Abstract
A linear compressor may include a driving coil, a mover, a piston, and a coupling. The mover may be positioned adjacent the driving coil. The driving coil may be operable to reciprocate the mover relative to the driving coil. The piston may have a piston head and a cylindrical side wall. The inner surface of the cylindrical side wall may define a ball seat. The coupling may extend between the mover and the piston. The coupling may include a flex mount and a ball nose.
Claims18
A linear compressor, comprising:
- a driving coil;
- a mover positioned adjacent the driving coil, the driving coil operable to reciprocate the mover relative to the driving coil;
- a piston having a piston head and a cylindrical side wall, an inner surface of the cylindrical side wall defining a ball seat;
- and
- a coupling extending between the mover and the piston, the coupling comprising:
- a flex mount extending between a first end portion and a second end portion, the flex mount connected to the mover away from the first end portion of the flex mount,
- a ball nose positioned at the first end portion of the flex mount, the ball nose contacting the piston at the ball seat of the piston, and
- a freeze ring positioned at the first end portion of the flex mount radially inward from the ball nose to guide variable axial alignment of the ball nose,
- wherein the flex mount defines a frustoconical edge at the first end portion in contact with a rearward edge of the ball nose.
