  • Patent number: 12163908
    Abstract: A moisture measuring device for gases, in particular compressed gases, compressed air and the like, for moisture content detection in a gas supply system, includes a gas sampling input for the test gas which is connected to the gas supply system. A separate gas channel used only for the moisture measurement branches off from the gas sampling input. The separate gas channel is connected with a measuring cell in which a dew point sensor is arranged. A drying cell with a drying agent is connected downstream of the measuring cell. The drying cell is substantially hermetically sealed against the outside environment. Lastly, the output side of the drying cell is connected to an outlet channel leading to the outside environment. A gas supply system may have the form of a compressed gas system, a compressor station, a storage system and the like.

  • Publication number: 20230106998
    Abstract: The present invention relates to a filter unit (10) for a compressor, comprising a housing (12) with an inlet (14) and an outlet (28) for gas to be compressed, a particle pre-filter (16) arranged downstream of the inlet (14) in the flow direction of the gas to be compressed, an ultraviolet irradiation unit (22) which is configured to emit ultraviolet light and is arranged downstream of the particle pre-filter (16) in the flow direction of the gas to be compressed, and a ballast (40) which is configured and arranged to control the ultraviolet irradiation unit (22). The filter unit (10) is designed in such a way that the gas to be compressed which is fed in at the inlet (14) first passes through the particle pre-filter (16), is then irradiated by the ultraviolet irradiation unit (22) and can finally be fed to the compressor through the outlet (28). The invention also relates to a compressor comprising such a filter unit (10) and to a method for compressing breathing air using such a compressor.

  • Patent number: 9115821
    Abstract: A condensate valve for condensate that is connectable to the inlet side of at least one oil/water separator of a compressor. The condensate valve is triggered for opening and closing via a blocking element. The outlet of the condensate valve discharges directly into a condensate collecting tank. The condensate valve also forms a pressure reducer for reducing the pressure of the outflowing condensate and discharges directly to the condensate collecting tank. Preferably, the condensate valve comprises a movable piston which can be pressed against a small-diameter opening of the valve seat when the condensate valve is closed by a blocking element. The piston has a larger cross-sectional area at its outlet side than at its inlet side on which condensate acts via an overflow line when the condensate valve has been opened. The overflow line can be formed by at least one through channel which extends axially through the piston.

  • Patent number: 6776813
    Abstract: A device for liquid separation for drying and cleaning of compressed gases, which is intended, especially, for compressed air and breathing air, and in which the design is such that a centrifugal liquid separator is located axially upstream of a filter with a filter cartridge in the tank of the device. In the interior of the tank there is the centrifugal liquid separator with an assigned separation space and a condensate liquid collection space axially underneath the filter cartridge of the filter. The bottom of the filter cartridge can form the boundary wall of the separation space of the centrifugal liquid separator. Between the outside wall of the filter cartridge of the filter and the inside wall of the tank there is a narrow gap in which the compressed gas, after leaving the centrifugal liquid separator, rises high along the filter cartridge as far as the opposite entry into the filter. In this area, further post-separation or fine separation can take place.

  • Patent number: 5399073
    Abstract: A compressor unit that has a compressor component and a condensate filter that is used to precipitate water and oil condensed from a compressed gas stream. For the environmentally friendly disposal of the condensate, a filter device containing a filter material is arranged so that a warm air stream entering the filter device after passing through the condensate filter condenses the water in the filtrate stream. The condensate is soaked up in the filter device by the filter material and, with the help of the air stream, which can be the warmed outgoing air of a cooling device of the compressor component, the water contained in the condensate is evaporated, while the oil-containing components of the condensate are adsorbed in the filter material for subsequent disposal. The filter material is preferably placed in the filter device in the form of filter elements arranged preferably in several rows behind one another at predetermined distances in the direction in which air flows through.

  • Patent number: 5152677
    Abstract: A dry-running reciprocating compressor which has a drive mechanism with a crankcase, in which at least one crankshaft is mounted to rotate in bearings. The drive mechanism is operatively connected with at least one piston-cylinder arrangement of the compressor to compress air to the desired compression pressure. The intake air to be compressed is used for interior cooling of the drive mechanism, and for this purpose, the intake air is conducted through a filter into the interior of the crankcase. For specific cooling of especially critical parts and areas of the components and units in the interior of the crankcase, additional air conducting devices, such as air baffles, fins or the like can be provided. Preferably, the reciprocating compressor has three stages.

  • Patent number: 5096399
    Abstract: A rotor pair for a high-pressure screw compressor having main and secondary rotors, the main rotor having essentially convex teeth arranged outside its reference circle and the secondary rotor having essentially concave teeth arranged inside its reference circle. The distance between the axes of the rotors, which limits the size of the possible bearings, is enlarged only by increasing the number of teeth and the diameter of the secondary rotor so that it is larger than the main rotor.

  • Patent number: 4856565
    Abstract: A protective enclosure device for filling tanks with compressed gas provides a cylindrical enclosure within which a tank may be placed and connected to a filling line, and which can, thereafter be closed by a closure arrangement that is equivalent in design to a cannon breech block from the standpoint of its ability to resist the explosive forces of an uncontrolled tank rupture. The walls of the enclosure are not only sufficiently thick to resist rupturing thereof, but are sufficiently heavy to absorb all of the dynamic reaction forces of an explosive tank rupture. Venting of the enclosure is provided at a rate which will prevent room over-pressurization and a resulting potential damaging of windows, doors, and other structures. The device is constructed to function in a fully automatic manner employing electromechanical and pneumatic devices.
