| 20140299800 | Gas Bottle Valve Provided With A Flywheel Controlling A Residual-Pressure Valve And A Stop Valve - The invention relates to a valve for a gas cylinder pressure. It includes a body with a gas inlet, a gas outlet and a gas passage connecting the net to the outlet. The valve comprises a residual pressure holding disposed at the gas passage. It also comprises a valve for closing the gas passage downstream of the residual pressure holding. A flywheel control valve acts on the valve and on the holding device via a residual pressure control rod and, respectively. The steering wheel includes sliding tracks for the control rods. It comprises a first position of the bottle filling device where the residual pressure holding is turned off and the valve is open, a second dosed position of the bottle where the holding device is active residual pressure valve and is closed, and a third operative position where the holding device is active residual pressure and the valve is opened. | 10-09-2014 |

| 20090078895 | Flow Control Valve - A flow control valve comprising a housing, in turn comprising a substance inlet opening and a substance outlet opening and a substance channel extending between the substance inlet and outlet openings. The valve further comprises: a piston carried by the housing and movable relative thereto; a first biasing member biasing the piston towards a first piston postion in which the piston seals the substance channel; a guide channel carried by the housing; and a valve actuator movable along and whithin the guide channel between first and second actuator positions. Furthermore, the control valve comprises a second biasing member capable of biasing the piston against the bias of the first biasing member towards a second piston position in which the piston clears the substance channel, whereby the bias of the second biasing member overtakes the bias of the first biasing member on the piston when the valve actuator is in the second actuator position, without however overtaking the bias of the first biasing member when the valve actuator is in the first actuator position. When the elongated guide channel is sufficiently tilted, the valve actuator will move from the first actuator position towards the second actuator position resulting in the bias of the second biasing member overtaking the bias of the first biasing member on the piston and the piston thus being moved towards the second piston position. The movement of the piston is delayed according to the time it takes for the valve actuator to move from the first actuator position to the second actuator position. | 03-26-2009 |

| 20090039299 | DUAL BY-PASS FOR DIAPHRAGM TYPE FLUSHOMETERS - A flush valve diaphragm is provided. The diaphragm includes at least two by-passes orifices. Each by-pass orifice in the diaphragm has a by-pass associated therewith. Each by-pass having a passage therethrough, allows communication with the control chamber above the diaphragm with an inlet chamber below the diaphragm. The diaphragm also integrates the function of locating and providing sealing means to the flush valve system's aux valve mechanism. | 02-12-2009 |
| 20110248197 | DUAL BY-PASS FOR DIAPHRAGM TYPE FLUSHOMETERS - A flush valve diaphragm is provided. The diaphragm includes at least two by-passes orifices. Each by-pass orifice in the diaphragm has a by-pass associated therewith. Each by-pass having a passage therethrough, allows communication with the control chamber above the diaphragm with an inlet chamber below the diaphragm. The diaphragm also integrates the function of locating and providing sealing means to the flush valve system's aux valve mechanism. | 10-13-2011 |
| 20160186419 | Flush Valve Diaphragm - A diaphragm for use in a diaphragm-type flush valve includes a flexible diaphragm body having a first side and a second side and an outer periphery, a center passageway defined in the diaphragm body, a bypass orifice defined in the diaphragm body, and a sealing ring attached to the outer periphery of the flexible diaphragm body. The sealing ring defines an outer circumferential surface of the diaphragm. The outer circumferential surface of the sealing ring defines a recessed area. The recessed area is configured to be positioned in a keyed relationship with a flush valve body. | 06-30-2016 |
| 251043000 | Main valve biased open by line pressure | 5 |
| 20140332702 | HIGH PERFORMANCE PULSE VALVE - A pulse valve arrangement includes a valve housing on which is fixed a control valve The valve housing includes a circular cylindrical portion with a valve member movably arranged therein. The valve chamber has an inlet adapted to be connected to a pressure medium source for allowing pressure medium to flow into the valve chamber and an outlet through which pressure medium flows out of the valve chamber. The control valve may be closed in which the outlet of the valve chamber is moved to a closing position blocking the flow of pressure medium, or may be opened in which the outlet of the valve chamber is moved to an opening position allowing a pulse of pressure medium therethrough. The valve member within the valve housing is freely displaceable within the circular cylindrical portion of the valve housing based on the pressure within the valve chamber as controlled by the control valve. | 11-13-2014 |

| 20130306887 | VALVE ARRANGEMENT - The invention concerns a valve arrangement ( | 11-21-2013 |
| 20140117264 | VALVE - A valve, in particular a vacuum valve, in which, in order to close a passage opening, in particular of the valve, at least one closure member can be moved by a valve drive, starting from a maximum open position, in which the closure member opens the passage opening at least partially, first on a first partial path into an intermediate position, and the closure member can be moved, starting from the intermediate position, on at least one second partial path which is angled away from the first partial path into a closed position, in which the closure member closes the passage opening, the valve drive having at least two cylinder spaces which are loadable in each case with a pressure medium, at least one piston being mounted displaceably in each of the cylinder spaces, and the pistons being supported on one another by way of at least one prestressing element. | 05-01-2014 |

| 20110068284 | Control Valve - The control valve according to the invention is for use in liquid carrying systems. It comprises a valve housing ( | 03-24-2011 |
| 20150345654 | FORCE ACTUATED CONTROL VALVE - The disclosed embodiments include a force actuated modulating control valve such as a direct acting solenoid valve or pilot actuated bellows valve with a knife edge seat so that the metering location on the seat is at the very outer diameter. In one embodiment, a portion of the valve seat outside of the metering edge is removed to substantially the outside diameter to reduce contact with high velocity fluid flow. In certain embodiments, a flow shield may be positioned just outside of the metering edge of the seat to prevent the high velocity fluid from circulating toward parts of the spool assembly. In some embodiments, the flow shield may be fixed to the body of the instrument so all fluid forces are transmitted to the body. Embodiments of the force actuated modulating control valve may be employed in a mass flow controller for controlling fluid flow. | 12-03-2015 |
