摘要:
A multiple vane kinetic system that produces variation in enclosed volumes between pairs of radial vane sets independent of each other and coaxial with a central axis within a annular casing that encapsulates the vane sets and operates in a sequence where the vane sets function as rotating links of the mechanism for a pellicular period, which is preceeded and succeeded by another period where either vane sets successively alternate between being a fixed link and a rotating link of the mechanism and during the former period the volumes between vanes remain constant as long as the vane sets have equal angular velocities, otherwise varies at rates proportional to differing angular velocities. The two time periods are controlled by timing devices actuating the vane sets to be coupled and decoupled with a power shaft and the variation in length of the two time periods makes roto-dynamic variable displacement machine.

Heat engine comprising a body (2) provided with an annular cavity (3) therein, two coaxial discoidal sectors (7, 7′) that comprises two diametrically opposite tangential pistons (7a and 7c or 7′b and 7′d) that project, both radially and axially, from their corresponding discoidal sector and can slide through the annular cavity, each pair of consecutive pistons defining a chamber (Cab, Cbc, Ccd, Cda), a means of control of the rotational speed of the two discoidal sectors that makes their respective rotational speeds to vary cyclically and in antiphase between a maximum speed and a minimum speed, so that the speed of each sector is kept at a substantial maximum for most of the duration of a half-cycle, and is kept at a substantial minimum for most of the duration of the other half-cycle, and a means (8) of integration of the speeds of the sectors into a mean speed for the power transmission shaft (9).

A dveljagimmal device (1) serving as a control mechanism and a gearing suitable for use in conjunction with a rotary machine of the "cat and mouse" type. The device (1) comprises a stationary housing (2) from which extends a first (3) and second (4) shaft, the shafts (3,4) being coaxial. The device (1) is characterized in that the second shaft (4) terminates in a frame (5) which rotates in company with rotation of the second shaft (4). The device (1) further comprises a first (6) and a second (7) annular bevel gear, which first (6) and second (7) annular bevel gears are fixedly mounted to the housing (2), are coaxially aligned with the first (3) and the second (4) shafts, and are spaced apart allowing the frame (5) to be freely rotatable therebetween. A first (8) and second (9) pinion gear are basically mounted in the frame (5) with an axis of rotation offset from the perpendicular to the common axis of the first (3) and second (4) shafts, such that the first pinion gear (8) is in engagement with the first annular bevel gear (6) only and the second pinion gear (9) is in engagement with the second annular bevel gear (7) only. When the second shaft (4) and the frame (5) rotate, the first (8) and second (9) pinions are in engagement with their respective annular bevel gear (6,7) and rotate in the same direction, there being a gimmal (10) mounted in the frame (5) between the pinion gears (8,9) in engagement with the first shaft (3) to cause an irregular motion and period of dwell in the motion of the first shaft.

A rotary engine includes a pair of rotors each supporting opposed toroidal section pistons rotatably disposed within a crank case defining a toroidal combustion chamber. The piston rotors define pluralities of curved slots which receive interconnecting coupling pins. A drive cam cooperates with the drive pins and a slotted pin guide is captivated between the drive cam and one of the slotted piston rotors. The cooperation of the pin guide, cam and slotted rotors provides the required piston motion and power coupling for use as a rotary engine for rotary pump or compressor.

A rotary engine has a first ring-shaped floor portion connected to an inner shaft for rotation therewith and a second ring-shaped floor portion connected to an outer shaft for rotation therewith. The annular floor portions cooperate with an engine casing to define an annular chamber. A first pair of diametrically aligned pistons are positioned within the annular chamber and are connected to the first ring-shaped floor portion while a second pair of diametrically aligned pistons are positioned within the angular chamber and connected to the second ring-shaped floor portion. The pistons cooperate to define a plurality of combustion chambers. Means are provided for causing combustion in the combustion chambers for imparting rotary motion to the inner and outer shafts. A first power transfer gear connected to the inner shaft transfers power to a drive shaft when the inner shaft is driven and a second power transfer gear connected to the outer shaft transfers power to the drive shaft when the outer shaft is driven. Unique piston seals, a controller for regulating the position of the pistons, and a novel lubrication system are also disclosed.

A hydraulic device comprises a rotary toroidal piston chamber having a rectangular space with a bottom, two sidewalls, and an open top. Four stationary pistons and two retractable gates for each piston are within the toroidal chamber mounted on a chamber wheel fixed to an axle on which it rotates, wherein the pistons and the gates are evenly spaced around the toroidal chamber separating the chamber into four partitions. A piston support for each piston is configured to hold the piston stationary while the piston chamber rotates. A stationary cover encircles and seals the open top of the piston chamber wherein openings through the stationary cover allow each of the piston supports to pass through and be sealed. An input port opening and an output port opening are in the stationary cover for each partition. The piston chamber rotates by reacting directly to continuous hydraulic force on the stationary pistons.
摘要:
Axially protruding and centrally cool able pistons rotate within a cylindrical main chamber. Each piston is individually kinetically linked to a flywheel. As the pistons are individually accelerated and decelerated along their continuous rotating path, rotating volumes between them angularly expand and contract. Such rotating piston mechanism may be part of compression and/or expansion stages of a combustions engine system that may further feature a combustion system and/or a particle fuel evaporator in between them in which solid fuel particles are heated such that their evaporable portion evaporates to be used as engine fuel. Absence of valves and self cleaning centrifugal effects in the rotating volumes of the compression and/or expansion stages are thereby advantageously utilized to combust solid particle fuel and/or their evaporating content with low risk of particle clogging or built up. Remaining carbon particles may be extracted from the combustion engine via a carbon particle extraction port.
摘要:
A reciprocating part free kinematic apparatus, designed for transforming the volume variations of a plurality of chambers into a rotary motion of an axis, is characterized in that all the mechanism for performing this function is housed in a cylindric cavity coaxial with the driving axis, between the cylindric cavity, a smaller diameter inner coaxial cylinder and two discs perpendicular to the axis, being defined a toroidal cavity in which are housed rotary pistons, each longitudinally traversed by an axis and having a cross-section schematically in the shape of a circular sector, said rotary pistons rotating so as to cause the cavities defined therebetween, also of a substantially circular sector shape cross section, to cyclically change their volumes.This variation, controlled by a mechanism including a cam, the axes passing through the pistons and suitably arranged connecting rods, provides a fluid working cycle causing the driving shaft to rotate through a mechanism including a connecting rod and related crank system.Accordingly, the disclosed kinematic motion apparatus can be used both for transforming the expansion of the pressurized fluid into a mechanical work available on an axis, and to transform the mechanical work into a potential energy, by transforming it to a fluid through a compression operation.
