| 20090138125 | Environmental Control System - An environmental control system for conditioning air in a vehicle compartment, such as an aircraft cabin. Cool expanded higher-pressure air from a turbine is mixed with recirculated warmer, lower pressure air from the compartment. The air is mixed and recirculated by a jet pump which includes an inlet section, an outlet section, a diffuser section and a mixing section. The mixing section includes a plurality of separate mixing chambers. The diffuser section includes diffusers for receiving mixed gases from each of the mixing chambers. The outlet section receives the mixed gases which are then conveyed to the compartment. The inlet section includes for each of the mixing chambers, a primary nozzle for introducing the higher-pressure air into a respective mixing chamber, and a secondary nozzle for introducing the lower pressure air to a respective mixing chamber. | 05-28-2009 |
| 20090038688 | Fluid Control Valve - A fluid control valve for use in a system for inflating an anti-G garment. The valve includes an elongate chamber in which a valve member is moveable. The chamber has first and second axial ends. An inlet opening in a chamber wall provides for the flow of fluid into the chamber. A valve edge is provided at the second end of the chamber to form an outlet. The valve member has a first portion which closes the first chamber end and is moveable in the chamber between the inlet opening and the first chamber end, an intermediate portion which has a cross sectional area less than that of the chamber wall to permit the inflow of fluid to the chamber, and a second portion including a flow control device which co-operates with the valve edge to control fluid flow from the valve. | 02-12-2009 |
| 20090025811 | Hydraulic heating apparatus - A hydraulic heating apparatus includes a body having an inlet for high pressure fluid, and an outlet for heated fluid, a chamber within the body and a flow path for the high pressure fluid between the inlet and the chamber. The high pressure fluid flows through a restriction in the flow path between the inlet and the chamber whereby the apparatus becomes heated. The working fluid flowing from the inlet to the chamber must pass through an orifice which is closable by a linearly acting closure structure. The closure structure is urged to a position in which the closure structure closes the orifice when the pressure of the high pressure fluid is below a threshold pressure. The closure structure includes a thermally sensitive material which expands in response to increasing temperature to close the orifice in response to a temperature above a threshold temperature. | 01-29-2009 |
