The invention is a gas vent valve (10) for a gas pressure regulator (1), comprising: a tubular body (11) developed between two opposite openings (11a, 11b); a shutter body (12) biased towards a position in which a first opening (11a) of the tubular body (11) is closed and movable from the closed position towards an open position for opening the first opening (11a) due to the effect of a pressure acting from the outside of the tubular body (11) through the first opening (11a); constraining means (13) configured so as to prevent the movement of the shutter body (12) from the closed position towards the open position when the ambient temperature exceeds a predefined value.

A wheel mounted control assembly receives therethrough the tire valve stem from an air maintenance tire. A control assembly regulator controls a flow of air to and from a tire-mounted air pumping tube. The control assembly includes a bi-directional air distribution flow control system having multiple parallel air pathways, each air pathway coupled to a respective conduit connected to an air pumping tube mounted within a tire sidewall. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.

A valve arrangement including: a valve inlet, a valve outlet arranged downstream of the valve inlet, a first chamber arranged directly downstream of the inlet, and a second chamber arranged between the first chamber and the valve outlet. The valve arrangement further includes a measuring nipple comprising a measuring channel for receiving a measuring device, and a closing arrangement having open positions and a closed position, wherein the closing arrangement in its closed position is configured to prevent fluid communication between the first chamber and the second chamber via the closing arrangement, and wherein the closing arrangement in its open positions is configured to allow for fluid communication between the first chamber and the second chamber via the closing arrangement.

Valve for fluid and gaseous media, more particularly for regulating the pressure in pipelines, containing a housing of at least one upper and lower part, a pressure adjustment unit, wherein the pressure adjustment unit comprises a spindle, a spring plate, a spring holder and at least one spring, a cartridge, wherein the cartridge forms a function unit by means of which the function of the valve is defined, wherein the cartridge preferably contains an interior housing, a fastening means, a poppet and a diaphragm, wherein the diaphragm serves for dividing the housing into a medium-free and a medium-flowing area, wherein the cartridge is pre-fitted as a function unit and is disposed replaceably as a complete unit in the housing.

In some examples, a pressure reducing valve includes a valve body defining a defining a flow path and a restricting element within the flow path. A sensing element is configured to modify a position of the restricting element in the flow path. A pressure chamber is configured to transmit a force to the sensing element based on the pressure of a fluid within the pressure chamber. An energy accumulator is in fluid communication with the pressure chamber. The pressure reducing valve includes control circuitry configured to enable a fluid to flow into or discharge from the pressure chamber to alter the pressure in the pressure chamber.

A pressure reducing valve includes a valve housing, plunger, pressure sensing cavity, and biasing member. The valve housing includes a valve inlet and valve outlet in selective fluid communication with each other. The plunger is in the valve housing and movable between a closed position and open position. The plunger is positioned downstream from the valve inlet and upstream from the valve outlet. The plunger includes a venturi and a channel. The venturi is within the plunger and has a venturi inlet and venturi outlet. The channel is within the plunger and is in fluid communication with the venturi. The pressure sensing cavity is in fluid communication with the channel. The biasing member exerts a biasing force on the plunger toward the open position. The channel is in fluid communication with the pressure sensing cavity to provide a fluid pressure that is lower than the outlet pressure during flow.

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.

The invention relates to a valve device (1) having a pressure regulator (3) for a flowing gas and a housing (4). The pressure regulator (3) includes a diaphragm (31), a spring (34), a control actuator (32), and a control seat (33). The control actuator (32) includes a plate-like portion (32′) and a rod-like portion (32″) adjacent to one side of the plate-like portion (32′), the control seat (31) encompassing the rod-like portion (32″) of the control actuator (32). The diaphragm (31) and the control actuator (32) are mechanically coupled to each other such that an axial movement of the control actuator (32) moves the diaphragm (31). In addition, the spring (34) and the control actuator (32) are mechanically coupled to each other. The control seat (33) limits a movement of the control actuator (32). In one state, the control seat (33) and the control actuator (32) prevent the gas from flowing. The control seat (33) is configured as a ring arranged in a recess (40) of the housing (4).

A back pressure regulator (“BPR”) includes a pressure housing that at least partially defines a flow chamber that the liquid flows through and the BPR has an adjustable restriction that varies with the flow rate to maintain an upstream liquid pressure. The pressure housing is contoured to distribute the liquid flow to provide radial flow into the adjustable restriction from circumferentially about the adjustable restriction. The pressure housing includes ramped and curved side passages that guide the flow and ridges that divide the flow and prevent internal collisions between the flow. A flow deflector extends into the chamber outlet to prevent the radial flows through the annular restriction from colliding. The flow deflector redirects the flows to smoothly recombine in the chamber outlet.

A pressure regulating valve assembly includes: a valve having an upstream side receiving an input flow and a downstream side providing an output flow, an actuator for opening and closing the valve, including partially opening the valve, and a regulator controlling the actuator to open, close or partially open the valve. The regulator includes a sense pressure port, wherein pressure at the port is maintained constant by the regulator. A chamber has a first entry orifice, a second entry orifice and an exit orifice. The first entry orifice is connected to the upstream side, the second entry orifice is connected to the downstream side, and the exit orifice is connected to the port. The exit orifice provides that the pressure at the exit orifice lies between the pressure at the first entry orifice and the pressure at the second entry orifice.
