Abstract
In one embodiment, a system includes a posimetric pump guide configured to mount in a port of a posimetric pump. The posimetric pump guide includes a first flow splitter defining first and second distribution channels into first and second passages in the posimetric pump. The first flow splitter includes a first pair of shroud walls spaced apart about a first disc opening. The posimetric pump guide also includes an abutment extending crosswise to the first flow splitter.
Claims20
A system, comprising:
- a solid fuel pump, comprising:
- a housing;
- a rotor disposed in the housing, wherein the rotor comprises a first disc coupled to a hub;
- a first curved passage disposed between the rotor and the housing on a first axial side of the first disc;
- a second curved passage disposed between the rotor and the housing on a second axial side of the first disc;
- a port extending through the housing to the first and second curved passages;
- and
- a solid fuel guide disposed in the port, wherein the solid fuel guide is fixed relative to the housing, the solid fuel guide comprises a first flow splitter that splits the port into first and second distribution channels leading into the first and second curved passages, and the first flow splitter overlaps the first axial side or the second axial side of the first disc.
