Definitions

  • the present invention relates to the mechanical field and proposes in particular, a rotary device for use in engine, compressor, pump or more generally to allow the transfer of fluid (gas or liquid) and driving a load.
  • the driving of a load is currently carried out by reciprocating piston type engines.
  • This training has a yield and a mean rate before failure also called "MTBF" (Mean Time Between Failure) substantially low.
  • the present invention aims to overcome these disadvantages of the prior art by providing a rotary device to minimize the number of moving mechanical parts and to ensure a high efficiency motor.
  • the piston is in the form of a cam and positioned inside a cylinder of cylindrical shape, the device comprising two lateral inlets serving as feed ports for the cylinder and two front outlets serving as escapement housed in said piston.
  • the piston pivots and drives an axis, two side segments and a front segment being provided to provide a seal on the upper part of said piston.
  • the two flanges are provided on either side of the piston and allow maintenance of the rotating piston-pin assembly.
  • the two flanges comprise the location of two bearings on which the axis is fixed and are also provided with two segments of different diameters, inserted into two inner and outer grooves of a feed channel.
  • the feed channel is formed on a working sector according to the curvature of the piston and a buffer sector made by a segment in order to stop the supply during the dead time.
  • Another purpose is achieved by proposing a use of the device characterized in that during a use of engine type operation, the device allows to drive a load and during a use of compressor type operation or pump, the device allows the transfer of fluid (liquid or gas).
  • the supply of pressurized gas or liquid from a feed chamber of the cylinder allows the rotation of the piston about the axis, this rotation allowing to empty of its contents an exhaust chamber of the cylinder through an exhaust port.
  • a suction effect is created by a supply port (4) during the rotation of the piston (2) which delivers gas or liquid through the exhaust port (5).
  • the device according to the invention makes it possible, on the one hand, to considerably improve the efficiency and the engine torque available from the beginning of the power supply of the device and, on the other hand, to set in motion a very small number of parts. which ensures an excellent average failure rate (MTBF).
  • MTBF average failure rate
  • a fluid or a gas under pressure is injected through at least one supply port (4) of a cylinder block (1).
  • This gas or fluid passes through feed channels (14) through the cylinder block (1), then through channels flanges (17, 17 ') and finally through channels through a piston (2) in the form of cam.
  • This gas or fluid as a function of its pressure determines the available engine torque.
  • This piston (2) mounted in free rotation along an axis or transmission shaft (3) and inside the cylinder block (1), pivots about the axis (3) as a function of the flow rate and the pressure of the gas or fluid in the chamber (10) of the cylinder block (1) so as to empty its contents an exhaust chamber (11) of the cylinder block (1) by an orifice (5) exhaust.
  • a kinetic flywheel (20) is disposed at one end of the transmission shaft (3) and makes it possible to store the kinetic energy.
  • the device When using the device in compressor or pump operation, the device is driven mechanically on the transmission shaft (3).
  • the transmission shaft (3) rotates the piston (2).
  • a suction effect is created at the supply orifice (4) and during the same operating cycle of the device, the piston (2) delivers the gas or the liquid to empty the exhaust chamber (11) from its contents through the exhaust port (5).
  • the device comprises a rotary piston (2) for transforming a gaseous or liquid force into a mechanical force.
  • This cam-shaped piston (2) is located inside the cylinder or cylinder block (1) of cylindrical shape and axis (3) and is rotatably connected to the transmission shaft (3) so as to pivot about said axis (3).
  • On the cylinder (1) of cylindrical shape and axis (3) is provided the separator drawer (6) which provides the seal between the supply and the exhaust.
  • the device comprises two lateral entrances or supply ports (4) for feeding the cylinder (1) and two front outlets or exhaust ports (5) housed in said piston (2). Two side segments and a front segment (7) are provided to seal on the upper part of the piston (2).
  • the cylinder block (1) is provided with a housing (19) itself composed of the separator or drawbar drawer (6), two springs (15), three segments (16) and a feed inlet.
  • Two flanges (17, 17 ') are provided on either side of the piston (2) to allow a maintenance of the entire axis (3) - piston (2).
  • the two flanges (17, 17 ') comprise the space necessary to receive respectively two bearings in which the axis (3) is introduced and fixed so as to keep the piston (2) in rotation, the two bearings being maintained respectively by two small flasks or "flasks" (18, 18 ').
  • the two flanges (17, 17 ') are also provided with two circular shaped grooves in which two segments (8, 9) of different diameters are housed there to ensure the radial seal of the device.
  • the two circular shaped grooves are located on the inner and outer surfaces of a feed channel (12).
  • the supply channel (12) of the cylinder (1) is provided on a sector defined by the size and shape of the piston (2).
  • the feed channel (12) is formed on a working sector according to the curvature of the piston (2) and a buffer sector made by a segment in order to stop the supply during the operating dead time of the device.
  • the supply of the device is provided by the supply channels (14) of the cylinder block (1) which are connected to the supply port (4) located on the outer surface of the cylinder block (1).
  • the exhaust is made during the rotation of the piston (2) by the side outlets or exhaust ports (5).
  • One of the advantages of the invention is that the device makes it possible to considerably improve the efficiency and the motor torque available from the beginning of the power supply of the device and to set in motion a very small number of parts which ensures an average rate before failure (MTBF) excellent.
  • MTBF average rate before failure
