Taper fit mounting of stator in free piston compressor motor

摘要

Fig 3 illustrates a section of an exemplary linear compressor including a piston 22 sliding within the bore 12 of a cylinder 1, a connecting member 30, 32, 45, 21 connecting the piston to the main spring 16, the main spring being mounted to the cylinder, and the stator 15 of a linear electric motor that has an air gap through which the armature pole 17 of the motor that is located along the connecting member passes. The stator includes several parts opposed across the air gap, for example 2 parts, and Fig 7 illustrates an exemplary mounting of the stator parts on the cylinder part. The cylinder part is provided with a tapered seat 105, 106 for each stator part, and each stator part is provided with a matching taper 101, 102 and is engaged into the tapered seat.
