A two-way wobble plate compressor, comprising: a cylinder block (); a two-way piston () capable of reciprocating within a cylinder bore () of the cylinder block (); a drive assembly () driving the two-way piston (), the drive assembly () including a drive shaft (), a rotor () fixedly connected with the drive shaft (), and an annular wobble plate () fitting with the rotor (); the rotor () has an inner surface () for fitting with the annular wobble plate (), the inner surface () include a first inner surface () and a second inner surface (), which are oppositely arranged, and a rotor contact surface (); the wobble plate () is partially encircled within the inner surface () of the rotor (), and includes a first peripheral portion (), a second peripheral portion (), and a wobble plate contact surface (); a first bearing () is provided between the first inner surface () and the first peripheral portion (), a second bearing () is provided between the second inner surface () and the second peripheral portion (), and a third bearing () is provided between the rotor contact surface () and the wobble plate contact surface (). The two-way wobble plate compressor of the present invention may significantly reduce friction loss.

Two-way wobble plate compressor

A two-way wobble plate compressor, comprising: a cylinder block (); a two-way piston () capable of reciprocating within a cylinder bore () of the cylinder block (); a drive shaft () driving the two-way piston (); 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 () 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.
