摘要： A gas inlet valve (1) for a compressor (64), comprising: a housing (2); a valve device (6) arranged between a gas inlet portion (3) and a gas outlet portion (4), a valve body (57) resting against a valve seat (56) in a sealing manner when the valve device (6) is in a closed operating state, and the valve body (57) being lifted from the valve seat (56) when the valve device (6) is in an open operating state; a piston device (42) which comprises a first piston portion (43) and a second piston portion (44) which is different from the first piston portion (43), the first piston portion (43) being displaceably guided in a first cylinder portion (22) of the housing (2) and the second piston portion (44) being displaceably guided in a second cylinder portion (27) of the housing (2) which is different from the first cylinder portion (22); and a piston rod (38) which is displaceably mounted in the housing (2) and mechanically couples the valve body (57) of the valve device (6) to the piston rod (38), a fluid line (39) putting a first cylinder chamber (49) of the first cylinder portion (22) in operative fluid communication with the gas outlet portion (4), it being possible to apply a control pressure to a second cylinder chamber (52) of the second cylinder portion (27) in order to lift the valve body (57) from the valve seat (56). A rotary compressor comprising a gas inlet valve (1) of this type and a method for operating a compressor (64), in particular a rotary compressor, comprising a gas inlet valve (1) of this type.

摘要： The invention relates to a method for the analysis of the compressed-air supply security of a compressed-air system which comprises one or more compressed-air generators (C1, C2) and supplies one or more compressed-air consumers via a compressed-air network (9),characterized in that a time course of the maximum delivery volumetric flow rate MDVF(t) is recorded, estimated or calculated, that a time course of the consumption volumetric flow rate CVF(t) is recorded, estimated or calculated, and that for the analysis of the compressed-air supply security the time course of the maximum delivery volumetric flow rate MDVF(t) and the time course of the consumption volumetric flow rate CVF(t) are automatically offset against each other over an analysis period.

摘要： The invention relates to a screw compressor comprising a compressor housing (11) having two rotor screws (1, 2) mounted axially parallel therein, which mesh with each other in a compression space (18), can be driven by a drive and are synchronized with each other in their rotational movement, wherein the rotor screws (1, 2) each have a single-part or multi-part base body (24) with two end faces (5a, 5b, 5c, 5d) and a profiled surface (12a, 12b) extending therebetween, and shaft ends (30) projecting beyond the end faces (5a, 5b, 5c, 5d), wherein at least the profiled surface (12a, 12b) is formed in multiple layers, comprising a first, inner layer (3) and a second, outer layer (4), wherein the first, inner layer (3) and the second, outer layer (4) both comprise or are formed from a thermoplastic synthetic material, wherein particles (25) or pores (32) supporting a running-in process are embedded in the second, outer layer (4) and the thermoplastic synthetic material defines a matrix for receiving the particles (25) or for forming the pores (32).
