Abstract: A heat exchange system includes a cold fluid circuit and a hot fluid circuit. The cold fluid circuit routes a cold fluid to a ram air inlet. From the ram air inlet, the cold fluid is routed to a cold fluid inlet of a heat exchanger. The cold fluid is then routed to a cold fluid outlet of the heat exchanger. The hot fluid circuit is configured to route a hot fluid. The hot fluid is routed through a bleed air valve. From the bleed air valve, the hot fluid is routed to a hot fluid inlet of the heat exchanger. The hot fluid is then routed to a hot fluid outlet of the heat exchanger. The hot fluid is then routed to a header having a first cavity and a second cavity defined within a housing and separated by a baffle.

Abstract: A four-way distribution valve is provided that allows for efficient filling and drainage of a potable water supply and waste system including a potable water distribution manifold and water filter in a commercial aircraft galley. The water distribution valve includes a cruciform manifold having a filter drain port connected to the water filter, two supply manifold ports connected to the potable water distribution manifold, and a drainage discharge port. A rotary closure element within the cruciform manifold actuates in accordance with four selectable filling and discharge modes for the valve to fill and drain potable water in the potable water supply and waste system. As a result, the valve can be used to fill the potable water supply system with potable water before a flight, and to selectively drain potable water from the potable water distribution manifold, the water filter, or both after a flight, all through the same valve.

Advantageously, the body (2) comprises an inner cylindrical housing (4) having a circular cross-section, and the closure means (3) comprises one portion (14) arranged on a plane inclined in relation to the cylindrical housing (4) and co-operating with the side wall (5) of the housing by means of a peripheral generatrix, such as to provide a sealed contact between the closure means (3) and the body (2) in at least one angular position.

Abstract: The invention relates to a fluid circulation valve comprising a body (2) through which said fluid can pass, and a first and second shutoff means (3, 3?), arranged in series, in the direction of flow of the fluid, in said body and each able, by rotation of said means (3, 3?) with respect to said body (2) to occupy various angular positions, said valve further comprising a drive train allowing said shutoff means (3, 3?) to be driven off one and the same actuating motor, said valve being configured to: —over a first angular range of said first shutoff means (3) allow said fluid to be metered in a first outlet port (40) of said valve, said second shutoff means (3?) being in a position in which said first port (40) is wide open, —over a second angular range of said first shutoff means (3) allow said fluid to be metered in a second outlet port (42) of said valve, said second shutoff means (3?) being in a second position in which said second port (40) is wide open.

Abstract: A damper for controlling fluid flow includes a main body, a stator and a rotor. The stator may be carried by the main body and include at least one blade having a predetermined shape. The rotor may be moveably connected to the stator and carried by the main body. The rotor may include at least one blade having a predetermined shape and may be moveable between an opened position and a closed position. The predetermined shape of the at least one stator blade and the at least one rotor blade may form a converging-diverging nozzle, and the stator and the rotor may be carried by the main body so that fluid flows through the main body substantially perpendicular thereto. The opened position may be defined as the at least one stator blade being aligned with the at least one rotor blade, and the closed position may be defined as the at least one stator blade being offset from the at least one rotor blade.

Abstract: A turbocharger wastegate valve assembly comprises a first bypass port communicating with a first portion of an exhaust inlet and a first valve member adapted for engaging and sealing a first valve seat surrounding the first bypass port. The valve assembly further comprises a second bypass port communicating with a second portion of an exhaust inlet and a second valve member adapted for engaging and sealing a second valve seat surrounding the second port. A shaft supports each valve member for rotation about a shaft axis to lift both the first and second valve members from sealing engagement with the first and second valve seats respectively. The first valve seat is inclined relative to the second valve seat and the shaft has freedom of movement in the axial direction.

Abstract: An improved one-way fluid valve construction is provided. A valve housing (102) includes one or more valve ports (108) and control ports (110). A control member (304) is disposed within the control port (110). The control member (304) is movable within the control port (110) between a first position and a second position. A control rod (302) can extend between the control member (304) and a portion of the valve port (108). A control rod coupling (402) interacts with the control member (304) to cause a rotational or pivotal movement the control rod (302) through a predetermined angular arc in response to movement of the control member (304). A sealing face (404) formed on a second portion of the control rod (302) advantageously forms a seal with an orifice (316) that separates an input side of the valve port (108) from an output side. The seal can be formed when the control rod (302) is in a control rod sealed position.

An indexable drive rotates the rotatable head to interconnect predetermined primary channels and secondary ports. The timing of rotation can be continuous or intermittent depending upon the associated process of the fluid streams.
