Abstract: A surge prevention valve may be used to prevent the formation of an initial surge of high pressure. The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice.

The controlled pressurization of the gas through the orifice delays the time during which the gas reaches full recompression. The valve may be further provided with a vent for venting pressurized gas away from a nominally closed top surface of the lower valve element.

Abstract: In a pressure fluid control valve device, the fluid exhausted from an internal combustion engine flows through a pair of paths selectively or simultaneously. Each of the paths is opened and closed by a butterfly valve fixed to a valve shaft. A coupling for connecting the valve shafts across the paths comprises a slitting recess and a projection provided at the opposing ends of the valve shafts respectively. The direction of the surface of the recess and the projection is set to within 30 degrees with respect to the direction of the surface of the valve disc fixed to the valve shaft having the recess.

Abstract: A novel metering valve is used to split the streams in which a continuous fluid stream passes unregulated through the valve along a primary flow path. A second stream is formed by passing a small portion of the fluid in the primary flow path through a passage in a valve seat.

Both fluid from the unregulated primary flow path and through the metered flow path flow simultaneously from the valve. The metering valve of the invention has particular use in processes for dividing a condensed distillate stream into a product stream and a reflux stream.

Abstract: An exhaust system for a gas turbine has a main axial duct which feeds a heat exchanger to make use of the residual heat in the exhaust gases. The heat exchanger may in some circumstances be overloaded so a branch duct is taken from the main duct conventionally by means of a T-junction with a flap valve closing off either the main (axial) outlet or the branch outlet. The branch duct is then taken to an exhaust stack. Turbulence at the T-junction causes poor flow upstream of the junction and corresponding poor turbine performance. The invention provides a junction in which the main axial duct (1) passes smoothly through a bypass chamber (15) which surrounds the axial duct (1). Slots (17) in the axial duct within the chamber (15) permit passage of the exhaust gases to the bypass duct (19). Rotating blade valves (13 and 23) in the two duct outlets control the relative flow of exhaust to heat exchanger and exhaust stack.

The coupling is made via a coupling rod articulated on the two flaps. To achieve a pivoting angle of the same amount on both flaps, the articulation points are so determined that, on the one hand, the radius of the circular paths described by them during the pivoting of the flaps is of equal size and, on the other hand, during the pivoting of the flaps, an imaginary effective straight line respectively connecting the two articulation points rotates about an imaginary center of rotation located approximately in the middle between the two pivot axes.
