  • pumps are fluid energy machines in which the energy inherent in the fluid is increased by applying mechanical labor. The pressure of the fluid medium is increased or it is given kinetic energy, often for the purpose of a change of location.
  • a conventional pump is usually only suitable for a few applications. Basically, a variety of fluid energy machines are known, they are used in different designs specifically for only a few applications. All fluid energy machines have in common that they should have a construction with the highest possible efficiency.

  • the principle of the fluid energy machine is that the fluid in the chamber (gap) between the inner circular rotary body and the inner bore (recess) of the outer housing is moved (pumped), with a barrier between the fluid inlet and outlet is provided. Against this barrier, a pressure is built up in the direction of rotation, wherein behind the lock in the direction of rotation, a vacuum builds up regardless of whether liquid or gaseous fluid media.
  • the blades are able to pass the barrier. For this purpose they must be retracted in the area of the lock in the groove (recess) of the rotary body rotation, so that they are sunk in the rotary body of rotation when passing the lock, after passing through the barrier, and reaching the fluid inlet they are extended again, this is done via a positive control in the outer body floor and lid, which is made as a circular and elliptical combined groove, which retract and extend the blade, in this case, the blade movement is converted into a linear movement during a rotational movement of the rotary body.

Un des deux paliers (34) à fixer l'un au-dessus de l'autre sur la pale (31) est utilisé pour sortir la pale (31) et l'autre palier (34) sert à rentrer la pale (31). Cela se fait grâce au pilotage forcé étagé (35) dans le fond de la carcasse (36) et le couvercle de la carcasse (36) et grâce au palier (25) qui est monté à rotation et dont le diamètre extérieur radial est plus petit que le diamètre intérieur radial de la carcasse. Il reste de ce fait entre le corps de rotation rotatif circulaire (24) et le diamètre intérieur de la carcasse (21) une chambre (fente) (28) dans laquelle le fluide arrive, entre dans la chambre (fente) (28) par l'entrée de fluide (29) et quitte de nouveau celle-ci dans le sens de rotation par la sortie de fluide (30).
