摘要： A two-phase valve is provided, including a valve body configured for being at least partially immersible in a liquid phase of a working fluid. The valve body includes a first valve arrangement and a second valve arrangement. The first valve arrangement defines a first flow path for enabling venting vapor phase of the working fluid therethrough when the first valve arrangement is open, and the first valve arrangement is configured for selectively closing the first flow path when the liquid phase of the working fluid has a liquid level not less than a first threshold value. The second valve arrangement defines a second flow path for enabling passage of the liquid phase of the working fluid therethrough when the second valve arrangement is open, and the second valve arrangement is configured for selectively closing the second flow path when the liquid level of the liquid phase of said working fluid is not less than a second threshold value. The second threshold value is lower than the first threshold value.

摘要： A pressure relief valve (10) is provided for controlling fluid flow between a first fluid path (12a) and a second fluid path (12b). The pressure relief valve includes a housing (14), a diaphragm member (24) movably affixed within the housing and having a fluid port (18), a first biasing member (20) for urging the diaphragm member in a first direction, and a sealing member (26) movably mounted in the housing and configured for reversibly sealing the fluid port (18). When a pressure at the second fluid path (12b) exceeds a first predetermined threshold the diaphragm member (24) is pushed against the first biasing member (20), and the sealing member (26) is initially urged towards the fluid port (18) and subsequently becomes disengaged with the fluid port, allowing fluid communication between the second fluid path (12b) and the first fluid path (12a) via the fluid port. When the pressure at the second fluid path (12b) decreases below a second predetermined threshold, the sealing member (26) becomes disengaged from the diaphragm member (24), allowing fluid communication between the first fluid path and the second fluid path via the fluid port. A valve assembly including the pressure release valve (10) and an externally actuated valve (60) is also provided.
