摘要： A fluid regulating device includes a regulator valve having a valve body defining an inlet and an outlet and a valve port disposed between the inlet and the outlet. A housing assembly is disposed adjacent the valve port, and the housing assembly includes a first aperture adapted to receive a valve disc. A balancing diaphragm is secured to a portion of the valve disc and a portion of the housing assembly, and a portion of a balancing cavity is defined by a top surface of the balancing diaphragm and an interior surface of the housing assembly. A sensing passage extends from the inlet of the regulator valve to the balancing cavity such that the inlet of the regulator valve is in fluid communication with the balancing cavity.

摘要： An example loading regulator having an internal relief valve apparatus includes a body having a loading diaphragm disposed between a first casing and a second casing. The first casing and a first side of the loading diaphragm define a first chamber and the second casing and a second side of the loading diaphragm define a second chamber. A relief valve assembly is coupled to the loading diaphragm. The relief valve assembly includes a relief valve seat having an aperture that forms a passageway to fluidly couple the first chamber and the second chamber and a relief valve plug movably coupled to the relief valve seat. The relief valve plug is to move away from the relief valve seat to a bleed position to allow the flow of fluid between the first chamber and the second chamber in response to an outlet pressure substantially greater than a pressure at which the loading regulator enters a lock-up condition.

摘要： A pressure regulating valve particularly useful in diesel internal combustion engine with a closed crankcase is provided. The valve includes a body (10) coupled to a bonnet (62) with an internal moveable piston (20). The moveable piston (20) maintains a substantially constant pressure in the crankcase by adjusting a fluid flow in response to changes in pressure. The piston (20) also includes an integral relief valve (44) to prevent overpressure in the event of a crankcase pressure in excess of the designed limits of the pressure regulating valve.

摘要： Es wird ein Druckregelventil mit Sekundärentlüftungsmaßnahmen vorgeschlagen. Es enthält ein Steuerglied (14) zur Steuerung der Fluidverbindung zwischen einem Primärkanal (6) und einem Sekundärkanal (7). Die Stellung des Steuergliedes (14) ist durch ein mit einer einstellbaren Vorgabekraft beaufschlagbares bewegliches Stellglied (26) beeinflußbar, das eine ebenfalls von dem Steuerglied (14) gesteuerte und zur Entlüftung des Sekundärkanals (7) dienende Entlüftungsöffnung (48) aufweist. Die Entlüftungsöffnung (48) ist so am Stellglied (26) angeordnet, daß sie sich außerhalb der Vergleichskammer (27) und dabei entweder unmittelbar im Sekundärkanal (7) oder in einem mit dem Sekundärkanal (7) in Verbindung stehenden Bereich befindet.

摘要： A fail-safe, precision current-to-pressure converter for providing a regulated pneumatic output pressure proportional to an electrical control current (21) includes a main valve member (4) for regulating the pneumatic output pressure at outlet (3), operation of the valve member (4) being controlled by the pressure of control fluid contained in a chamber (11). The control fluid pressure is controlled by admitting control fluid into the chamber (1) via a continuously pulsed, electromagnetically actuated on/off reed valve (16) and simultaneously allowing control fluid continuously to exhaust to atmosphere via a fixed bleed orifice (17), the rate of admittance of control fluid into the chamber (11) relative to the exhaust rate from the orifice (17) being variable so that the desired, substantially constant output pressure, as dictated by the electrical current input (21) and as measured by a transducer (15) that produces a feed-back signal, will be attained. In the event that the input current (21) fails, the valve (16) remains closed and continued exhaust of control fluid from the chamber (11) causes the control fluid pressure, and therefore the output pressure at (3), to fall to atmospheric pressure, ie the converter fails to "zero" in such event.
Because of its relatively simple design, a converter of the invention is somewhat more rugged and less expensive to manufacture than prior I/P converters.

摘要： A pneumatic regulator in the form of an electro-pneumatic device (an I/P regulator) in which the pressure of pneumatic medium is controlled in response to an electrical signal in which the pneumatic pressure regulator incorporates a control volume whose pressure is used to regulate the main pneumatic pressure and the pressure in the control volume being under the control of pneumatic valves, the valves being opened and closed by electrical signals provided by an electrical circuit, which circuit incorporates electrical storage so as to permit the electrical circuitry to operate the valve on currents in the range 4-20 mA so that the electro-pneumatic regulator can be operated directly by electronic control systems without the need of supplementary electrical feeds.
