Abstract:
1. A compressor comprising: a cylinder head defining a chamber, and a valve plate mounted at an end of said cylinder head; a piston reciprocating within said cylinder head toward and away from said valve plate; an inlet valve for allowing flow of a fluid into said chamber; a discharge valve for selectively allowing flow of a compressed fluid outwardly of said chamber, said discharge valve being positioned at an opposed end of a discharge port from said chamber, said discharge port having a first cross-sectional area, said discharge valve being flexible away from said discharge port in response to a force from the compressed fluid, and said discharge valve seating on a valve seat on said valve plate, an area defined inwardly of said valve seat is greater than said first cross-sectional area, said area defined inwardly of said valve seat being non-cylindrical; said valve seat defining a shape inward of said valve seat which is distinct from a shape of said area of said discharge port; and said valve seat having a central circular area with two opposed ears extending radially outwardly from said circular area to define said increase in area over said first cross-sectional area.
