    摘要： A system including: a temperature responsive polymer configured to expand to a cross-sectional area of a fluid channel when a temperature of the fluid in the fluid channel is greater than or equal to a temperature threshold Tth, and to retract to less than the cross-sectional area when the temperature of the fluid in the fluid channel is less than Tth, an expandable material layer surrounding the temperature responsive polymer and configured to expand and retract with the expansion and retraction of the temperature responsive polymer, and a sieve housing encasing the expandable material and being configured to be disposed in the fluid channel, wherein when the temperature of the fluid in the fluid channel is greater than or equal to Tth, the temperature responsive polymer expands to the cross-sectional area such that the expandable material layer prevents the fluid in the fluid channel from passing through the sieve housing.

    摘要： A tunable oscillating heat pipe system that includes an oscillating closed loop heat pipe configured for movement of a fluid in an internal passage in the closed loop to transfer heat from a first portion of the closed loop to a second portion. The heat pipe system further includes a valve arranged in a section of the internal passage movable between an open position and a closed position. In the open position, the valve is arranged to permit movement of the fluid in the internal passage and in the closed position, the valve is arranged in the internal passage to limit movement of the fluid in a part of the internal passage. Movement of the valve between the open position and the closed position can be a function of at least one of temperature at the first portion, temperature at the second portion, or temperature at the valve.

    摘要： Provided is a thermos-valve connecting body with which attachment work is simplified by integrating a plurality of thermos-valves. The thermos-valve includes: a housing; a thermos-element that includes a temperature-sensing unit that senses the temperature of a coolant, that opens and closes one flow path in accordance with the temperature of the coolant, and that is housed inside the housing; and a connecting part formed on the housing and attached to another thermos-valve. The thermos-valve connecting body enables one thermos-valve to be attached to a connecting part of the other thermos-valve by the connecting part formed on the housing, and the one thermos-valve and the other thermos-valve to be formed integrally.

    摘要： A method for assembling a piezo valve can include providing a cable having first and second contacts, forming a pocket between the first and second contacts, inserting at least a portion of a piezo element into the pocket, electrically coupling the first contact to a first layer of the piezo element, and electrically coupling the second contact to a second layer of the piezo element. Forming the pocket between the first and second contacts can include moving the second contact from a first position, in which the first and second contacts can be coplanar, to a second position, in which the first and second contacts can be disposed in different planes.

    摘要： A valve for a pneumatic system, has: a first enclosure defining a first chamber and a first connection port; a second enclosure defining a second chamber and a second connection port; a first shell subjected to a first pressure differential and movable from a default position to a reversed position via snap-through buckling upon the first pressure differential reaching a threshold; and a second shell having a shape different than a shape of the first shell, the second shell resiliently movable from an initial position to a deformed position when subjected to a second pressure differential, wherein a first flow rate of a fluid via the first connection port induces deformation of the second shell followed by a snapping of the first shell thereby generating a second flow rate greater than the first flow rate.
