Abstract
ELEMENTO HIDRAULICO PARA LA COMPENSACION DE LA HOLGURA DE UN MECANISMO DE VALVULAS DE UNA MAQUINA DE COMBUSTION INTERNA, QUE COMPRENDE UN EMPUJADOR INTERIOR (1) Y UN EMPUJADOR EXTERIOR (2) QUE ESTAN DISPUESTOS MOVILES RELATIVAMENTE ENTRE SI EN DIRECCION AXIAL, EN DONDE EL EMPUJADOR EXTERIOR (2) ESTA FORMADO POR UNA CAJA ESENCIALMENTE EN FORMA DE CAZOLETA CON UN FONDO PLANO, Y EN DONDE EL EMPUJADOR INTERIOR (1) Y EL EMPUJADOR EXTERIOR (2) LIMITAN UNA ZONA DE ACUMULACION (3) LLENA DE ACEITE, HERMETICA HACIA EL EXTERIOR, DE VOLUMEN VARIABLE, EN LA QUE HAY INCLUIDO UN ELEMENTO DE DESPLAZAMIENTO (4) PARA COMPENSAR LAS VARIACIONES DE VOLUMEN. EL EMPUJADOR EXTERIOR (2) ESTA FORMADO POR UNA ENVOLTURA (7) DE MATERIAL SINTETICO TERMOPLASTICO ESENCIALMENTE FORMA TUBULAR Y QUE PRESENTA, AL MENOS EN ZONAS PARCIALES, SUPERFICIES DESLIZANTES RADIALES INTERIORES Y EXTERIORES (5, 6), QUE ESTA CERRADO EN DIRECCION A UN ARBOL DE LEVAS (8) APLICABLE MEDIANTE UN DISCO ESTANCO AL LIQUIDO (9) EJECUTADO COMO CONTRARROTOR. LA SUPERFICIE DESLIZANTE INTERIOR RODEA EL EMPUJADOR INTERIOR (1) EN TODO SU PERIMETRO Y ESTANCO AL LIQUIDO.
