US 2024/0295174 A1 · CONCENTRIC ROTARY MACHINE

Abstract

Disclosed herein is a concentric rotary machine including at least one chamber and at least one isolator (sliding port), which may be linear or rotary. In some embodiments, the isolator separates the chamber into two sub-chambers. In some embodiments, the machine includes a shaft and a piston, wherein the piston may be configured to rotate about the shaft's rotation axis, and wherein the piston includes a cavity for weight balance configuration and/or as a cooling mean. In other embodiments, isolator includes a receptacle (piston-passing opening) to allow for said piston to pass therethrough, and the isolator may include at least one extra cavity to avoid high pressures developed during the passing of the piston there through. In some embodiments, the machine includes a valve at the intake and/or outlet port, to control the amount of a working fluid.

Dependent claims

A rotary concentric machine comprising:

at least one shaft;
at least one piston that rotates on a circular orbit concentrically located with the at least one shaft;
a shell that forms at least one chamber, wherein the at least one piston is configured to rotate within the at least one chamber;
at least one isolator configured to separate the chamber into a plurality of sub-chambers;
and
at least one outlet port;
wherein the at least one piston has a linear velocity that is sufficiently high to insure that leakage of working medium from the at least one chamber to a neighboring chamber caused by a blow-by effect around a body of the at least one piston is less than 3% or the pressure loss is less than 3%.

4 more elements

A linear actuator comprising a plurality of sub-actuators including at least first and second linear sub-actuators, each of the first and second sub-actuators comprising an elongate body with a longitudinal axis and a piston or other member configured and arranged for periodically reciprocating along the longitudinal axis between an unextended position and an extended position, the first and second linear sub-actuators being connected in series such that (a) the respective drives of the first and second linear sub-actuators reciprocate between their respective unextended and extended positions at the same time and along the same longitudinal axis, and (b) a total length of extension of the first and second linear actuators comprises a sum of extension lengths of each of the first and second sub-actuators.
