Abstract: A method for fault monitoring of a discharge valve of a condensate drainage means of a pressurized gas system includes a closing step wherein the control circuit triggers a closing movement of the valve element in the direction of the closed position, and/or an opening step wherein the control circuit triggers an opening movement of the valve element in the direction of the open position, and a subsequent step for monitoring the closed or open positions of the valve element. In the step for monitoring the closed position, a non-closed position is detected on the basis of a discharge flow of the pressurized gas, of the condensate or of mixtures thereof in the discharge region or at the valve element. In the step for monitoring the open position, a discharge flow of the pressurized gas, of the condensate or of mixtures thereof in the discharge region or at the valve element is detected.

Abstract: The invention relates to an air compressor having a catalyst that is disposed in a reception block. The reception block is interposed between a valve block and a cylinder cover, comprises an inlet port in the region of a valve block outlet port, and an outlet port in the region of a cylinder head inlet port, so the compressed air exiting the valve block outlet port flows through said catalyst and through the outlet port into the cylinder cover.

Abstract: A vertically directed dryer unit for compressed air, comprising a dryer cartridge which, together with a housing, defines an inlet head area and an outlet head area. A plurality of hollow membrane fibers extend inside the cartridge between the two head areas, the wall material thereof being more permeable with respect to water vapor than air. An outlet valve is provided between the outlet head area and an outlet of the drier unit. Said valve only opens when the pressure in the outlet head area produces sufficient pressure for the provision of purging air. The purging air is fed to the outer surface of the membrane fibers via a throttle element.

Abstract: The present invention relates to a steam trap for draining off condensate from a collecting chamber in which condensate resulting in a pressure gas system is collected, the collecting chamber being pressurized by a gas pressure which, depending upon the operating state of the pressure gas system, may be a negative pressure below the atmospheric pressure, an overpressure above the atmospheric pressure or an atmospheric pressure itself. The steam trap may be separated via an interface into an integral first assembly unit and an integral maintenance assembly unit which comprises the essential wear and tear parts.

Abstract: The invention relates to a hollow fiber separation module comprising an inlet (20) for the gas to be dried, an outlet (22) for dried gas, an access element (26) and a discharge element (28) for circulation gas, and a plurality of hollow fibers which respectively extend from the inlet (29) to the outlet (22) and comprise an inner region which communicates with the inlet (20) on one end of each hollow fiber, and with the outlet (22) on the other end of each hollow fiber. The hollow fibers are wound up in a plurality of layers (40, 42, 44) to form a hollow cylindrical winding. Each layer (40, 42, 44) is inwardly defined by an imaginary cylinder (35, 36, 37) and has a number of hollow fibers which are wound onto the cylinder (35, 36, 37) in a helical manner with an alpha angle of inclination, are located at a distance a from each other, and are arranged on the cylinder in a homogeneously distributed manner. A layer (40) differs from an adjacent layer (e.g.

Abstract: The invention relates to a separating device for separating a first liquid from a second liquid, wherein the first liquid has a lower specific density than the second liquid. The separating device comprises a receptacle with an inside wall, an inlet and an outlet, wherein the inlet is arranged above the outlet, and a separating member made of a permeable filter material that is capable of adsorbing the first liquid and is arranged within the receptacle between the inlet and the outlet and is configured in such a manner that it floats on the second liquid when it is clean, and sinks with the increasing adsorption of the first liquid.

Abstract: A filter for separating contaminants from a gas stream, including (a) a housing having a housing body and a housing head, the housing head having an inlet for the gas stream to be purified, an outlet and a first sealing surface, and (b) a filter element accommodated in the housing, having an element head and an element body having a central element axis and an element interior. The element head has a second sealing surface which cooperates with the first sealing surface. A curved inlet manifold is formed between the inlet and the element interior. The inlet manifold is embodied partly in the housing head and partly in the element head such that the first and second sealing surfaces contact in a sealing plane at a 90° to 60° angle to the element axis. A radially arranged seal is provided on the sealing plane, forming one of the sealing surfaces.

Abstract: The invention relates to a method of draining condensate from a reservoir that communicates with a trap via a drain pipe. The reservoir is subjected to a gas pressure p(reservoir) that can be below atmospheric pressure p(air) or above atmospheric pressure p(air). The method involves the following steps: a) collecting condensate in the reservoir, b) acquiring the fill level by means of a level meter, c) providing a control pressure p(control) which, in any operating conditions of the compressed gas system, is above the pressure p(reservoir) in the reservoir and above atmospheric pressure p(air), d) providing, under control, a control conduit input of an exhaust valve, which is assigned to the reservoir and is intended to drain the condensate collected in the reservoir, with a pressure p(input).

Abstract: The dryer for compressed air comprises a filter bowl (20), which has an inlet (22) for damp compressed air, an outlet (24) for dried compressed air, a scavenging air inlet (26) and a scavenging air outlet (28). A membrane is accommodated in the filter bowl (20). The membrane lets selectively water steam flow through and has two sides. One side of the membrane is stroked by the compressed air, while scavenging air flows on the other side of the membrane. A feeder pipe (32) is provided, through which dried compressed air coming from the outlet (24) is fed into the scavenging air inlet (26). A closing device (34, 36, 38) is arranged in the feeder pipe (32) and has a closed position. The closed position depends on the consumption of compressed air in such a way that more or less scavenging air is made available when more or less compressed air is taken by a consumer device, operated by dried compressed air.
