ABSTRACT:
Disclosed herein is a discharge valve for a compressor. The discharge valve comprises a valve plate for opening or closing a discharge port, a valve spring positioned downstream from the valve plate and adapted to provide elasticity to the valve plate, and a retainer positioned downstream from the valve spring and adapted to limit a maximum displacement of both the valve plate and the valve spring. The valve spring has a fluid-passage hole for the passage of fluid discharged from the discharge port. With such a configuration, the discharge valve can not only reduce flow loss and overshooting loss of the fluid, but also minimize backflow of the discharged fluid, resulting in an improvement in performance of the compressor.
