  • Patent number: 10253764
    Abstract: A two-way wobble plate compressor, comprising: a cylinder block (100); a two-way piston (200) capable of reciprocating within a cylinder bore (110) of the cylinder block (100); a drive shaft (310) driving the two-way piston (200); a bearing unit, including a plurality of contact balls and an inner ring and an outer ring fitting with the plurality of contact balls, and having a central plane (P-P) angled to a perpendicular plane (I-I) of the drive shaft; wherein said drive shaft (310) is sleeved in the inner ring of the bearing unit, and is fixed to the inner ring; the outer ring of said bearing unit is coupled to the two-way piston, and when the drive shaft rotates, the two-way piston is driven via the bearing unit to perform reciprocating motion. The two-way wobble plate compressor of the present invention has a compact design, and may significantly reduce friction loss.
