Abstract

A vane pump including a movable sleeve disposed between the casing and the rotor vanes in which axial and angular movement of the sleeve enables control of the fluid flow.

Description

  • The invention belongs to the domain of positive displacement machines for liquids with rotating cylinders F 04 B 1/10 and positive displacement machines for liquids F 04 C 2/22.
  • The core of the invention is to put a movable sleeve into a vane pump, which enables regulation of the fluid flow.
  • FIG. 1 is partial cut view drawing of the pump
  • FIG. 2 represents various arcs in the pump
  • FIG. 3 represents compensation of various arcs in the pump
    •
  • Pump can be used in all applications where variable fluid flow is required
  • Pump (FIG. 1) comprises of casing (1), rotor with vanes and shaft (2), movable sleeve (3), two lids (4), two end stops (5) and two supports (6 and 7).
  • Movable sleeve (3) has two apertures (a) and two circulation channels (b) which may be either in the casing (1) or partially in the casing (1) and partially in the sleeve (3). Since it is obvious that the arcs (m and n) are unequal (FIG. 2) it is necessary to overcome this disparity in the moment when vanes are approaching the aperture (a). Solution to this problem is obtained by one end of each aperture being slanted (FIG. 3). When the sleeve moves axially, the vanes will reach the aperture (a) earlier or later. The apertures (2) have the opposite ends slanted.
  • Axial movement of the sleeve (3) results from guidance of the inclined surface on support (6).
  • Sleeve (3) can move angularly (arcuately) to change the fluid flow. Regardless of the rotational direction of the rotor, by turning the sleeve for the full circle (in any direction) the fluid flow is changed from zero to maximum in one direction and then through zero to maximum in the opposite direction and finally to zero again.
  • Rotor (excluding vanes) should not touch the sleeve.

Claims (4)

1. A vane pump comprising:
a casing;
a rotor disposed in said casing, said rotor including vanes; and
a sleeve disposed about said rotor and movably within said casing, said sleeve including a plurality of circulation channels and a plurality of apertures, said apertures having their ends slanted relative to said vanes.
2. A vane pump as set forth in claim 1 wherein a plurality of end stops abut said rotor.
3. A vane pump as set forth in claim 1 wherein a plurality of supports abut said rotor.
4. A vane pump, comprising a casing, a rotor with vanes and shaft, two lids, two end stops, two supports, and a sleeve disposed about said rotor and within said casing, said sleeve and said casing together defining a plurality of circulation channels therebetween, said casing having a plurality of apertures, said apertures having slanted ends, said sleeve being movable relative to said casing to place said ends of said apertures in variable relation to said circulation channels.
