144 PRESSURE-RELIEF ASSEMBLY FOR A WASHER CHAMBER EP11804162.3 2011-06-29 EP2588812B1 2020-03-18 ROBERT, Maxime; GRAVEL, Claude
145 Fan with dual action check valves EP14151052.9 2014-01-14 EP2757267A1 2014-07-23 Hipsky, Harold W.

An assembly includes a selectively driven fan (46) and a bypass flow passage (149) for bypassing the fan (46). The bypass flow passage (149) communicates with a first check valve (50) to allow air to flow from the bypass flow passage (149) to a downstream location (48). A second check valve (60) allows air driven by the fan (46) to pass into a return passage and return to an inlet of the fan (46) in the event that the discharge pressure from the fan (46) overcomes a spring force associated with the second check valve (60). A heat exchanger pack (20) and an environmental control system (18) for use on an aircraft and a method are also disclosed.

Supply of a liquid fuel or comburent to a combustion chamber (2) of a rocket engine (1) is controlled by a feed valve (14) provided with an obturator (22) mobile between an open position and a closed position of at least one supply pipe (18), which has an inlet (21) that communicates with a tank (13) for containing the liquid component and an outlet (17) that communicates with the combustion chamber (2); the displacement of the obturator (22) from its closed position to its open position being triggered by a pressurized fluid supplied to the outlet (17) of the supply pipe (18).

147 SHEET WITH VALVE-CONTROLLED PRESSURE SYSTEM EP06847059.0 2006-11-21 EP1977656A2 2008-10-08 Chasco Pérez de Arenaza, Juan Carlos

The invention relates to a sheet with a valve-controlled pressure system, having flexible cavities which are interconnected by means of valve devices which have an internal pressure that is greater than that of the flexible cavities surrounding same. When the pressure in any of the flexible cavities exceeds the known internal pressure of the valve devices with which it is interconnected, a fluid passes from said flexible cavity to the adjacent cavities, thereby balancing the pressure of the support. The invention is provided with an alarm and an external system for adjusting the pressures of the valve devices. The invention is mainly intended to be used as a support for feet in general and for diabetic feet, as a seat and to prevent external system for adjusting the pressures.

151 Durchströmventil EP82103236.4 1982-04-16 EP0093783A1 1983-11-16 Brunner, Rudolf

Bei einem Durchströmventil mit einem Strömungsdurchgang, der einen Arbeitsströmungsweg (A) und einen Rückströmungsweg (R) aufweist, ferner mit einem aus einem federbelasteten Schließkörper und einem Ventilsitz bestehenden Druckbegrenzungsventil (18, 20) im Rückströmungsweg, das unterhalb einer bestimmten Druckgrenze den Rückströmungsweg sperrt, und mit einem aus einem Schließkörper und einem Ventilsitz bestehenden Rückschlagventil im Arbeitsströmungsweg, dessen Schließkörper vom Arbeitsdruck unter Freigabe des Arbeitsströmungsweges vom Ventilsitz wegbewegbar ist, ergibt sich ein verhältnismäßig komplizierter Aufbau, da das Druckbegrenzungsventil und das Rückschlagventil, die ja einander entgegengesetzt wirken, voneinander getrennt im Strömungsdurchgang angeordnet werden müssen. Zur baulichen Vereinfachung und zum Erreichen eines großen Durchgangsquerschnitts bei gegebener Außenabmessung des Ventilgehäuses werden beide Strömungswege (A, R) über einen gemeinsamen Ventilsitz (18) geführt und ist der mit dem Ventilsitz zusammenarbeitende Schließkörper (20) aus seiner beide Strömungswege sperrenden Sperrstellung (I) vom Arbeitsdruck in Arbeitsströmungsrichtung (P) in eine erste Offenstellung (II) vom Ventilsitz wegbewegbar, in der er den Arbeitsströmungsweg freigibt, und ist weiterhin der Schließkörper aus seiner Sperrstellung (I) vom Rückströmungsdruck in Rückströmungsrichtung (L) gegen die Kraft der Feder in eine zweite Offenstellung (III) bewegbar, in der er den Rückströmungsweg (R) freigibt.

155 VALVE ASSEMBLY FOR A DIFFERENTIAL PRESSURE SENSOR WITH SAFETY VALVE PCT/SE2011/050662 2011-05-27 WO2012002875A1 2012-01-05 JILDEROS, Daniel

Valve assembly (1) included in a system for measuring differential pressures in a fluid system where the valve assembly includes a differential pressure sensor (12) for registration of differential pressures, a first cavity (22) including a calibrating cone (10) which is displaceable between a measure position and a position for zero point calibration/ flushing through of the valve assembly (1). The valve assembly (1) includes a valve body (7) with two connections (13, 14) and further a second cavity (15) arranged with a safety valve cone (8). The safety valve cone (8) protects the differential pressure sensor (12) against to high differential pressure. This is made by that the safety valve cone (8), by differential pressures higher than a dimensioned value, is moved in direction towards the low pressure side and as a result a passage between high and low pressure side is opened, from the one connection (13), i.e. the high pressure side, to the other connection (14), i.e. the low pressure side, via the second cavity (15) in the valve body (7), and via, in the safety valve cone (8) provided cavities (24) and recesses (25), whereby a pressure equalizing occurs.

One end of a valve assembly (10) has a first check valve arrangement (26) and is positioned in a channel (42) connecting a variable volume reservoir (46) and a second chamber (44). The other end of the valve assembly has a second check valve (38) and is attached to a movable wall (50) of the variable volume reservoir. Each check valve includes an element which opens in response to pressure changes in the variable volume reservoir (46): the first check valve (26) opening in response to pressure increases while the second check valve (38) opens in response to pressure decreases. The valve assembly (10) is bodily movable with the wall (50) of the variable volume reservoir (46) such that the first check valve (26) reciprocates in the channel (42).
