Abstract
Un piston acumulador mejorado para una transmision automática. El piston consta de dos componentes, los primero y segundo siendo elementos de copasoldados entre sí por sus extremos cerrados en relacion colidante a tope. La copa inferior comprendeuna parte posterior curvada sobre sí misma, con una bridaradial que tiene sobre sí una junta bidireccional para aceite, que se extiende en sentido axial; y rebajos, separados entre ellos, en la parte posteriorcurvada sobre sí, para permitir que elaceit e fluya por ahí. La copa superior comprende una brida radial de diámetro reducido, en comparacion con una brida decopa inferior. La brida también tiene sobre ella una junta de labio. El piston está movido por un muelle, y asciende y desciendeen un p ar de ánimas opuestas,en respuesta al flujo de fluido sobre cada lado, para absorber los choques de desplazamiento.
