Abstract
A compressor assembly includes a shell which defines a discharge chamber. A discharge valve assembly is attached to the shell in communication with the discharge chamber. The discharge valve assembly includes a stamped or coined valve seat, a drawn tubular element and a stamped valve member. The stamping, drawing and coining operations used to manufacture the discharge valve assembly significantly reduce the manufacturing costs for the discharge valve assembly.
