Abstract

In a preferred embodiment of the present invention, an electric generating device accelerates a plurality of spaced magnetic disks inside a circular chamber. The exterior wall of the circular chamber includes a coil winding, so as the plurality of spaced magnetic discs move within the chamber, an electric current induces in the coil winding. A two-piston mechanical pump drives a gas into traveling compartments located between a pair of the spaced magnetic discs. By forcing fluid into the compartment, the discs are forced to travel within the circular chamber. A set of one-way flow valves ensures that the fluid is uni-directional and directs flow to cause the movement of the discs. A small portion of the generated electricity is returned to the system to energize a pair of helper motors. The electric helper motors, each couple to a respective cam. Rotation of the cams drives the piston pump.

Description

BACKGROUND

The present invention relates to electrical generators and more specifically to an electric generator having pneumatic cylinder piston pump.
An electric generator converts kinetic energy to electrical energy using electromagnetic induction. Typically a motor provides the mechanical energy for conversion. Types of motors used in electric generators include reciprocating or turbine steam engines, moving water channeled through a turbine or water wheel, an internal combustion engine, a wind turbine, or a hand crank.
Each of these types of electromagnetic induction generators apply Faraday's discovery that an electrical conductor moving perpendicular to a magnetic field results in a potential difference, or current, between the opposite ends of the conductor. These principals led to today's generators, a single device that combines an engine and an electrical generator. Generators, which are more precisely termed an engine-generator set or gen-set, in a single device, typically include a diesel or gasoline engine to motivate a rotor relative to a stator. Commonly, the stator comprises either a naturally occurring permanent magnet or an electro-magnet, and the rotor comprises several coil windings that move around the magnetic field of the stator. Small versions of such generators are commonly used to generate electric power on a temporary basis as a standby power generator for a hospital, or as a portable generator for a construction site, for example.
The prior-art electrical generation devices, however, have some limitations. One common limitation of known electric generators includes parasitic losses due to friction between mechanical components. These losses can result in inefficiencies and power loss, typically ranging from 10-40%. Therefore, there is a need for a power generating system that minimizes frictional losses.

DESCRIPTION OF THE INVENTION

Possible preferred embodiments will now be described with reference to the drawings and those skilled in the art will understand that alternative configurations and combinations of components may be substituted without subtracting from the invention. Also, in some figures certain components are omitted to more clearly illustrate the invention.
A preferred embodiment of the present invention uses an inert gas, such as helium in its gaseous state, as a dynamic fluid to motivate a mechanical system coupled to a novel electrical generator. The gas, having fluidic properties, flows, compresses and expands according to well-understood principles and, the terms gas and fluid may be used interchangeably to indicate a gaseous substance. The preferred embodiment of the present invention includes a feedback system that apportions a small portion of the generated electricity to provide mechanical assistance via a motor. The motor can be A/C and draw current directly from the coil assembly, or DC after the alternating current is rectified using a rectifier, which is an electrical device that converts alternating current to direct current or at least to current with only positive value. The motor couples to a cam assembly to power a piston, which drives the fluid pump. Thus, once in a static state, the system according to a preferred embodiment is self-generating with an excess of current available for a storage system or to otherwise exit the system of the present invention.
In a preferred embodiment, an electrical generating device comprises an annular ring assembly coupled to a piston pump and reservoir. As FIGS. 1-6 show, the annular ring assembly 20 consists of a fluid intake means 26, such as a one-way flow valve, or uni-directional check valve to prevent back-flow and direct the gas into the ring assembly. The ring assembly further includes a fluid outflow means 28, such as a one-way flow valve, or uni-directional check valve to prevent back-flow and direct gas out of the ring assembly. Both fluid flow means 26 and 28 are in fluid communication with the piston pump.
The piston pump consists of a first piston assembly 60 having a first variable-volume interior chamber 62. A first inflow check-valve 64 enables fluid or, preferably a gaseous substance such as helium gas, to be drawn into the chamber from the ring assembly when the piston chamber's volume increases and pressure increases. A second outflow check valve 66 enables the gas to displace into a reservoir. The piston assembly includes a first piston adapted to reciprocate within the first variable-volume interior chamber 62 and, includes a compression member 76. A first surface 70 of the first piston forms one wall of the first interior chamber. And, a first connecting rod 74 having a first end couples to a second surface 72 of the first piston in a manner well-understood to those skilled in this art.
A reservoir tank 50, in fluid communication with the first piston outflow check valve 66, uses a fluid flow path, such as piping or intake line 52 to direct fluid or gas from the first piston assembly to the reservoir.
Also in fluid communication with the reservoir, a second piston assembly comprising a second variable-volume interior chamber 82 draws the gas from the reservoir. The second chamber has a second inflow check valve 84 in fluid communication with the reservoir tank. And, a second piston reciprocates within the second variable-volume interior chamber. A first surface 90 of the second piston forms one wall of the second interior chamber. A second connecting rod 94 having a first end couples to a second surface 92 of the second piston. A second outflow check valve 86 in fluid communication with the fluid intake means of the annular ring creates a fluid flow path from the second piston interior chamber to the annular ring assembly.
In a preferred embodiment, the first piston assembly further comprises a link-rod 100 pivotably coupled to the first connecting rod 74 at a second end of the rod. At that same second end, or adjacent thereto, a first cam 110 couples to the connecting rod 74. A small electric, direct current motor draws current from the coil assembly, for example 1.5 amps, and is coupled to the cam directly or by a shaft. Accordingly, whereby rotation of a shaft of the first motor 130 causes the first cam 110 to correspondingly rotate. This rotation is converted into the linear (up/down) displacement of the connecting rod 74 to the first piston assembly.
The link-rod 100 further couples to the second piston assembly at a second end of the second connecting rod 94. Accordingly, upward displacement of the first connecting rod 74 results in a reciprocal but opposite downward displacement of the second connecting rod 94.
The second piston assembly further comprises a second cam 120, which is driven or motivated by a second motor 140, which is similar in design and function as the previously discussed first motor 130, the two motors operating and functioning similarly that the operation and function of the second motor is omitted here.
As FIGS. 2-5 illustrate, as the respective first and second pistons linearly reciprocate, the gas is drawn from the ring assembly into the first piston chamber during the upstroke of the first piston. At the same time, the second piston traveling downward, forces fluid or gas into the ring assembly.
When the first piston reverses and travels downward, the drawn fluid or gas, now prevented from flowing back into the ring by the one way valve 64, forces the fluid or gas into the line 52 via valve 66 and flows to the reservoir tank 50. At the same time, the second piston reverses direction and travels upward. This draws fluid from the reservoir into the chamber using line 54 and one-way valve 84, while valve 86 “closes” and prevents the piston from drawing fluid from the ring assembly.
In a preferred embodiment of the present invention, the electrical generating device also includes an annular ring assembly 20. The annular ring assembly consists of a annular housing 22, which consists of a tubular shaped sidewall with a hollow interior portion, such as channel 24. This forms an interior chamber or, more accurately, a hollow, enclosed pipe channel 24 having a generally circular cross-section. An exterior face of the ring assembly adapts to support a continuous coil-winding 40 about the sidewall's circumference. The hollow interior channel 24 forms a sealed and continuous chamber having a generally circular arrangement wherein no end-walls are required to create the sealed continuous chamber.
Located inside the ring housing, at least one traveling compartment 30 consisting of oppositely position end walls, each end wall being a disc-like or coin-shaped magnetic member. Each traveling compartment 30 locates in the annular housing and adapt to slideably travel within the hollow channel. A first magnetic plate assembly 32 forms one endwall. The first magnetic plate assembly has a generally circular cross section and resembles a coin. The first magnetic plate includes an annular groove 38 adapted to couple to a sealing-ring member 34. The sealing ring member has an outer diameter greater than an outer diameter of the coin-shaped first magnet 32. Oppositely spaced, the second magnetic plate assembly 36 forms a second endwall.
To prevent reverse travel, and to ensure one-directional travel of the traveling compartment 30, a set of one- directional cam devices 25 and 27 are included. Those skilled in the art will appreciate their function, operation, and construction. FIGS. 4, 5, and 6 illustrate the operation of the one- way cams 25 and 27, which ensure one direction travel of the ring 20. FIG. 10B details a possible cam 25 consisting of a pivot element and a small, rotating, triangular-shaped cam member with a travel-limiting and rotational-assist tension device (or spring) that travels from a near horizontal position to enable the magnetic plate to travel in one direction, to its normal, open position, which presents a near vertical sidewall to prevent the reverse travel of the magnetic plate assembly 32 (as shown in FIG. 10A, for example). The vertical position of the cam 25 prevents reverse travel of the plate 32.
A fluid intake means 26, such as a one-way flow valve or check valve, is disposed to create a one-directional fluid flow path to the traveling compartment 30 and a corresponding fluid outflow means 28 comprises an outflow one-way check valve adapted to channel gas or fluid from the traveling compartment and send it to the piston pump.
By Faraday's Law, the voltage generated through the coil by the magnet traveling in the annular housing can be determined. As the disc-like magnet travels past the static coil winding, there is an apparent change in the magnetic field with respect to a given point on the coil winding. And, any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be “induced” in the coil. Faraday's law is a fundamental relationship which comes from Maxwell's equations. It serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment. The induced emf in a coil is equal to the negative of the rate of change of magnetic flux times the number of turns in the coil. It involves the interaction of charge with magnetic field. Thus, the coil winding, in a preferred embodiment, generates about 15 amps.
In a preferred embodiment of the present invention, the generated 15 amps is drawn off the coil winding 40 and split. About 1.5 amps is sent to the pair of AC motors driving the cams via feedback lead 42, and the balance of the generated current is directed to an external device, such as a storage device, battery, appliance, etc. via connector 45.
Although the invention has been particularly shown and described with reference to certain embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
