The modification of the suction holes of the valve plate would increase the refrigerant flow rate of the compressor. The modified suction holes (11 and 12) are specially designed to have tapering form with the larger diameter at the top and smaller at the bottom (20). The valve plate partition (16) has the same height as the valve plate. These will reduce the friction loss of the refrigerant in the cylinder, which will result in an improvement of the refrigerant flow rate, more suction pressure, and the higher coefficient discharge.
La modification des trous d'aspiration de la plaque porte-soupape selon l'invention a pour but d'augmenter le débit de réfrigérant du compresseur. Les trous d'aspiration modifiés (11 et 12) sont spécialement conçus pour présenter une forme fuselée dont le diamètre est supérieur au niveau de la partie supérieure et inférieur au niveau de la partie inférieure (20). La cloison de la plaque porte-soupape (16) présente la même hauteur que la plaque porte-soupape. Cela va permettre de réduire la perte de charge de frottement du réfrigérant dans le cylindre, ce qui résulte en une amélioration du débit de réfrigérant, une augmentation de la pression d'aspiration et une augmentation du coefficient de débit.
