20110155266 | Pressurized Gas Dispensing Device, Assembly Including Such a Device and a Control Device, and Container Provided with such a Dispensing Device - The invention relates to a pressurized gas dispensing device such as a tap, which includes a first end, to be placed in the opening of a pressurized gas storage tank, and a second end, including a connection interface selectively connectable to a device for controlling the filling and/or withdrawal of gas from the tank, the dispensing device including an internal gas circuit having an upstream end connecting inside the tank and a downstream end to be connected to said filling and/or withdrawal control device, the internal circuit including in series, upstream to downstream, a pressure regulator and a downstream insulation valve, the portion of the internal circuit located between the pressure regulator and the downstream insulation valve defining a so-called low-pressure chamber, the dispensing device; being characterized in that the connection interface includes at least one safety lock selectively movable between a first rest position, wherein the lock shapes the connection interface into a first configuration connectable to said combined filling and/or withdrawal control device, and a second active position, wherein the lock shapes the connection interface into a second configuration preventing connection to a combined filling and/or withdrawal control device, the safety lock being subject to the pressure in the so-called low-pressure chamber directly and/or via an intermediate transmission member such as a movable piston, the safety lock being moved to the active position thereof by the pressure in the low-pressure chamber when the pressure in the low-pressure chamber is greater than a predetermined threshold. | 06-30-2011 |
20120298222 | FLOW CONTROL VALVE - Provided is a two-stage valve including a housing fitted with an inlet port extending to an inlet chamber and configured for coupling to an upstream liquid supply line, and an outlet port extending from an outlet chamber and configured for coupling to a downstream supply line; a high flow-rate path extending between the inlet chamber and the outlet chamber fitted with a hydraulic element configured for selectively admitting liquid flow therebetween at a demand position defined by substantially high flow; and a pressure regulating unit configured for controlling a pressure regulating flow path providing direct or indirect flow communication between the inlet chamber and the outlet chamber for allowing liquid flow therebetween at a leak position defined by substantially low flow rates. | 11-29-2012 |
20130008531 | Pressure Reducing Valves with Multiple Heads and Seats - The present invention provides a pressure reducing valve. The pressure reduction valve includes a main body, an inlet, an outlet, a stem, a main seat, a pilot diaphragm, a main head, and a control spring. The pressure reduction valve includes additional auxiliary seats with corresponding auxiliary heads and displacement members/surfaces. The pressure reduction valve additional includes auxiliary seats with corresponding auxiliary heads and displacement members/surfaces enables stage wise opening of the secondary seats and the main seat. This enables to meet highly varying media flow demands using single pressure reduction valve, having less hunting effect and eliminating use of multiple pressure reduction valves. | 01-10-2013 |
20130118610 | HIGH-PRESSURE REGULATOR FOR COMPRESSED-AIR WEAPONS - A high pressure regulator for compressed gas weapons, and in particular for paintball markers, is situated inside a cylindrical regulator housing which is connected to a source of compressed gas. The cylindrical regulator housing comprises an inlet channel which is connected to a supply of high-pressure gas. A first regulator (H) comprises a first piston movably disposed within the regulator housing for regulating pressure in a first expansion chamber. A second regulator (D) comprises a second piston movably disposed within the regulator housing for regulating pressure in a second expansion chamber. The first piston and the second piston are arranged coaxially within the regulator housing. The high pressure regulator is suitable to be mounted in the foregrip of a paintball marker and reduce an inlet pressure of about 850 psi to a first pressure of about 250 psi and a second pressure of about 100 psi. | 05-16-2013 |
20140102560 | Multi-Stage Pressure Regulator and Method for Fluid Pressure Regulation - A multi-stage fluid pressure regulator, including a first stage valve arranged to open and close a fluid flow path to control flow of fluid through the valve, a first stage piston arranged for movement to open and close the first stage valve, the piston having an inner side and an outer side, a gas delivery conduit having a proximal end attached to the first stage piston and a distal end extending away from the first stage piston, the gas delivery conduit having a passage in fluid communication with the inner side of the first stage piston, and a second stage valve in fluid communication with the gas delivery conduit, the second stage valve including a second valve chamber into which the distal end of the gas delivery conduit is positioned. | 04-17-2014 |
20160116920 | DYNAMIC PRESSURE REGISTRATION DEVICE FOR INTERNALLY REGISTERED ACTUATORS AND OVERPRESSURE PROTECTION DEVICES - A fluid regulating device includes a regulator valve having an inlet, an outlet, and a valve port disposed between the inlet and the outlet. An actuator is coupled to the regulator valve and includes a valve disc that displaces between a closed position and an open position. The device also includes an overpressure protection device adapted to stop flow from the inlet to the outlet when pressure in a control cavity reaches a predetermined level. The overpressure protection device includes a sensing tube having a first end in fluid communication with the control cavity and a second end in fluid communication with the outlet. The sensing tube has a first portion extending parallel to the flow axis. One or more apertures are disposed in the sensing tube adjacent to the second end, and each of the apertures has a centerline that is perpendicular to the flow axis. | 04-28-2016 |
20160187892 | MULTI-STAGE BACK PRESSURE REGULATORS AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS - Multi-stage back pressure regulators are disclosed herein. In one embodiment, a multi-stage back pressure regulator includes a first stage and a second stage downstream from the first stage. The first stage includes a gas-charged regulator device arranged to receive a fluid at an inlet, and the second stage includes a spring-loaded regulator device having an outlet in fluid communication with the inlet. The gas-charged regulator and the spring-loaded regulator are configured to control inlet pressure to the back pressure regulator and maximum differential pressures across the first and second stages. | 06-30-2016 |
