|20130139910||PRESSURE REDUCER FOR A DEVICE FOR ENRICHING A LIQUID WITH CARBON DIOXIDE - A pressure reducer includes a housing with an axially displaceable biased control body in order to close a connection between an inlet and an expansion chamber, where the housing is equipped with an axially displaceable biased actuating piston in order to displace the control body against the spring load of the control body as a function of the pressure in the expansion chamber and to open the connection, the housing being made of plastic, and the pressure reducer includes a separately made insert, where the insert is fixed between the inlet and the expansion chamber in the plastic housing and said insert has a guide bore, which is connected to the inlet and supports the control body, and a connecting bore, which adjoins the guide bore and which opens into the expansion chamber, where the insert forms an annular shoulder surface between the connecting bore and the guide bore, said shoulder surface interacting as a seating surface with the seal on the control body.||06-06-2013|
|20120152571||A HIGH PRESSURE GAS DISCHARGE VALVE FOR A FIRE-EXTINGUISHING OR EXPLOSION-PREVENTING SYSTEM - A high pressure gas discharge valve for a fire-extinguishing or explosion-preventing system including: a valve body with a gas inlet channel and a gas outlet channel; a valve seat arranged between the channels; and a triggering chamber; a closing piston which is slidably movable within the valve body and has a first end portion forming a pressure surface in the triggering chamber, a second end portion forming a sealing surface, with which it can be sealingly pressed against the valve seat, and a pressure compensation channel via which the triggering chamber communicates with the inlet channel when the closing piston rests on the valve seat; a triggering port in communication with the triggering chamber, for connecting thereto a low pressure triggering device that is capable of generating a pressure drop in the triggering chamber; and a pressure-reducing valve for reducing a pressure of high pressure gas to a reduced pressure suitable for the low pressure triggering device.||06-21-2012|
|20120125449||EXPANSION VALVE WITH A PLUG AND A FLOW SELECTOR - The invention relates to a valve device including a built-in expansion valve and a flow selector. The valve function is provided by a blocker mounted so as to be inverted. The expansion valve is arranged laterally and communicates with a high-pressure chamber immediately downstream from the blocker and with a low-pressure chamber via a side passage. A device for mechanically controlling the blocker is provided in a chamber sealingly separated from the high-pressure chamber and from the low-pressure chamber. A flow selector in the form of a disc with a calibrated opening is provided in the low-pressure chamber, the disc engaging with a passage directly linked to the outlet of the device. The mechanical control device engages with a control pin of the disc.||05-24-2012|

|20120038068||DEVICE FOR THE ENRICHMENT OF A LIQUID STREAM WITH A GAS - The invention relates to a device for the enrichment of a liquid stream with a gas, comprising a flow mixer (||02-16-2012|
|20110140014||HIGH PRESSURE DIAPHRAGM VALVE WITH EXCHANGEABLE SEAT ASSEMBLY - A high pressure diaphragm gas valve comprises a removable seat assembly (||06-16-2011|
|20100116515||FIRE EXTINGUISHER WITH A CONTAINER HOLDING A FIRE EXTINGUISHING SUBSTANCE AND CORRESPONDING COMPRESSED-GAS CYLINDER - A fire extinguisher (||05-13-2010|
|20100001222||VALVE, NAMELY FOR BOTTLES FOR ULTRA-HIGH PURITY GAS - A valve for pressurized or liquefied gas comprises a valve body (||01-07-2010|
|20090165867||GAS TANK CONTAINING A COMPRESSED COMBUSTIBLE GAS - A gas tank containing a compressed combustible gas is equipped with a safety relief system providing an emergency discharge of the compressed combustible gas through a relief line. The safety relief system includes a pressurized triggering hose that extends through a selected risk area around the tank, where a rupture of the triggering hose, due to a temperature increase or mechanical damage, results in a pressure drop in the safety relief system that triggers an emergency discharge of the pressurized combustible gas from said gas tank.||07-02-2009|
|20090121168||VALVE - Valve for pressurized or liquefied gas cylinder comprising a valve body (||05-14-2009|
|20090085350||SEALED FLANGE JOINT FOR HIGH PRESSURE AND HIGH PURITY GAS CHANNELS - A sealed flange joint for high pressure and/or high purity fluid channels comprises includes a first flange with a first fluid channel and a cylindrical front cavity. The front cavity is axially delimited by a ground surface and radially by a peripheral surface. The first fluid channel passes axially through the first flange to open into the ground surface. A polymer seal ring has a radial outer surface and a radial inner surface, and is fitted into the cylindrical front cavity so that its radial outer surface engages the peripheral surface of the front cavity. A second flange is removably fixed onto the first flange, and has a second fluid channel in axial continuation of the first fluid channel. The second flange has an axially protruding cylindrical front nipple with a conical head, the second fluid channel axially opening into an end surface of the conical head. The conical head engages the radial inner surface of the seal ring to radially press the latter with its radial outer surface against the peripheral surface of the front cavity.||04-02-2009|
