Definitions

  • the pressure increase is achieved according to the prior art in different ways, to which reference is made to the known external gear pumps, internal gear pumps and vane pumps.
  • vane pumps is usually provided that the receiving space for the rotor in the suction has a radial bulge, which allows the locking elements (vanes) can further extend from a rotor of the rotor, thereby increasing the volume of the working cells in this Enlarged area.
  • the bulge decreases or disappears, so that the blocking elements (vanes) are pushed back into the rotor and the volume of the working cells is correspondingly reduced, resulting in an increase in pressure.
  • Figure 1 is a simplified representation of a cross section through a two-stroke
  • the axial height that is to say the axial height, that is to say the axial height.
  • H the depth of the housing bore, in the pressure range is "h”
  • the maximum depth of the housing bore in the suction region is "h + x"
  • x represents the maximum additional recess 11.
  • a value of 8 to 12 mm, preferably 10 mm, is provided for "h”

Abstract

L'invention concerne une pompe refoulante, en particulier pour transporter du carburant, qui présente un induit (1) monté dans un boîtier (2). Le boîtier (2) entoure l'induit (1) au moins radialement. Deux parois frontales (3, 4) adjacentes frontalement à l'induit (1) sont prévues de manière à former un espace de réception (5) pour l'induit (1). Un conduit d'amenée et un conduit d'évacuation (9, 10) sont en outre prévus pour l'espace de réception (5). L'induit (1) est doté de plusieurs éléments de blocage (7) qui s'étendent radialement vers l'extérieur depuis l'axe de rotation (6) de l'induit (1). En même temps que les parois frontales (3, 4) et le boîtier (2), les éléments de blocage (7) forment une pluralité de cellules de travail (8) mutuellement adjacentes pour le transport d'un fluide. Partant de la zone d'aspiration qui correspond au conduit d'amenée (9), l'extension axiale de l'espace de réception (5) se rétrécit en direction de la zone sous pression qui correspond au conduit d'évacuation (10) associé. Les éléments de blocage (7) sont configurés de manière à pouvoir compenser les modifications axiales de la section transversale de l'espace de réception (5).
