摘要： A mechanical valve for adjusting coolant flow which may be opened and closed based on the pressure of a coolant and a fuel cell cooling system using the same are provided. The valve has a mechanical valve structure to be opened and closed by the pressure of a coolant introduced into a coolant inlet and thus blocks and permits the coolant circulated to an ion filter line during operation of a fuel cell stack at the maximum output. The valve performs a coolant flow blocking function executed by a conventional electronic valve and thus a fuel cell cooling system has a simplified structure using the valve.

摘要： Multidirectional vent limiting devices for use with fluid regulators are described. In some examples, a vent limiting device includes a housing having an interior surface, a fluid inlet, a fluid outlet, and a first fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. The interior surface includes a first sealing surface that defines a portion of the first fluid passageway. In some examples, the vent limiting device further includes a stem and a poppet. In some examples, the stem is rigidly coupled to the interior surface of the housing. In some examples, the poppet includes a second sealing surface that defines a portion of the first fluid passageway, and a radial bore that defines a second fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. In some examples, the poppet is slidable along the stem between an open position and a closed position. In some examples, the second sealing surface contacts the first sealing surface when the poppet is in the closed position to close off the first fluid passageway.

摘要： A throttling device is equipped with a valve seat in which a valve port for connecting a primary chamber and a secondary chamber is formed, a needle valve, a needle section which is inserted into the valve port, a guide section for guiding a slide shaft of the needle valve, and a coil spring for biasing the needle valve in a valve-closing direction. The guide section and the coil spring are positioned on the primary chamber side. The position of the needle valve in the valve-closing direction is restricted by a stopper section in a manner such that the minimum gap between the needle valve and the valve port is maintained. Furthermore, the needle valve is not seated on the valve seat.

摘要： Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.

摘要： There is provided a pressure reducing valve in which phenomena of vibration occurring with respect to a pressure reducing member and/or a pressure receiving piston are reliably dampened. When a pressure receiving piston (19) is advanced rightward to increase the volume of a fluid chamber (28) defined by the pressure receiving piston (19) and a piston hole (18), the pressure in the fluid chamber (28) drops to close a check valve (34), and the pressurized fluid in an outlet chamber (10) flows into the fluid chamber (28) through a throttle portion (31). When the pressure receiving piston (19) is retracted leftward to reduce the volume of the fluid chamber (28), the pressure in the fluid chamber (28) rises to open the check valve (34), and the pressurized fluid in the fluid chamber (28) flows out to the outlet chamber (10).

摘要： A valve device comprises a body, a rotating valve set and a safety valve set. The body comprises an inner space, a first opening and a second opening. When the rotating valve set is located in a water-providing position, the inner space, the first opening and the second opening are communicable. When water pressure is higher than a safe pressure, the safety valve set and the rotating valve set can block the first opening and the second opening that safe pressure is maintained at the second opening. When water pressure becomes normal, the safety valve set is moved to its original position. Therefore, it has a piston-typed safety valve set is highly reliable. It has a coaxial structure to reduce its volume. It has an engaging and hooking structure for precise and easy assembly. It has an opening and/or closing function for its valve body with wide range of applications.

摘要： A connecting structure includes housing, a first fixing member, a second fixing member, a sealing member, and an elastic member. A stepped hole is defined on the housing, and includes a first vent, a second vent, and a third vent communicating with each other. A diameter of the second vent is gradually decreased from the first vent toward the third vent, thereby forming a resisting surface on a periphery of the second vent. The first fixing member and the second fixing member are mounted on opposite ends of the housing. The sealing member includes a sealing portion with an exhaust opening. The sealing member is received in the first and second vents, and resisting against the first fixing member. The exhaust opening communicates with the first and second vents. The elastic member is received in the third vent, and resisting between the second fixing member and the sealing member.

摘要： A self-regulating pressure throttle configured for use in a fluid conduit includes a throttle body having a series of segments. The throttle body includes an inlet end and an outlet end. The throttle body includes a cone portion and a rim portion. The cone portion tapers away from the rim portion from a first end to a second end. The second end includes a nozzle orifice. The series of segments can be formed on the cone portion. The series of segments are configured to move between (i) a first position wherein the nozzle orifice has a first diameter and (ii) a second position wherein the nozzle orifice has a second diameter. The second diameter is smaller than the first diameter. The series of segments can be configured to move from the first position to the second position upon an increased pressure flow of fluid at the inlet end.
