| 52 | Expansion or compression machine with interengaging members rotating on perpendicular axes | US12462 | 1979-02-15 | US4285644A | 1981-08-25 | Kauko A. Takalo |
| A machine of positive displacement type for the expansion or compression of elastic fluids, wherein torque created or applied effects directly the power shaft, bearings of the power shaft are loaded only by weights of corresponding rotary masses, sealing lubrication is not used and the structure of the machine should accountably facilitate achieving of low losses.The machine includes working spaces (5) defined by a rotary working member (1) and a surrounding body structure (4), and moving circumferentially with the working member, their main direction joining with said circumferential direction. The working spaces (5) are divided into a process space (6) and a transferring space (7) by a partition wall (15) belonging to rotary non-working reacting members (8) which are perpendicular to the working member and synchronized therewith and of so firm structure that they can transmit to the outside of the working member great forces due to a pressure difference between said spaces (6, 7). Said forces can be compensated by a programmed pressure effect onto a counter-surface (11) of the reacting member. Depending on the direction of rotation of the working member either expansion or compression of elastic fluid circulating through the machine is performed. Rotary valves (23) are preferably used for achieving a cyclic closing of the process space (6). A momentary area of the valve opening can essentially correspond to a momentary area of the partition wall (15). A partition wall forming part (10) of the reacting member is preferably provided with only one transition sector (77) for changing the process cycle, where requirements as to synchronization are low. Light sealing members (110) are preferably used to reduce remaining loss effects due to error in synchronization. Clearances not depending on synchronization may be maintained small by using temperature control of respective parts. A major part of the clearances can be provided with a labyrinth seal (61, 103, 104) for reducing the speed of gas leak. | ||||||

| This rotary engine performs the same four phases as any other piston and rotary engine. Yet, unlike other engines this one has no crankshaft. It consists of a circular housing in which a circular rotor revolves slightly off center in relation to its housing.The rotor carries through its cavity vanes (or blades) that are kept continuously close to the housing by the centrifugal force as the rotor turns. The vanes never touch the housing, they are kept at a safe distance by a ring which is guided by a ball bearing. To make the contact gas-tight each vane is tipped with an inset metal strip.The rotor with its vanes rotating in its housing develops two expanding-contracting chambers, one inside it and the other peripheral to the housing.The inside chamber is to intake the mixture and pump it into the peripheral or combustion chamber, this will decrease in volume compressing the mixture, as the rotor edges by the spark plug the fuel-air mixture is ignited, the exploding gas pushes the rotor in its circular motion.All the while the inside chamber continues its intake of fresh mixture and pumps it into the combustion chamber.The cycle is then repeated. | ||||||

| Vane type rotary combustion engine in combination with a compressor apparatus for supplying a charge of air or an air-fuel mixture to the engine. The engine and compressor are drivingly connected to each other and include a conduit connecting the compressed charge outlet of the compressor to the intake port of the engine so that a compressed charge may be led into the engine. The engine includes a rotary-vane assembly wherein a series of rotatable chambers are provided therein, with a rotatablecombustion chamber of relatively low volume rotating past the intake port. A timed valve closes the intake port after which ignition of the charge in the combustion chamber takes place and effects a power stroke against a rotary-slide vane. A continuous succession of power strokes are effected by successive rotary combustion chambers formed by rotary-slide vanes. | ||||||

| An internal combustion engine of the rotary type which includes a cylindrical rotor having a skirt portion, rotating in an annular chamber, that comprises two arcuate walls of differing radii joined by relatively short, diametrically disposed sloping portions that serve as pistons. A sliding divider which extends through the annular chamber and the skirt portion establishes, with the sloping skirt portions, sub-chambers in the annular chamber in which compression of a combustible gas mixture and combustion of the mixture take place, the latter producing power for moving the rotor and the power shaft attached thereto. The divider is provided with longitudinallly spaced slots in which the rotor skirt is engaged whereby the divider is reciprocated as the sloping portions of the skirt pass through the slots. | ||||||
