Abstract

2.1. EL OBJETIVO DE LA INVENCION ES CONFIGURAR UN EQUIPO PARA CONTROL Y REGULACION DE LA PRESION DE TAL MODO, QUE SE REDUCE LA SOBREOSCILACION DE LA PRESION EN LA APLICACION DEL EMPUJADOR CON PROCEDIMIENTOS ROBUSTOS Y POR MEDIO DEL PERSONAL DE SERVICIO EVENTUALMENTE DE MANERA EXTRAIBLE COMPLETAMENTE DE FORMA POSTERIOR Y SE MINIMIZA ADICIONALMENTE LA VIA DE FORMACION DE PRESION DE LA ESTAMPA DE GOMA. 2.2. EL ACEITE QUE SE ENCUENTRA EN EL ESPACIO DE CILINDRO (11) DE LA ESTAMPA DE GOMA SE CORRESPONDE A TRAVES DE UNA CONDUCCION (28) CON EL TANQUE (13) QUE DISPONE DE PRESION PREVIA. EN LA CONDUCCION (28) SE DISPONE DE UNA VALVULA (12) PROPORCIONAL Y EN EL LADO DEL TANQUE SE IMPULSA CON UNA CONTRAPRESION DEFINIDA DE TAL MODO, QUE SE COMPENSAN LAS FUERZAS DE MASA, QUE ACTUAN SOBRE EL EMBOLO DEL CILINDRO (11) DE ESTAMPA DE GOMA Y DE FORMA QUE SE CONTROLA Y REGULA LA VALVULA (12) PROPORCIONAL CON EL REGULADOR (23) DE FUERZA DE ESTAMPA, ENCONTRANDOSE EN UNION ACTIVA Y SIENDO REGULADO Y CONTROLADO POREL.2.1. THE OBJECTIVE OF THE INVENTION IS TO CONFIGURE A PRESSURE CONTROL AND REGULATION EQUIPMENT IN SUCH A WAY, WHICH REDUCES OVERPRESSURE OF THE PRESSURE IN THE APPLICATION OF THE PUSHER WITH ROBUST PROCEDURES AND BY MEANS OF SERVICE PERSONALLY FULLY REMOVABLE. POSTERIOR AND THE PRESSURE FORMATION ROUTE OF THE RUBBER STAMP IS ADDITIONALLY MINIMIZED. 2.2. THE OIL THAT IS IN THE CYLINDER SPACE (11) OF THE RUBBER STAMP CORRESPONDS THROUGH A CONDUCTION (28) WITH THE TANK (13) THAT HAS PREVIOUS PRESSURE. IN THE CONDUCTION (28) A PROPORTIONAL VALVE (12) IS AVAILABLE AND ON THE SIDE OF THE TANK IT IS IMPELLED WITH A DEFINED COUNTERPRESSURE, SO THAT THE MASS FORCES, WHICH ACT ON THE CYLINDER PISTON (11) OF RUBBER STAMP AND IN A WAY THAT THE PROPORTIONAL VALVE (12) IS CONTROLLED AND REGULATED WITH THE STAMP FORCE REGULATOR (23), BEING IN ACTIVE UNION AND BEING REGULATED AND CONTROLLED BY IT.
