Abstract

CILINDRO PRINCIPAL TANDEM EN EL QUE EL PISTON SECUNDARIO (4) PRESENTA UNA CARA (40) SOBRE LA CUAL SE DESLIZA UN ANILLO (10) INTERPUESTO ENTRE UN PRIMER MUELLE (8) Y UNA SEGUNDA JUNTA (4B), REPELIENDO EL ANILLO LA SEGUNDA JUNTA (4B) CONTRA UN SALIENTE (41) DEL PISTON SECUNDARIO (4) PARA TRANSMITIR A LA SEGUNDA JUNTA (4B) UNA FUERZA DE COMPRESION QUE VARIA CON LA FUERZA EJERCIDA Y TRANSMITIDA POR EL MUELLE (8). SEGUN LA INVENCION, EL PISTON SECUNDARIO (4) PRESENTA UN TOPE (42) QUE LIMITA EL DESLIZAMIENTO DEL ANILLO (10) EN DIRECCION A LA SEGUNDA JUNTA (4B) EN EL ANIMA (1A) DEL CILINDRO PRINCIPAL, Y UNA REDUCCION PRACTICAMENTE TOTAL DE CUALQUIER DIFERENCIA DE PRESION ENTRE LOS CIRCUITOS PRIMARIO Y SECUNDARIO DEL CILINDRO PRINCIPAL.
