Systems, methods, and devices relating to a mechanism which can be used in gas cooling devices, pneumatic motors, turbines and other pressurized gas devices. A rotatable rotor is provided along with a number of hollow conduits that radially radiate from an exit port at the center of the rotor. The pressurized gas is injected into the mechanism at the inlet port(s). The gas enters the conduits and travels from the inlet port(s) to the exit port(s). In doing so, the gas causes the rotor to rotate about its central axis while the gas cools. This results in a colder gas at the exit port(s) than at the inlet port(s) due to an enhanced extraction of work, while maintaining a very low flow rate at the cold outlet.

Mechanism for enhanced energy extraction and cooling of pressurized gas at low flow rates

An apparatus for providing flushing fluid at different rates has a valve for controlling flow through a housing, the valve having a reset area to close the valve, a first bleed valve for constantly providing high pressure fluid to the reset area through a first path, a second bleed valve for providing high pressure fluid to the reset area through a second path, and an actuator. The actuator has a first position in which fluid is prevented from escaping from the second path, a second position in which fluid is allowed to escape from the second path and the second bleed valve is activated, and a third position in which fluid is allowed to escape from the second path and the second bleed valve is deactivated. If the second bleed valve is activated, the first bleed valve causes the reset area to close the valve in a first time period and if the second bleed valve is not activated the first and second valves cause the reset area to close the valve in a second time period wherein the second time period is less than the first time period.
