Abstract
Disclosed herein is a linear compressor. In the present invention, a leaf spring is used for an exhale spring to support an exhale valve. As the leaf spring supports the exhale valve by being bended in a predetermined direction, the exhale valve can be stably opened and closed in the predetermined direction. As a space for the exhale spring becomes reduced in an inner exhale cover, a size of an exhale part is reduced, thus making it possible to produce the compact linear compressor. As the leaf spring is comprised of a plurality of overlapped plates, when the exhale valve is opened and closed, the leaf spring is bended, and friction is generated among the plurality of plates. Therefore, a vibration of the exhale valve is decremented by its friction, thus reducing a friction noise.
Claims20
A linear compressor comprising:
- an exhale cover where fluid drained from an opening of a cylinder is discharged;
- an exhale valve to open and close the opening;
- and
- an exhale spring mounted in the exhale cover to elastically support the exhale valve,
- Wherein the exhale spring is a leaf spring.
A linear compressor comprising:
- a hermetic casing;
- a linear motor installed in the hermetic casing;
- a cylinder block set in the linear motor and provided with a cylinder;
- a piston which linearly reciprocates in the cylinder, by means of the linear motor;
- and
- an exhale part located in a front of an opening of the cylinder to discharge fluid compressed within the cylinder,
- Wherein the exhale part further includes:
- an exhale cover where fluid drained from the opening of the cylinder is discharged;
- an exhale valve to open and close the opening;
- and
- a leaf spring mounted in the exhale cover to elastically support the exhale valve.
