Piston compressor

A piston compressor, comprising:

• a crankshaft comprising a crank pin, a first crank web and a second crank web, said crank pin having a conically tapered end section and a crank pin longitudinal axis, said first crank web having a conically tapered recess, said conically tapered recess receiving at least a portion of said conically tapered end section, said first crank web comprising a first crank web adjustment structure, said first crank web adjustment structure comprising a first crank web adjustment structure surface, said first crank web adjustment structure surface being located at a radially spaced location from at least a portion of said first crank web with respect to said crank pin longitudinal axis, said second crank web comprising a second crank web adjustment structure, said second crank web adjustment structure comprising a second crank web adjustment structure surface, said second crank web adjustment structure surface being located at a radially spaced location from at least a portion of said second crank web with respect to said crank pin longitudinal axis;
• a piston connected to said crankshaft, said crankshaft comprising another crank pin and another crank web, said another crank pin having another conically tapered end section, said another crank web having another conically tapered recess, said another conically tapered recess receiving at least a portion of said another conically tapered end section, wherein said first crank web adjustment structure surface and said second crank web adjustment structure surface are arranged in a same plane with said first crank web aligned with said second crank web, said first crank web adjustment structure surface comprising a first portion, a second portion and a third portion, said first portion being parallel to said third portion, said second portion being perpendicular to said first portion and said third portion, said second crank web adjustment structure surface comprising a second crank web adjustment structure surface first portion and a second crank web adjustment structure surface second portion, said second crank web adjustment structure surface first portion being perpendicular to said second crank web adjustment structure surface second portion, said first crank web adjustment structure and said second crank web adjustment structure defining a means for aligning said first crank web with said second crank web.

A piston compressor, comprising:

• a crankshaft comprising a first part, a second part, a third part, a first adjustment structure and a second adjustment structure, said first part comprising an outer surface, said outer surface defining a conically tapered end portion, said second part having an inner surface and a second part outer surface, said inner surface defining a conically tapered recess, at least a portion of said conically tapered end portion being inserted into said conically tapered recess to form a cone connection, wherein said first part is connected to said second part via at least said cone connection, said third part being connected to said first part, said first adjustment structure being connected to said second part, said first adjustment structure comprising a first adjustment structure surface, said first adjustment structure surface being located at a spaced location from at least a portion of said second part outer surface, said second adjustment structure being connected to said third part, said third part having a third part outer surface, said second adjustment structure comprising a second adjustment structure surface, said second adjustment structure surface being located at a spaced location from at least a portion of said third part outer surface, wherein said first adjustment structure and said second adjustment structure define an alignment indication means for indicating an alignment of said third part with said second part;
• a piston connected to said crankshaft, said first part comprising a first crank pin and a second crank pin, said second part comprising a second part crank web, said first crank pin comprising said conically tapered end portion, said second part crank web comprising said conically tapered recess, said crankshaft comprising a third part crank web, said second crank pin having a second conically tapered end section, said third part crank web having a second conically tapered recess, at least a portion of said second conically tapered end section being inserted into said second conically tapered recess to form a second cone connection, wherein said second crank pin is connected to said third part crank web via said second cone connection, wherein said first adjustment structure surface and said second adjustment structure surface are arranged in a same plane with said second part aligned with said third part, said first adjustment structure surface comprising a first portion, a second portion and a third portion, said first portion being parallel to said third portion, said second portion being perpendicular to said first portion and said third portion, said second adjustment structure surface comprising a second crank web adjustment structure surface first portion and a second crank web adjustment structure surface second portion, said second crank web adjustment structure surface first portion being perpendicular to said second crank web adjustment structure surface second portion.
