  • Air compressor with ramped head deck
    Patent number: 11971026
    Abstract: An improved air compressor is provided. The air compressor includes a cylinder block having a head deck that defines a piston bore for reciprocal movement of a piston therein. The head deck further includes first and second ramped surfaces that slope downward toward the peripheral edge of the piston bore. A valve plate is in direct contact with the upper surface of the head deck, the valve plate having a leaf valve. During an intake stroke of the piston, the leaf valve deflects downward into direct engagement with the first and second ramped surfaces. Because the air compressor lacks a lower gasket between the valve plate and the head deck, the cost and assembly time associated with the lower gasket are eliminated.
