摘要： A piston vacuum pump comprises a cylinder (14) and a piston (12) that forms a compression chamber (28) with the cylinder (14). The piston (12) oscillates in the cylinder (14) with a compression stroke and an intake stroke. In a side wall (16) of the cylinder (14), a gas inlet (30) is provided, the gas inlet (30) being closed by the piston (12) at the beginning of the intake stroke and open at the end of the intake stroke. Further, an equalizing conduit and a valve are provided through which gas from the gas inlet (30) flows into the compression chamber (28) at the beginning of the intake stroke. This provides a simple arrangement of an equalizing conduit with a valve. The piston substantially forms the equalizing conduit and the valve. Thereby, the valve can act in the region of the piston end wall so that the dead volume is minimized.

摘要： Two-shaft vacuum pumps are normally driven by asynchronous motors. The asynchronous motor rotors configured as cage rotors are relatively heavy and long and must therefore be supported by supporting bearings. It is an object of the invention to provide a two-shaft vacuum pump with a simplified drive motor. The two-shaft vacuum pump (10) according to the invention comprises a synchronous motor as a drive motor (20), wherein the motor rotor (26) is permanently excited. Permanently excited motor rotors (26) are smaller and of lighter weight such that rotor supporting bearings can be omitted. Thus, the problems associated with cooling and lubrication of the supporting bear-ings are eliminated either.

摘要： The invention first relates to an air filter attachment (4) for a turbomachine, in particular a side channel compressor, comprising a housing, comprising a filter material (8) arranged in a housing interior, and comprising an inlet (9) and an outlet (10) which are formed in the housing, which have a free opening cross section, and through which air is suctioned. The aim of the invention is to advantageously design a turbomachine comprising an air filter attachment. This is achieved in that the housing interior that has the filter material (8) extends laterally relative to the opening cross section of the inlet (9) and/or the outlet (10) in a non-uniform manner and in any case in a direction by a magnitude of 1½ or more times the dimension from a central axis (M) of the respective opening cross section to a periphery of the opening cross section in the direction. The invention further relates to a turbomachine, in particular a side channel compressor, comprising such an air filter attachment. Additionally, the invention relates to a filter part (12, 19) consisting of a pleated filter material (8) or a circumferential filter wall (21) which is connected to a base part (22) and which consists of a filter material.

摘要： An oscillating-piston drive for a vacuum pump (1) with a piston (2), which presents has two piston sections (3,4) and an intermediate zone provided with a drive magnet (11). Cylinder sections (8, 9) slidingly receive the piston sections (3, 4). An annular recess (12) is defined between the cylinder sections (8, 9) at a central yoke (19). The recess provides space for movement of the drive magnet (11). An electromagnetic drive which surrounds the piston (2) includes yoke components (17, 18, 19) and coils (15, 16) situated to the sides of said central yoke. Negative influences on the delivery rate of the pump are reduced by a can (34) which delimits the recess (12) peripherally or by controlling the current supply to the coils, such that only one coil conducts current at a time.
