SCROLL-TYPE POSITIVE FLUID DISPLACEMENT APPARATUS

A positive fluid displacement apparatus employing scroll members having interfitting spiroidal wraps angularly and radially offset such that as the spiral centers experience an orbiting motion, they define one or more moving fluid pockets of variable volume. The zones of lowest and highest pressures are connected to fluid ports. Radial sealing is accomplished with minimum wear by using a driving mechanism which provides a centripetal radial force adapted to oppose a fraction of the centrifugal acting on the orbiting scroll member. The line contact sealing force between the wraps of the scroll members constitutes the sole radial constraining force. Coupling means which are separate from the driving means, and hence from the radial constraining means, are provided to maintain the desired angular relationship between scroll members. Axial sealing is attained by withdrawing a portion of fluid from the zone of highest pressure and using this high-pressure fluid to generate axial sealing forces ...

Scroll compressor with closed compression spaces having valves to reduce starting torque

A scroll compressor comprises an orbiting scroll and a fixed scroll, each of which includes a spiral wrap. These orbiting and fixed scrolls define between their wraps a plurality of close spaces at symmetrical positions. These closed spaces are moved toward the center of the scrolls by means of orbital motion of the orbiting scroll relative to the fixed scroll for reducing their capacities to compress fluid confined therein. Upon starting the compressor, some of the spaces which are in mid course of compressing and the other closed spaces which locate at the downstream side just before the communication with a discharge port, are communicated with each other through valves which open when pressure in the closed spaces at the upstream side is higher than that in the closed spaces at the downstream side, whereby a loading torque upon starting is decreased.

Spiral compressor

Using spiral compressors for compressible media and liquids, which compressors have a wrapping angle of at most approximately 540 DEG , only a relatively low compression pressure can be achieved. In the case of spiral compressors whose generator poles associated with the individual spiral courses are at a distance from one another, considerable torques are exerted on the compressors. So as to largely eliminate said torques and to increase the compression pressure, it is proposed according to the invention to design a spiral compressor in such a way that at least two intermeshing external spiral-shaped pumping ducts, which have a wrapping angle of at least 360 DEG , communicate with at least one internal spiral-shaped pumping duct having a wrapping angle of at least 360 DEG . ...

METHOD AND DEVICE FOR GENERATING ENERGY BY USING WIND POWER

Wind driven power generator - has rotor within casing profiled to increase air velocity to utilise low wind speeds

The generator has a casing which can be rotated about a vertical axis to bring it into the wind. Within the casing there is a rotor (2) which carries aerodynamically profiled axial flow blades (1). The inner surface of the casing is profiled so that the cross section of flow reduces from the inlet (5) to the leading edge (4) of the blades (4). The air velocity is thus increased and the generator operates satisfactorily at very low inlet wind velocities. The pitch of the blades can be varied. The rotor and casing are profiled (7,8) so that this variation does not produce a gap round the blades.

Apparatus for converting solar energy to air flow

Propeller arrangement, in particular for ship propulsion plants

Conventional propellers are borne on a hub bearing in their centre. The axial forces acting on the blade tips (3) in particular subject the blades (7) to a large bending moment. Therefore, the blades have to be of very massive construction, which however increases the stresses on the propeller due to centrifugal forces. So the size of such propellers is limited. Furthermore, the cost of the materials for manufacturing conventional propellers is comparatively high. In order to overcome these disadvantages, it is proposed that a propeller (2) equipped with an outer ring (4) be mounted, together with this outer ring (4), in a housing (5), so that a hub bearing can be dispensed with. The axial bending moments acting on the blades (7) of the propeller (2) are reduced, so the blades (7) can be made lighter. The centrifugal forces thus reduced also make larger propeller diameters possible than in the current state of the art. The propeller arrangement (1) can be utilised for ship propulsion and wind generators. <IMAGE>

Means to regulate water velocity through a hydro electric turbine

A hydro electric turbine having a flexible, collapsible front shroud, the upstream open end of the front shroud being controlled by a draw line passing through purse rings, whereby the upstream end can be closed by drawing on the draw line, thereby stopping water flow through the turbine. Decreased drag allows the turbine to rise to the surface. Opening the upstream end so that water flows into the turbine increases drag to lower the turbine into the water and causes rotation of the turbine blades.

Further independent claims are directed at: - the bearing arrangement of the turbines comprising a radical bearing arrangement comprising magnetic repulsion bearings and a thrust bearing arrangement comprising a series of axially sequential thrust bearing surfaces. - a transmission between turbine and generator which may be torroidal.

Structure for concentrating wind energy

The invention belongs to the field of wind power systems. The proposed funnel-like constructions can collect wind energy from a large area and concentrate it to a smaller area and increase the velocity of the wind before it drives the propeller, the rotor or the turbine. The patent claims are in respect of the use of inflatable or fillable or combined inflatable/fillable funnel-like constructions for concentration of wind power and increasing wind velocity in wind power systems. The wind (1) is concentrated by the funnel-like construction (2) and passes the propeller, the rotor or the turbine (3) at greater velocity. The technical problem of reducing the costs of wind power systems is resolved by the use of air, water, sand etc. as a building material in simple fashion and by the scaling-down of the dimensions of the propeller, the rotor or the turbine as a result of concentrating the wind. The technical problem of eliminating negative environmental effects of wind power systems is resolved by the funnel-like construction encapsulating the propeller, the rotor or the turbine. The principal application of the invention is in wind power systems.
