Compressor, engine or pump with a piston translating along a circular path |
| 摘要 |
Described herein is a device comprising: a chamber wall comprising outer and inner surfaces, wherein the inner surface encloses a lobed chamber with a plurality of lobes and the inner surface comprises segments of arcuate surfaces, each of the segments of arcuate surfaces being tangent with its immediate neighboring segments, and wherein the chamber wall further comprises channels connecting the outer surface and the inner surface of the chamber wall and/or channels through an end surface of the chamber wall; a lobed piston configured to translate along a circular path relative to the chamber wall, the outer surface of the piston and the inner surface of the chamber wall engaged during translation; and holes fluidly connected to the lobed chamber and configured to allow fluid discharge from the lobed chamber through the holes and to prevent fluid flow into the lobed chamber through the holes. |

1. A device comprising:
a chamber wall comprising an outer surface and an inner surface, wherein the inner surface encloses a lobed chamber with a plurality of lobes and the inner surface comprises segments of arcuate surfaces, each of the segments of arcuate surfaces being tangent with its immediate neighboring segments, and wherein the chamber wall further comprises channels connecting the outer surface and the inner surface of the chamber wall and/or channels through an end surface of the chamber wall; a piston configured to translate along a circular path relative to the chamber wall and form enclosed spaces between the piston and the chamber wall; and holes fluidly connected to the lobed chamber and configured to allow fluid discharge from the lobed chamber through the holes and to prevent fluid flow into the lobed chamber through the holes; wherein the piston comprises an outer surface enclosing a main body of the piston, the main body having a plurality of lobes located in the lobes of the lobed chamber, the outer surface of the piston and the inner surface of the chamber wall engaged during translation and forming a fluid-tight seal between some portions of the outer surface of the piston and the inner surface of the chamber wall; wherein the main body of the piston and the lobed chamber have a same number of lobes. |
