Abstract

pistão, e método para construir um pistão. um pistão tem um par de porções de saia diametricamente opostas com superfícies externas convexas. cada porção de saia tem bordas laterais opostas estendo-se substancialmente paralelas a um eixo central do pistão para uma extremidade livre. cada uma das porções de saia tem uma fenda de recesso estendendo-se radialmente na superfície externa convexa para uma superfície em recesso. a superfície em recesso estendendo-se totalmente através da superfície externa convexa para as bordas laterais e separa uma seção de banda superior da superfície externa convexa de uma seção de banda inferior da superfície externa convexa.
