Abstract: The compressor comprises a valve plate, to be affixed to a compressor block, and a suction valve (V) formed by a spacer body, having a median opening and a flexible vane, which has a fixing end portion provided with a contour, symmetrical or asymmetrical, in relation to a longitudinal axis (X) of the flexible vane and which presents peripheral edge portions to be seated against respective inner edge portions of the median opening for restricting coplanar, linear and angular displacements of the flexible vane in relation to the spacer body upon seating the flexible vane against the valve plate, in the interior of the median opening.
