摘要： A valve, for example for controlling a clearance at a tip of turbine blades, includes a piston and a supply mechanism supplying fluid under pressure to cause the piston to move inside a hollow body, and a mechanism detecting a position of the piston, including a shut-off element that moves as one with the piston and is mounted such that it can move in a fluid passage between two positions, open and closed respectively, the fluid passage connecting the supply mechanism to a pressure sensor that generates an output signal representative of the position of the piston of the valve.

摘要： A valve assembly (1) 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) with a calibrating cone (10) displaceable between measuring and a zero point calibration/flushing position. The valve assembly (1) includes a valve body (7) with two connections (13, 14) and a second cavity (15) arranged with a safety valve cone (8) which protects the differential pressure sensor (12). The safety valve cone (8), by differential pressures higher than a dimensioned value, is moved in a direction towards the low pressure side and, as a result, a passage between high and low pressure side is opened, from one connection (13) to the other connection (14) via the second cavity (15) and via provided cavities (24) and recesses (25) in the safety valve cone (8), whereby a pressure equalizing occurs.

摘要： A device is provided for handling animal waste gas and suppressing global warming. The device includes a hood, a feces tube that is provided with a first one-way valve, and at least one waste gas tube that is provided with a second one-way valve. The waste gas tube has an end connected to a container. When an animal expels waste gas and fecal matter, the fecal matter is allowed to drop into the feces tube and passes through the first one-way valve. The waste gas is conducted through the second one-way valve into the container for storage. As such, the waste gases expelled from cows and horses can be re-used in order to reduce pollution caused thereby, increase energy sources, and suppress the greenhouse effect of the Earth.

摘要： The present application is directed to a gas-generating apparatus and various pressure regulators or pressure-regulating valves. Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The transportation of a first fuel component to a second fuel component to generate of hydrogen occurs automatically depending on the pressure of a reaction chamber within the gas-generating apparatus. The pressure regulators and flow orifices are provided to regulate the hydrogen pressure and to minimize the fluctuation in pressure of the hydrogen received by the fuel cell. Connecting valves to connect the gas-generating apparatus to the fuel cell are also provided.

摘要： Micro check valves having a free-floating member for controlling flow of fluid in microfluidic and biomedical applications and methods of fabrication. A micro check valve includes a valve seat, a valve cap that contacts the valve seat and an untethered floating member that can move between the valve seat and the valve cap. Certain micro check valves have zero cracking pressure and no reverse leakage. Certain other valves may be configured to permit flow of fluid within a pressure range. The floating member can be solid or define an orifice, and the valve seat can have one or two levels. Valves can be configured to allow fluid to flow when the floating member is pushed by fluid against the valve cap or against the valve seat. The valve seat may be silicon or another material that is compatible with micromachining processes, and the valve cap and the floating member may be a polymer such as Parylene.

摘要： The invention relates to a hydraulic valve arrangement which is used, in particular, for a mobile machine and which has a valve housing (10) having a feed channel (34), having an outlet channel (42) and having a consumer channel (39) and has a valve bore (11) which cuts into the channels. In the valve bore (11), a valve slide (12) can be moved axially from a neutral position in at least one direction into a working position, by way of which valve slide (12) the fluidic connections between the channels can be controlled. Moreover, there is a pressure-relief and feed valve (45, 47), by way of which the pressure in the consumer channel (39) can be limited by throttled discharge of pressure fluid into the outlet channel (42) and pressure fluid can be fed from the outlet channel (42) into the consumer channel (39). The invention is based on the object of designing a hydraulic valve arrangement of this type in such a way that low manufacturing costs and a small overall size are possible. According to the invention, the object which is aimed at is achieved by the pressure-relief and feed valve (45, 47) being accommodated in a hollow space of the valve slide (12).
