Abstract
A small single cylinder hermetic refrigeration compressor has a flat valve plate extending across the end of the cylinder. A discharge port is formed in the valve plate with a spherical valve seat and a spherical poppet member is moveable to and from the valve seat. A flat leaf spring and valve stop member fit over the poppet to control its motion and the spherical head of the popper, when closed, extends beyond the surface of the valve plate in alignment with a mating recess on the piston head to minimize the clearance space of the compressor.
