摘要： A plug for regulating a flow of gas in a system is disclosed. The plug includes a housing disposed on a temperature boundary in a system. The housing defines a passage for flowing gas therethrough. The plug further includes at least one pressure-actuated valve disposed in the passage and movable between an open position and a closed position. The at least one pressure-actuated valve moves from the open position to the closed position as the pressure of the gas increases and moves from the closed position to the open position as the pressure of the gas decreases.

摘要： A valve for controlling cryogen egress from a cryogen vessel has a housing having a low pressure side and a high pressure side with a fluid path defined between. A valve element is interposed between the low pressure side and the high pressure side of the housing. A mechanism is provided for holding the valve element against a valve seat. The mechanism has a cam shaft that is rotatable to displace the valve element from its seat to open the fluid path.

摘要： A pressure relief valve for releasing pressure from a system, which pressure relief valve typically includes a valve housing provided on a pressure relief conduit which receives pressure from the system. A valve opening establishes communication between the valve housing and the pressure relief conduit, and a substantially arcuate valve body is pivotally mounted in the valve housing for sealingly and slidably engaging the valve opening. Accordingly, the valve body is capable of pivoting between a first position to close the pressure relief conduit and a second position to open the pressure relief conduit as the valve body slidably traverses the valve opening. A bias mechanism biases the valve body in the closed position in such a manner that the valve body pivots from the closed position to the open position against the bias mechanism and opens the pressure relief conduit, responsive to a threshold pressure of the pressurized fluid impinging against the valve body in the pressure relief conduit.

摘要： An audible pressure relief valve for a medical humidifier used in inhalation therapy. This valve relieves pressure from the humidifier when there is a kink or obstruction in a humidified oxygen tube leading to a patient''s mask, nasal cannula or tent. The valve has a rubber disc that is dimensionally tuned to vibrate against a valve seat and emit an audible sound over a wide range of oxygen flow rates. This valve audibly vibrates at gas flow rates of 3 to 15 liters per minute and pressures of 1 to 5 psi above atmospheric pressure.

摘要： A VALVING DEVICE IN PARTICULAR FOR ELECTROCHEMICAL GENERATORS OF SEMI-SEALED TYPE CAPABLE OF PROVING EXIT CINMUNICATION BETWEEN THE ENCLOSURE OF THE GENERATOR AND THE EXTERIOR ENVIRONMENT, THE VALVING DEVICE BEING OF A TYPE COMPRISING A HOLLOW PART HAVING A CAVITY IN COMMUNICATION WITH SAID ENCLOSURE AND THE EXTERIOR VIA ONE OR MORE EXIT ORIFICES OR PASSAGES WHICH PLACE THE ENCLOSURE IN COMMUNICATION WITH THE EXTERIOR ENVIRONMENT AND INCLUDING AN OBTURATING ELASTIC BODY LODGED IN SHCH CAVITY AND CAPABLE OF VOLUMETRIC CHANGE FOR FREEING OR CLEARING SAID EXIT ORIFICES OR PASSAGES UNDER GIVEN DIFFERENTIAL PRESSURES APPEARING BETWEEN SAID ENCLOSURE AND SAID EXTERIOR ENVIROMENT AND SEALING OR OBTURATING SAID ORFICES OR PASSAGES WHEN SAID PRESSURE DIFFERENTIAL CONDITIONS ARE NOT PRESENT. THE OBTURATING BODY LODGED IN THE CAVITY IS COMPRESSIBLE THE ELASTIC AND IS VOLUME IS VARIABLE AND DECREASES AS PRESSURE UPON IT INCREASES, BEING CONSITUTED PRIMARILY OF AN ELASTIC POROUS OF ALVEOLATE BODY WHOSE PORES OR CELLS ARE SEALED OFF AND CONTAIN GAS SUCH AS IMPRISONED AIR THAT IS COMPRESSIBLE. THE VARIATION IN ELASTIC VOLUME OF THE BODY IS OBTAINED THANKS TO THE COMPRESSIBILITY OF THE IMPRISONED GAS IN ONE OR MORE OF THE PORES OR CELLS THAT ARE BOUNDED BY ELASTIC PARTITIONING WALLS.
