Abstract

The valve for a refrigerator piston compressor has its seating incorporated in a flat rectangular plate (10) with a set of holed through it, with a main discharge hole (11) through it, located in the middle of a kidney shaped depression (16) in the top surface, covered by a curved leaf spring blade (13) which in turn is covered by a half moon shaped resilient stop finger (14). The curve of the kidney shaped groove matches the edge of the blade, and slopes inwards towards the hole (11) through its middle. Following the contour of this kidney shaped depression, is a groove (18) in the upper surface, forming the boundary of this sloping edge (16).
