High efficiency plate valve for reciprocating compressor

The valve seat for a compressor plate valve comprising:

• a circular top valve surface defining a plurality of linear extending fluid ports each fluid port having ends spaced a predetermined distance inwardly from an outer edge of said top valve surface,
• wherein there are six linear fluid ports with a first and second fluid port extending chordally and parallel to each other on opposite sides of the valve seat center, and said first and second ports being a predetermined distance from the valve seat center;
• third and fourth fluid ports extending chordally and parallel to each other on opposite sides of the valve seat center, and said third and fourth ports being a predetermined distance from the valve seat center, and
• fifth and sixth fluid ports extending radially from opposite sides of said valve center and spaced a predetermined distance from said valve center.

A valve plate for a compressor plate valve comprising:

• a flat bottom surface,
• a plurality of linear extending ports spaced a predetermined distance apart and spaced a predetermined distance from the periphery of said valve plate;
• and
• a plurality of linear extending projections extending from a top surface of said plate.

A circular vestial guard for a compressor plate valve comprising:

• an annular flat rim,
• a central arm diametrically extending between said annular rim,
• an irregular shaped mounting orifice formed in a center of said central arm,
• said central arm center being a predetermined distance below said annular rim, and
• a pair of truncated step surfaces extending inwardly from opposite sides-of said annular rim.

In a compressor suction or pressure plate valve having a seat member and a movable plate member comprising:

• said seat member having a plurality of linear fluid passage seat ports therethrough;
• said movable plate member having a surface area for juxtaposed sealing engagement with said seat ports, said plate member having a plurality of linear fluid passage plate ports;
• and
• at least one projection integrally formed on said plate member and extending outwardly from said plate member in a direction away from said plate member for receiving a resilient flat spring biasing said plate member against said seat ports to seal said seat ports.
