摘要： A multi-stage pressure regulation system, device and associated methodology for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, and an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core.

摘要： One aspect relates to an engine including a working system, having a first piston-cylinder system, comprising a working piston and a working cylinder. The working piston divides the working cylinder into a first working cylinder portion and a second working cylinder portion, a valve system, having a first valve connection and a valve element. The valve system and the working system are connected in a gas conducting manner, the first valve connection can be connected to a negative pressure source, and the valve element is movably arranged in the valve system such that, in a first valve position, the valve element connects the first valve connection to the first working cylinder portion, and, in a second valve position, connects the first valve connection to the second working cylinder portion in a gas conducting manner.

摘要： The protection device has a valve and a valve actuator, able to move the valve to a closed position when a pressure upstream of the valve exceeds a predetermined threshold pressure. The valve actuator includes a biaiser, to maintain the valve in an open position; an actuation mechanism, to move the valve to the closed position, the actuation mechanism with a fluid sampling passage to fluidly connect the flow line to a fluid actuated surface of the actuation mechanism. At least a rupture element preventing the passage of fluid from the flow line when the pressure upstream of the rupture element is lower than the threshold pressure, the rupture element being able to break at the threshold pressure.
