Abstract
A valve plate assembly is provided with a valve restraint for maintaining a valve within a recessed portion of the valve plate. The valve restraint further includes an irregular surface which contacts the surface of the valve when the assembly is in use, for example, in a compressor. The irregular surface may include through-holes at least partially through the surface which contacts the valve or may be a textured surface which contacts the valve during use. The valve plate includes a recessed portion having guides for receiving notched sections in the sidewalls of the valve and valve restraint.
