ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention generally relates to propulsion blades for a device, such as a disk pump. More specifically, the present invention relates to a propulsion blade having at least one irregularity or contour in a surface of the blade that is identically repeated in a series of blades for use in device, such as a pump, an engine or the like.
It is, of course, generally known to provide pumps or engines that are designed to use and implement a plurality of blades stacked one atop another with minimal spacing therebetween. The blades, upon high speed rotation, provide an engine or motor with the highest possible power output using a minimum amount of energy. The power is derived from the force imparted through rotation of the blades by, for example, impact, adhesion, viscosity and static expansion derived from a fluid such as gas, steam, water, air, or the like when forced upon the rotating blades.
Known blades used for this purpose are typically planar and are stacked as a series of parallel blades. It is known, for example, in U.S. Pat. No. 1,047,898 to provide an engine with rotor blades or plates having circumferential teeth adapted to receive the direct impact of a fluid as well as the faces of the disk receiving the impact of the fluid thereby resulting in a higher starting torque and increased power at all speeds. In operation, fluid is introduced through an inlet port and directed against serrations about a circumference of the disk thereby imparting a propulsive force thereto. The impact of the fluid against the face of the disk takes a spiral course. The length of the spiral course corresponds to the speed of rotation of the plates. As a result of the direct impact upon the disk together with the adhesion of the fluid to the disk, a high starting torque results in a corresponding increase.
A need, however, exists for an improved disk and/or parallel spaced disks used, for example, in a pump to further improve the efficiency and output power of the device in which the blades are implemented.
SUMMARY OF THE INVENTION
The present invention generally relates to a disk or a plurality of disks as well as a pump, motor, or other device that uses those disks to increase efficiency and power output of the device.
To this end, in an embodiment of the present invention, a blade is provided. The blade is a circular disk that has a central opening wherein the disk is constructed from a stamped material forming a single planar layer with an equal radius defining an outer periphery of the disk. A first rib is integrally formed in the material creating a non-planar section of the disk wherein the first rib is formed circumferentially and equidistantly around the disk at a point intermediate the central opening and the outer periphery of the disk.
In an embodiment, at least one additional rib is integrally formed in the material creating a non-planar section of the disk wherein the at least one additional rib is formed circumferentially and equidistantly around the disk at a point intermediate the central opening and the outer periphery of the disk and at a point distinct from the first rib.
In an embodiment, the first rib and the at least one additional rib are substantially identically shaped.
In an embodiment, the material is a metal.
In an embodiment, the central opening is circular.
In another embodiment of the present invention, a rotor is provide. The rotor has a plurality of blades wherein each of the plurality of blades has a central opening. Each of the plurality of blades is positioned in a parallel relationship with their central openings aligned. Each of the plurality of blades has an equal radius defining an outer periphery of each of the plurality of blades. An integrally formed rib is provided in at least one of the plurality of blades creating a non-planar section of the at least one of the plurality of blades wherein the rib is formed circumferentially and equidistantly around the disk at a point intermediate the central opening and the outer periphery of the disk.
In an embodiment, an integrally formed rib is provided in each of the plurality of blades.
In an embodiment, each of the integrally formed ribs are stamped equidistantly and circumferentially from the central opening of each of the plurality of blades.
In an embodiment, at least one additional rib is integrally formed in the at least one of the plurality of blades. At least one additional rib is integrally formed in each one of the plurality of blades.
In an embodiment, each of the at least one additional ribs are stamped equidistantly and circumferentially from the central opening of each of the plurality of blades.
In an embodiment, the central opening of each of the plurality of blades is circular.
In an embodiment, each of the plurality of blades is metallic.
In an embodiment, each of the ribs are substantially identically shaped.
In another embodiment of the present invention, a device is provided. The device has a housing that has exterior walls defining an interior wherein the interior is capable of receiving a fluid therein. A plurality of blades is provided within the interior of the housing, each of the plurality of blades having a central opening wherein the plurality of blades have an equal radius defining an outer periphery.
A shaft is provided on which each of the plurality of blades is rotatably attached. A first rib is formed in each one of the plurality of blades wherein the rib is equidistantly and circumferentially stamped in each of the plurality of blades.
In an embodiment, an additional rib is provided in each one of the plurality of blades wherein the additional rib is equidistantly and circumferentially stamped in each of the plurality of blades at a position intermediate the central opening and the outer periphery and distinct from a position of the first rib.
In an embodiment, the plurality of blades are metallic.
In an embodiment, the first rib and the additional rib are substantially identically shaped.
In an embodiment, the central opening is circular.
It is, therefore, an advantage of the present invention to provide a disk as well as a device implementing a plurality of the disks which incorporates disks which may be manufactured by stamping the disks.
Another advantage of the present invention is to provide a disk and a device incorporating a plurality of those disks that allows for thinner layers of metal to be implemented to achieve the same efficiency.
Yet another advantage of the present invention is to provide a disk and device implementing a plurality of those disks that provides greater efficiencies and pumping capabilities.
Additional features and advantages of the present invention are described in, and will be apparent from, the detailed description of the presently preferred embodiments and from the drawings.
