An apparatus includes a gas turbine engine flow device having an inner member and a surrounding member. The inner member has a first coefficient of thermal expansion; and the surrounding member at least partially surrounds the inner member and has a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. The surrounding member includes at least two walls that form a variable flow gap therebetween. The inner member is oriented relative to the at least two walls of the surrounding member such that, based on the difference in the first and second coefficients of thermal expansion, the inner member expands relatively greater than the surrounding member or the surrounding member expands relatively greater than the inner member, according to a temperature change to correspondingly enlarge or reduce the size of the variable flow gap between the at least two walls.

A valve can be incorporated as an integral part of the heat exchanger as a plug-in item that can be located anywhere desired between the inlet and outlet flow manifolds of the heat exchanger.

A temperature adjustment device is capable of suppressing sleeve enlargement and preventing the rattling thereof with a synthetic resin housing. Flanges are formed on the temperature adjustment member. The sleeve has a groove along the circumferential direction on its outer periphery and a lateral hole opening at one end to the groove and penetrating through the wall thickness of the sleeve. A clip member has an outer fitting portion, elastically deformable and fittable to the groove and has an inward convex portion holding the flange from the distal-end side of the sleeve, by being inserted in the lateral hole. The groove wall has a groove-depth wall at the deepest portion opposite to the groove opening and a distal-proximal-end-side curved portion of the groove-depth wall connected to the distal-proximal-end side of the sleeve. The radius of curvature of the distal-end-side curved portion is larger than that of the proximal-end-side curved portion.

The liquid cooling system has a heat exchanger having a fluid inlet and an outlet; a fluid supply conduit leading to the inlet of the heat exchanger; a fluid return conduit extending from the outlet of the heat exchanger; a bypass conduit extending between the fluid supply conduit and the fluid return conduit; a thermal valve configured for selectively closing the bypass conduit, the valve having a temperature sensing element positioned downstream of both the heat exchanger and the bypass conduit, the temperature sensing element configured to selectively move the thermal valve in response to a temperature change of the liquid which the temperature sensing element is exposed to relative to a temperature threshold of the valve; and a deflector positioned between the temperature sensing element and at least one of the bypass conduit and the heat exchanger outlet.

The invention relates to valves including housing and a thermostatic element, including a fixed portion and a mobile portion. A first plug is axially movable relative to a first seat in order to control the flow of fluid between first and second paths and is carried by the mobile portion in such a way that it moves the first plug by causing it to remain in the closed configuration when deployed below a predetermined stroke and to move to an open configuration when deployed beyond that stroke. A second plug is axially movable relative to a second seat in order to control the flow of fluid between the first and a third path and is carried by the mobile portion in such a way that it moves the second plug from the closed configuration to the open configuration when deployed below the predetermined stroke.

Provided are anti-scald assemblies for a faucet housing having a polymeric manifold housing with an anti-scald cavity housing an anti-scald device, a mixing cavity housing a mixing valve, and an actuator cavity housing an actuating member. A longitudinal axis of the anti-scald cavity is at an angle between 0 and 90 degrees relative to a longitudinal axis of the actuator cavity. The anti-scald device comprises a thermal actuator coupled to a plunger, and the thermal actuator and the plunger are held in an open position within the anti-scald cavity with a bias spring. When the temperature of the mixed water reaches a pre-set temperature in the sensing region of the anti-scald cavity, the thermal actuator is configured to expand such that the thermal actuator moves the plunger of the anti-scald device along the longitudinal axis of the anti-scald cavity to a closed position to close off the hot water inlet.

A thermostatic control device according to the present disclosure is configured to control the flow of coolant fluid from a reservoir through a heat exchanging circuit and/or a bypass back to a cooling circuit pump. The device controls the flow of coolant fluid based on temperature of the coolant fluid at the device. The thermostatic control device includes a thermostatic valve with notches that allow metered flow of coolant fluid to the heat exchanging circuit during opening of the thermostatic valve.
