Abstract: Cylinder heads of piston compressors, particularly for refrigerating fluids with center suction valves set on the flange of the liner and bearing elastically against the cylinder head cover, forming "liquid anti-surge valve." The backing with elastical setting of the valve (3) on the liner (2) is achieved by means of an intermediary piece (5) in which a control push rod (30) of a load-shedding valve (4) under the thrust of elastic means (16) put out of action during normal run by a reversal thrust of a servo fluid applied through conduits (9) in a bore provided in the intermediary piece (5) on a piston integral with the push rod (30) against said elastic means (16).
