Abstract
A valve device for a compressor is improved to suppress noise and a decrease in compressor efficiency caused by pressure pulsations, and also to prevent degradation in compressor performance by ensuring durability. In a valve device of a reed valve structure including: a valve hole 103a or 103b formed in a valve plate 103; a valve seat 103e formed in an outer peripheral portion of the valve hole so as to protrude in a boss shape to a groove 103f formed around an outside thereof; and a valve body 151 having a proximal end 151A connected to the valve plate and a distal end 151B allowed to freely come into and out of contact with a seat surface of the valve seat, a plurality of ribs 103g extend radially from a peripheral wall of the valve seat to an outer peripheral wall of the groove.
Claims5
A valve device for a compressor, which has a reed valve structure, comprising:
- a valve plate in which a valve hole opened and closed to draw or discharge a refrigerant is formed;
- a valve seat formed in an annular shape in an outer peripheral portion of the valve hole in the valve plate, wherein a groove is formed around an outside of the valve seat;
- and
- a valve body having a proximal end connected to the valve plate and a distal end allowed to freely come into and out of contact with a seat surface of the valve seat,
- wherein at least one rib extends radially outwardly from the portion of the valve seat corresponding to the distal side of the valve body, and
- wherein a height of the at least one rib from a bottom of the groove is less than a height of the seat surface of the valve seat from the bottom of the groove.
