23. The cavity 31 of the rotary body 3 is opened from the front side and the front flange 22 is inserted by its inner part and fits into the inside of the cavity 3L The pipe 6 is connected to the outside part of the front flange 22. The pipe opening 24 is located on the inner circumference part of the front flange 22, the body opening 32 is located on the circumference of the rotary body 3 and the engine opening 25 is located on the box 21, while all three openings are located on the same rotation path. These openings serve for ensuring pass-over of propulsion medium between the pipe 6 and the engine. The back bearing 41 is secured by the bearing encapsulation 7 by means of the sealing flange 71 mounted on the back shaft 4 and the filling 72 mounted on the back flange 23. Valve wheel & secured by the securing element Sl, consisting of frictional casing and nut 82, which are mounted on the back shaft 4, are mounted on the sealing flange 21 from the other side. The bearing encapsulation 7 is covered by its sealing cover 73 mounted on the back flange 23 and fitting tightly to the valve wheel &. Four described valves 1 are connected to the drive gear 9 by means of their valve wheels & (Figure 6). Two valves 1 are connected as inlet valves 1 to inlets of the engine and two valves as outlet valves 1 to outlets of the engine. Four valve wheels & are placed in the drive gear 9 in vertexes of an orthogon and the drive wheel 91 is placed in the middle among them. The circulating drive element 93, which consists of chain, runs from the drive wheel 91 through the tensioner 95 to the first valve wheel &. Then it runs along circumference of an orthogon to other three valve wheels £, while it runs between every two valve wheels £ through one vibration damper 94. It continues from the fourth valve wheel & through last vibration damper 94 back to the drive wheel 9L
[0034] The drive wheel 91 transfers torque through the circulating drive element 93 to the valve wheels & of all four valves. The torque is transferred on each valve 1 from the valve wheel £ through the sealing flange 21, the securing element £1 and the back shaft 4 to the rotary body 3. By turning the rotary body 3, regular timed overlapping of the pipe opening 24, the body opening 32 and the engine opening 25 occurs. Thereby regular timed release and closing of propulsion medium between the engine and the pipe 6 occur. In case of inlet valves 1 connected to inlets of the engine, there is release in the direction from the pipe 6 into the engine and in case of outlet valves 1 connected to outlets of the engine, there is release in the direction from the engine to the pipe 6.
Mode 2
[0035] The Figure 3 shows the valve 1 with two engine openings 25, where the pipe 6 is connected concentrically with the rotation axis. This valve 1 is designated for the engine with two rotating pistons. The design of this valve 1 contains all elements as described in the example 1 with such difference, that it contains also one trio of openings, namely the second pipe opening 24 on the inner circumference part of the front flange 22, the second body opening 32 on the circumference of the rotary body 3 and the second engine opening 25 on the box 21, while these openings are located in the same rotation path, which is shifted compared to the rotation path of the first trio of openings. The second pipe opening 24 is located in the same angle of turn as the first pipe opening 24. The second engine opening 25 is also located in the same angle of turn as the first engine opening 25. The second body opening 32 is turned by 180° angle compared to the first body opening 32.
[0036] Transfer of the torque between the drive wheel 91 and the rotary bodies 3 in the example 2 is the same as in the example 1 (Figure 6). By turning the rotary body 3, regular timed overlapping of first pipe opening 24, first body opening 32 and first engine opening 25 on first rotation path and second pipe opening 24, second body opening 32 and second engine opening 25 on second rotation path, occur. Thereby regular timed release and closing of propulsion medium between the engine and the pipe 6 occur. Each rotation path appertains to other piston of the engine. Therefore mutual timing of paths is shifted.
Mode 3
[0037] The Figure 2 shows the valve 1 with one engine opening 25, where the pipe 6 is connected perpendicularly to the rotation axis. The casing 2 consists of the box 21, which is closed by the front flange 22 from the front side and by the back flange 23 from the back side. The cylindrical rotary body 3 with the cavity 3_1, which is concentrically mounted on the back shaft 4, is fitted in revolving manner in the casing 2. That is fitted in the back bearing 41 mounted on the back flange 23. The cavity 31 of the rotary body 3 is closed from the front side and the rotary body 3 is fitted from the front side concentrically on the front shaft 5, which is mounted on the front bearing 5_1 fitted in closed front flange 22. There is the pipe opening 24 and the engine opening 25 , which are mutually turned by 180°, on the box 2L There are two body openings 32, which are also mutually turned by 180°, on the circumference of the rotary body 3. The pipe opening 24 and the first body opening 32 are located on first rotation path and the engine opening 25 and the second body opening 32 are located on the second rotation path, which is shifted compared to the first rotation path. The pipe 6 is connected to the pipe opening 24. These openings serve for ensuring pass-over of propulsion medium between the pipe 6 and the engine. The back bearing 41 is secured by the bearing encapsulation 7 by means of the sealing flange 71 mounted on the back shaft 4 and the filling 72 mounted on the back flange 23. The valve wheel & secured by the securing element SX, consisting of toothing and nut 82, which are mounted on back shaft 4, are mounted on the sealing flange 71 from the other side. The bearing encapsulation 7 is covered by its sealing cover 13, mounted on the back flange 23 and fitting tightly to the valve wheel S. Four described valves 1 are connected to the drive gear 9 by means of their valve wheels S (Figure 7). Two valves 1 are connected as inlet valves 1 to inlets of the engine and two valves as outlet valves 1 to outlets of the engine. Four valve wheels S are placed in the drive gear 9 in vertexes of an orthogon and the drive wheel 91 is placed in the middle among them. First circulating drive element 93, consisting of a belt, runs from the drive wheel 91 through the first tensioner 95 to the first valve wheel S, then to the second valve wheel S through the first vibration damper 94 and through the second vibration damper 94 back to the drive wheel 91, and the second circulating drive element 93, consisting also of a belt, runs from the drive wheel 91 through the second tensioner 95 to the third valve wheel S, then through the third vibration damper 94 to the fourth valve wheel S and through the fourth vibration damper 94 back to the drive wheel 9L
[0038] The drive wheel 91 transfers torque through two circulating drive elements 93 to the valve wheels S of all four valves. The torque is transferred on each valve 1 from the valve wheel S through the sealing flange 71, the securing element £1 and the back shaft 4 to the rotary body 3. By turning the rotary body 3, regular timed overlapping of the pipe opening 24 and the first body opening 32 on the first rotation path and the second engine opening 25 and the second body opening 32 on second rotation path occur simultaneously. Thereby regular timed release and closing of propulsion medium between the engine and the pipe 6 occur. In case of inlet valves 1 connected to inlets of the engine, there is release in the direction from the pipe 6 into the engine and in case of outlet valves 1 connected to outlets of the engine, there is release in the direction from the engine to the pipe 6.
Mode 4
[0039] The Figure 4 shows the valve 1 with two engine openings 25, where the pipe 6 is connected perpendicularly to the rotation axis. This valve 1 is designated for the engine with two rotating pistons. The design of this valve 1 contains all elements as described in the example 3 with such difference that it contains one more pair of openings located in third rotation path shifted compared to first two rotation paths. These openings are the second engine opening 25 located on the box 21 in the same angle of turn as the first engine opening 25 and the third body opening 32 located on the circumference of the rotary body 3 turned by the angle of 180° compared to the second body opening 32. Furthermore, there is fourth body opening 32 turned by 180° compared to the first body opening 32 in the first rotation path.
[0040] Transfer of the torque between the drive wheel 91 and the rotary bodies 3 in the example 4 is the same as in the example 3 (Figure 7). By turning the rotary body 3, regular timed overlapping of the pipe opening 24 and first and fourth body openings 32 on first rotation path, first engine opening 25 and second body opening 32 on second rotation path and second engine opening 25 and third body opening 32 on third rotation path occur. Thereby regular timed release and closing of propulsion medium between the engine and the pipe 6 occur. Second and third rotation paths appertain to other piston of the engine. Therefore mutual timing of paths is shifted.
Mode 5
[0041] The Figure 8 shows the drive gear 9, where two valves 1 are connected as inlet
valves 1 by means of their valve wheels &. The drive wheel 91 is located between these two valve wheels 8. The circulating drive element 93, consisting of a belt, runs from the drive wheel 91 through the tensioner 95 and the first vibration damper 94 to the first valve wheel S, then through the auxiliary wheel 92 and the second vibration damper 94 to the second valve wheel £ and through third vibration damper 94 back to the drive wheel 9L
[0042] The drive wheel 91 transfers torque through circulating drive element 93 to the valve wheels & of both valves 1.

[0044] Given examples does not include all possible embodiments of the design.
