Abstract
A suction valve for an axial piston compressor has a leaf spring fixed at one end, which spring at one end is fixed with a fixed portion between valve plate and cylinder block, at its other end covers over the suction valve opening with a closure portion and has an intermediate portion connecting these portions. The intermediate portion is located substantially outside the cylinder cross-section. A stop for the suction valve leaf spring is arranged in the region of the cylinder wall facing the fixed portion. This produces an optimum filling of the cylinder and thus an improvement in the efficiency of the compressor, as is especially desirable for refrigeration compressors.
