A vent limiting device adapted to be operably coupled to an exhaust vent of a fluid regulator. The vent limiting device includes a housing, a poppet disposed in the housing, and a retaining element arranged to retain the poppet in the housing. The housing has a fluid passageway extending between a fluid inlet and a fluid outlet. The poppet is movably disposed in the housing, responsive to pressure at the fluid outlet, to control fluid flow through the fluid passageway. The housing includes one or more retaining features that engage the retaining element to retain the retaining element in the housing.

The invention relates to a valve for controlling a fluid flow, comprising at least one valve housing having at least one inlet and one outlet side, and a valve insert for regulating the fluid flow between the inlet side and the outlet side, which valve is arranged within the valve housing. The valve insert comprises at least one first element, designed as a hollow body, and a second element, wherein the second element is arranged within the first hollow-body-shaped element. Furthermore, the valve insert is arranged within the valve housing in such a way that the first element is axially fixed in the valve housing, and the second element is arranged so as to be rotationally fixed in the valve housing. The first element has at least one opening along the circumference of the first element for passing the fluid flow through and is designed to be rotatable relative to the second element; the second element is designed to be axially movable relative to the first element.

A pressure independent control valve contains a valve body with an inlet, an outlet and a flow channel coupling the inlet to the outlet. A hollow piston is arranged in a seat in the valve body, such that the hollow piston is configured to move. The hollow piston has an enclosure, such that the pressure independent control valve maintains different fluid pressures in the flow channel and inside the hollow piston. The pressure independent control valve contains a chamber and a biasing member to urge the hollow piston towards the chamber. The chamber is in fluid communication with the inlet and with the inside of the hollow piston, such that the valve applies substantially the same pressure inside the annular channel, at the inlet and inside the hollow piston.

A valve includes an inlet unit including an inlet hole into which a fluid is introduced, a pressure adjusting unit which adjusts a pressure of the fluid introduced through the inlet unit, and a discharging unit having an opening and closing member which selectively discharges the fluid which had its pressure adjusted, and a water outlet hole which discharges the fluid passing through the opening and closing member to the outside, wherein a cross-sectional area of the inlet hole is greater than a cross-sectional area of the water outlet hole and a flow direction of a fluid from the pressure adjusting unit to the opening and closing member and a flow direction of a fluid from the opening and closing member to the water outlet hole are perpendicular to each other.

An infusion arrangement for administering a medical fluid includes a medical elastomer pump that produces a delivery pressure dependent on expansion and thus is variable over an infusion duration, a fluid conduit path provided for discharging the medical fluid from the elastomer pump, and a fluid control device arranged in the fluid conduit path and designed to influence a volumetric flow of the medical fluid delivered through the fluid conduit path by the elastomer pump. The fluid control device has a hydraulic flow-regulating valve designed to regulate the volumetric flow to a setpoint value and is provided with a throttle action that is automatically variable at least in accordance with the delivery pressure. The infusion arrangement can be used in infusion therapy.

A flow and pressure stabilization device includes a housing; a first fluid chamber; a gas chamber; a deformable bladder that separates the first fluid chamber from the gas chamber, the deformable bladder comprising a longitudinally protruding portion shaped such that, when a pressure in the gas chamber is greater than a pressure in the first fluid chamber, the longitudinally protruding portion extends toward the first fluid chamber; and a valve in fluid communication with a fluid outlet, the valve including: a second fluid chamber in fluid communication with the first fluid chamber; a fluid port in fluid communication with the fluid outlet; and a deformable diaphragm positioned adjacent to and biased toward the fluid port.

A cartridge flow rate adjusting assembly for a hydraulic valve, may include a cartridge body, a stem that is slidingly disposed in the cartridge body, and a shutter to be slidingly placed against a passage opening. The cartridge flow rate adjusting assembly may further include a sleeve rotatively disposed inside the valve that may include at least one first opening to enable adjustment of a maximum flow rate of the valve within a first range of values, and according to a first scale at least one second opening made in the wall to enable adjustment of the maximum flow rate of the valve within a second range of values according to a second scale. A hydraulic control valve is also provided that comprises a cartridge flow rate adjusting assembly.

A method of obtaining the output flow rate of the flow rate controller according to an aspect is provided. The method including a first step of outputting gas whose flow rate is adjusted according to a designated set flow rate from the flow rate controller, in a state where the diaphragm mechanism is opened; a second step of adjusting the diaphragm mechanism so that the pressure in the second pipe is the target pressure value, in a state where the output of gas from the flow rate controller is continued in the first step; and a third step of obtaining the output flow rate of the flow rate controller by using a pressure value and a temperature value in the tank, after the pressure in the second pipe is set to the target pressure value in the second step.

A charging apparatus for inductive charging. The charging apparatus comprises one or more charging coils configured to transfer power to a mobile apparatus and at least one flexible diaphragm configured so that movement of the flexible diaphragm directs air flow towards the mobile apparatus. At least one of, the one or more charging coils or actuating circuitry for actuating the one or more charging coils are mounted on the flexible diaphragm
