SPHERICAL ENERGY CONVERTER

Abstract

The invention relates to a spherical working chamber and to two flat rotary pistons as internally turning, rotating pistons that are used to produce energy, which flat rotary pistons are driven by means of a descent of creeks, rivers or gray water and rainwater from high-rise buildings. Because of the even rotation of the output shaft of the flange-mounted transmission, an electrical generator can be connected. The energy converter plus generator can also be used as a mobile unit in emergency situations at waterfalls in order to generate electricity.

DETAILED DESCRIPTION

[0033] In the following descriptions, the present invention will be explained with reference to various exemplary embodiments. Nevertheless, these embodiments are not intended to limit the present invention to any specific example, environment, application, or particular implementation described herein. Therefore, descriptions of these example embodiments are only provided for purpose of illustration rather than to limit the present invention.

[0034] The spherical energy converter shown in FIG. 8 consists of a housing 1 which confines a spherical working chamber.

[0035] Mounted in the housing 1 are 2 hollow shafts 3a and 3b, whose axes coincide with a diameter of the spherical housing 1.

[0036] As can be seen from FIG. 5 the hollow shafts 3a and 3b have been pushed on the shaft 2. The spherical flat rotary pistons 4 and 5 are respectively connected fixedly to the hollow shaft 3a and 3b. Welding, casting from one piece or milling from one part are options.

[0037] The hollow shaft 3a is connected torque proof to the shaft 2 by way of a wedge-shaped groove, bolt or welding, while the hollow shaft 3b is rotatably mounted.

[0038] The two spherical flat rotary pistons have a circular profile such that they bear sealingly against the inner wall of the housing 1. Put more precisely, each spherical flat rotary piston 4, 5 consists of two spherical semicircular vanes. The two spherical vanes are connected torque proof to the hollow shaft 3a and 3b in the first half of the straight region of their base line. The second half of the base line slides sealingly over the opposite hollow shaft 3a or 3b.

[0039] The two spherical flat rotary pistons 4, 5 consequently confine in the housing 1 a total of 4 chambers I, II, III and IV, as shown in FIGS. 1-4.

[0040] As shown in FIG. 10, a groove is cut out in the sealing surfaces of the spherical flat rotary pistons 4, 5, into which groove a seal 18 is inserted.

[0041] As illustrated in FIG. 5 the hollow shaft 3b, by way of the outer right-hand end, is connected via a freewheel clutch 14 to the toothed gear 6, and a toothed gear 7 is connected via a freewheel clutch 15 to the outer end of the shaft 2, which outer end projects from the hollow shaft 3a.

[0042] The two toothed gears 6 and 7 mesh with a toothed gear 8 which is connected torque proof to an output shaft 9 which is parallel to the shafts 2, 3.

Functioning Principle

[0043] FIG. 1 The medium (gas or liquid) enters the chambers I and III through the inlet openings 11 continuously.

[0044] Accordingly, the flat rotary piston 4 is pushed in a forward direction of rotation, while the rear flat rotary piston 5 would then be driven backward. However, since a freewheel bearing 13 in FIG. 5 activates between the hollow shaft 3b and the housing 1 in FIGS. 7, 8 the flat rotary piston 5 is blocked from rotating backward.

[0045] When the front flat rotary piston 4 is pushed forward, the medium in II and IV is subjected to pressure and is pressed out via the outlet openings 10.

[0046] By way of the rotational movement of the flat rotary piston 4 (see FIG. 2) which is connected torque proof to the hollow shaft 3a and the shaft 2, the toothed gear 7 is driven by the blocked clamping body freewheel 15.

[0047] The toothed wheel 7, by way of the meshing, transmits the rotational movement to the output toothed gear 8, and the output shaft 9, which is fastened to the output toothed gear 8, rotates. As soon as the shaft 2 stops after the working stroke, the clamping body freewheel 15 allows the toothed gear 7 to continue to rotate on the shaft. Pushing-onward of the flat rotary piston 5, as can be seen in FIG. 4 can be achieved by the following options:

A) An engagement bolt 16 which is fastened to the flat rotary piston 4 pushes the flat rotary piston 5 into the next position.
B) A flywheel 19 (FIG. 11) is fastened to the each of hollow shaft 3b and the shaft 2, said flywheels pushing the flat rotary pistons beyond the dead center.

[0048] As soon as the flat rotary piston 5 is rotated over the inlets 11, the pressure builds up in the chambers II and IV.

[0049] The flat rotary piston 5 is now pushed in a forward direction of rotation, while the rear flat rotary piston 4, which is connected torque proof to the clamping body freewheel 12 in FIG. 5 is prevented from giving way into the opposite direction.

[0050] The clamping body freewheel 12 is inserted into the housing 1 and secured against rotation. When the flat rotary piston 5 is pushed forward, the medium in I and III is subjected to pressure and is pressed out via the outlet openings 10.

[0051] By way of the rotational movement of the flat rotary piston 5 (see FIG. 4), which is connected torque proof to the hollow shaft 3b, the toothed gear 6 is driven by the blocked clamping body freewheel 14 (in the toothed gear 6, not visible).

[0052] The toothed wheel 6, by way of the meshing, transmits the rotational movement to the output toothed gear 8, and the working shaft 9, which is fastened to the output toothed gear 8, rotates. As soon as the hollow shaft 3 stops after the working stroke, the toothed gear 6 can continue to rotate on the shaft due to the clamping body freewheel 14. This process is repeated continuously.

[0053] As has been explained above, when the spherical energy generator operates, stepwise rotation of the two flat rotary pistons 4, 5 occurs, wherein, in an alternating manner, one of the two flat rotary pistons performs a working stroke. A working torque is therefore exerted clockwise on the hollow shaft 3b and the shaft 2 in an alternating manner. The clamping body freewheels 14, 15 assigned to the two toothed gears act so that the shaft 2 or the hollow shaft 3b can transmit a drive torque to the assigned toothed gear 7 or 6 in a direction of rotation. However, a toothed gear 6 or 7 driven by the output toothed gear 8 can overrun the corresponding, non-driven shaft 2 or hollow shaft 3b.

[0054] The braking action between the flat pistons 4, 5 can be determined via the spacing between the outlet 10 and the inlet opening 11 on the housing 1.

[0055] The spherically deformed flat rotary pistons (FIG. 9) can counteract the resonance such that vibrations are unlikely and there is no propagation of the latter.

[0056] The semicircular seal 18 (FIG. 10) which bears against the inner surface of the housing 1, is preferably inserted with pretension into the corresponding groove of the flat rotary piston 4, 5, in order that, with increasing wear, said seal can expand radially such that the sealing action is maintained.

[0057] The control times and thus the efficiency can be optimized by way of shut-off slides 20 (FIG. 12) on the flat rotary pistons.

[0058] The efficiency can be increased through the attachment of sensors 22 and electronically controlled solenoid valves 21 to the inlet 11 and 12 (FIG. 13).

[0059] Here are some proposals for the spherical energy converter:

A) In the basement of high-rise buildings, the spherical energy converter may be used for generating electricity by being driven from rainwater or waste water.
B) Use in a tidal power plant, which converts potential and kinetic energy from the tidal range of the sea into electricity, would be conceivable.
C) Use in river power plants would be advantageous since, owing to the high efficiency, only small pressure differences in the water fall height would be required.
D) The energy converter, as a mobile unit, could be used at waterfalls in times of crisis.
E) Use in compressed-air storage power plants would also be conceivable.

[0060] The present invention has been described in detail on the basis of exemplary embodiments for explanatory purposes. However, it is clear to a person skilled in the art that features of the described exemplary embodiments can be combined with features of other exemplary embodiments within the scope of the invention and that it is possible to deviate from the exemplary embodiments within the scope of the invention.
