Abstract

UN MOTOR HIDRAULICO DE IMPACTO EN FORMA DE UNA MAQUINA PERFORADORA DE AGUJEROS EN UNA ROCA ACCIONADO POR AGUA TIENE UN RODETE DE VALVULA (40) QUE TIENE DOS SUPERFICIES DE CONTROL DIRIGIDAS IGUAL DE GRANDES Y OPUESTAS (A1 Y A2). LA VALVULA TIENE TAMBIEN UNA TERCERA SUPERFICIE DE CONTROL (A3) QUE ES MAS PEQUEÑA QUE LAS OTRAS DOS Y QUE ESTA CONTINUAMENTE BAJO PRESION. LA TERCERA SUPERFICIE DE CONTROL (A3) ACTUA EN LA MISMA DIRECCION QUE LA SEGUNDA SUPERFICIE DE CONTROL (A2). CUANDO LA PRIMERA SUPERFICIE DE CONTROL (A1) ESTA BAJO PRESION PERO LA SEGUNDA SUPERFICIE DE CONTROL (A2) NO LO ESTA, ENTONCES LA VALVULA SE MUEVE EN UNA DIRECCION, Y CUANDO LA PRIMERA Y SEGUNDA SUPERFICIES DE CONTROL (A1 Y A2) ESTAN BAJO UNA PRESION IGUAL (PRESION COMPLETA O SIN PRESION), ENTONCES LA VALVULA SE MUEVE EN LA OTRA DIRECCION MEDIANTE LA TERCERA SUPERFICIE DE CONTROL (A3).
