Description

POWER-TRANSFORMING DEVICE (MOTOR, OR COMPRESSOR AND/OR PUMP)
The object of the invention is a motor or compressor and or pump which will transform into mechanical the utilizable part of potential energy and pressure of fluids (steam, gases, liquids) or vice versa, boost their pressure by an input of mechanical power thus providing for their delivery along a defined path.
Among the many types of motor known and used today our invention is still outstanding for its'varied applications, simple design, few components, wide-ranging output and torque, small weight coefficient, good mechanical efficiency, and simple regulation.
A particular advantage is that it operates without any valves, valve regulators, crankshaft and connecting rods, and no clutches and transmissions are needed because it has a high moment of inertia and the speed can be varied within wide limits.
The speed can be altered independently from the torque in a system where one device is working as a motor and the other as a pump by simply changing the pump speed, or by changing the volume of the steam or gas stream.
The torque may altered independently from the speed by changing the pressure in the input line.
The device is comparatively smaller than electric motors and i.e. engines. The sense of rotation may be varied by changing the sense of the input stream.
The general and typical design is shown in Figure 1. When the device is used as a motor, it will be connected to some source of power (1, 1/a) such as a heat exchanger, steam boiler, gas reactor etc. , or a pump or compressor, although it may be driven by some alternative form of energy such as the head between the levels of two water bodies.
The device consists of one or more units (2) shunted and/or connected in series. Each unit (2) features typically a pressure area (2/1) bordering on a rotor (2/2) and a stator (2/3). The rotor (2/2) communicates with the stator (2/3) over an appropriate length through at least one comparatively small slot. The axle (2/4) is fitted to the rotor (2/2). The input and output pressure zones are delimited by a partition (2/5) which is in moving contact with the rotor (2/6) and the stator (2/7) under the impact of force (2/8).
There is an inlet orifice (2/9) from the input pressure zone and an outlet orifice (2/10) into the output pressure zone. The units (2) are separated by the lid (2/11) of the pressure area consisting of hollow sections the lateral planes of which communicate with the rotor, the stator, and the partition by small slots, and enclose the axle: the lid may or may not be fixed to the axle, depending on the individual design.
The fluid coming in through the inlet orifice (2/9) will, after having compelled the rotor to rotate, exit through the outlet orifice (2/10).
If the device is operated as a pump or compressor, the rotor will press the fluid out through the outlet orifice. Figure 2 represents a variant with two or more units (2) connected in parallel or series. The arrow shows the sense of rotation for a connection in series where the fluid flows from the outlet (2/10) of each unit (2) to the inlet (2/9) of the next unit (2). The stator (2/3) encloses a cylindrical internal space which contains the pressure area (2/1), and the cylindrical rotor (2/2) with which it communicates through a small slot of appropriate length so that the rotor will evolve along the stator*s internal cylindrical jacket. The axle (2/4) is fitted to the rotor eccentrically. Two units (2) connected will be put at an angle of 180 , or three at an angle of 120 to one another, etc. Partition (2/5) is a prismatic body moving in the cavity (2/7) within the stator with a roller at its inner end pressed against the rotor through a spring (2/8). The lid (2/11) is a cylinder rotating with the rotor (2/2).
Figure 3a and 3b show a variant where two units are connected in parallel and two more in series: all the components are the same as described above for Figure 2.
Figure 4 shows a variant for which it is typical that the rotor has an irregular cylindrical form; it communicates with the stator as described above; and the axle is fitted to it concentrically. All the other components are the same as described above for Figure 2.
Figure 5 shows a variant for which it is typical that the stator (2/3) encloses a cylindrical internal space and the rotor (2/2) is cylindrical with the axle fitted concentrically. However, for some special application the functions of stator and rotor may be reversed by fixing the axle in which case the rotor becomes static (2/3a) and the stator (a cylinder jacket) will revolve around it (2/2a). There are two partitions:- one (2/5) in the cavity (2/7) within the central cylindrical piece (2/2, 2/3a), and the other (2/5a) in the outer circular piece (2/3, 2/2a). The second partition (2/5a) will only be used if and when the axle is fixed so that the rotor is stationary and acting as stator (2/3a) while the cylindrical jacket acts as rotor (2/2a).
If the inner cylindrical body (2/2,2/3a) acts as stator, the inlet and outlet orifices (2/9 and 2/10) will be made in this body, at the opposite sides of partition 2/5.
If the outer circular body (2/3,2/2a) acts as stator, the inlet and outlet orifices (2/9 and 2/10) will be located at the opposite sides of partition 2/5a.
Figure 6 shows a variant for which it is typical that two units (2) are put together i.e. two rotors are nested in one stator and either shunted or connected in series. The two cylindrical rotors (2/2) bounded by two planes and a convenient analytically described meridian plane are surrounded by the pressure area (2/1) and communicating through a convenient slot each with the cylindrical common stator (2/3). The axles (2/4) are concentric with the rotors, and there is one common partition (2/5) in a cavity (2/7) at the geometrical centre of the stator which contacts the two rotors simultaneously through the roller (2/6) and the stator through the sliding contact (2/7). The force (2/8) acting on the partition is provided by the two rotors which cause it to move as necessary. The inlet and outlet orifices are at the opposite sides of the partition. The plane bounds of the two units (2) and thus also the pressure areas are covered with a lid (2/11) which is a cylinder fitting in with the rotor (2/2), the stator (2/3), and the partition (2/5).
