    摘要： A cold start valve for a hydraulic circuit has a valve slide with two counteracting control faces. It is possible to load a first control face with a control pressure and to load a second control face with a feed pressure. In addition, the first control face is loaded with the spring force of a valve spring. A damping space is configured to damp a stroke movement of the valve slide. The damping space is delimited by a damping face formed on the valve slide and oriented in accordance with the first control face. The damping face is configured to be loaded via the damping space with a damping pressure to damp the stroke movement. The damping space is connected in a throttled manner to a pressure space. The second control face of the valve slide is configured to be loaded with the feed pressure via the pressure space.

    摘要： A gas pressure regulator for use with gas delivery systems is provided. The gas pressure regulator includes, in one form, an inlet with an entry portion and a bottom portion. A pocket is disposed proximate the bottom portion of the inlet, and a cavity is disposed within a central portion of the gas pressure regulator. A guide is disposed within a lower portion of the cavity, and a flow of gas through the gas pressure regulator extends through the inlet, changes direction to flow through the cavity, and the flow of gas changes direction to impact the guide prior to flowing through the cavity. The pocket and the guide reduce the amount of particles capable of reaching internal components of the gas pressure regulator, resulting in low sensitivity and high fault tolerance to ignited particles coming through the gas pressure regulator in the event of accidental particle contamination.

    摘要： A regulator for maintaining a constant partial vacuum in a region, such as in a piece of process equipment or a fume hood. The regulator includes a path, through which fluid passes from the region to the vacuum source, and a movably mounted piston having a frontal face, which is exposed to fluid in the path, and a distal face, which is exposed to a reference pressure, such as the pressure of the environment in which the equipment is located. The piston is disposed in the path so that the piston may constrict the path at a constriction point. Fluid in the path upstream of the constriction point exerts a pressure on the frontal face of the piston that tends widen the path at the constriction point. The piston is mounted so that the weight of the piston exerts a force on the piston in a direction that tends to widen the path at the constriction point. A force is exerted on the piston, preferably by a spring under compression, in a direction that tends to narrow the path at the constriction point. A buffering gas, introduced to the area between the piston's skirt and the piston mounting structure, may be used to keep noxious fumes from backing up into the environment and/or to provide an efficient bearing.

    摘要： A fluidic pressure regulator for maintaining a system pressure over a range of ambient pressures, which includes a pressure sensing circuit comprised of a bridge network of orifice and laminar flow restrictors providing an output error signal for all pressures except the unique null pressure at which the pressure drop across an orifice restriction and a laminar flow restriction are equal. A downstream orifice is provided which operates in the sonic regime to eliminate the effects of ambient pressure shifts on the null point, while the error signal is used with a flow controller to maintain the system pressure at this null point. In a second version, the effects of temperature on the null point are eliminated by means of a temperature controlled variation of the area of the downstream orifice.
