Abstract
LA INVENCION SE REFIERE A UNA CULATA, EN DONDE LA ZONA (5) PROXIMA A LA DESEMBOCADURA DE UNO O MULTIPLES CANALES (3) DE CAMBIO DE GASES ESTA FORMADA MEDIANTE UNA APLICACION (6'''') QUE SE EXTIENDE DE MODO COAXIAL CON RESPECTO A LA VALVULA (7) DE CAMBIO DE GAS. CON ELLO LA ZONA (5) PROXIMA A LA DESEMBOCADURA DEL CANAL (3) PUEDE SER ELABORADA DE FORMA MUY EXACTA Y SIN EMBARGO DE COSTE MUY ADECUADO, POR EJEMPLO MEDIANTE SINTERIZADO DE LA APLICACION (6''''). LA APLICACION (6'''') FORMA TAMBIEN LA GUIA (12'') DE VALVULA. SOBRE LA APLICACION (6) SE APOYA EL RESORTE (20) DE VALVULA. CON ELLO ES POSIBLE EL MONTAJE PREVIO DE UN MODULO DE VALVULA FUERA DE LA CULATA, QUE ABARCA LA VALVULA (7) DE CAMBIO DE GAS, EL RESORTE (20) DE VALVULA, EL PLATO (21) DE RESORTE, LA CUÑA (22) DE PLATO DE RESORTE, LA ESTANQUEIDAD DE VASTAGO DE VALVULA Y EVENTUALMENTE EL ANILLO (17) DE ASIENTO DE VALVULA. CON ELLO SE CONSIGUEN JUNTO A UNA GEOMETRIA DE CANAL EXACTA CON VENTAJA ADICIONAL UNA REDUCCION DE COSTES EN EL MONTAJE DELA CULATA DE CILINDRO.THE INVENTION REFERS TO A STOCK, WHERE THE AREA (5) NEXT TO THE OUTLET OF ONE OR MULTIPLE GAS CHANGE CHANNELS (3) IS FORMED BY AN APPLICATION (6 '' '') THAT EXTENDS IN A COAXIAL WAY REGARDING THE GAS CHANGE VALVE (7). THEREFORE, THE AREA (5) NEXT TO THE OUTLET OF THE CHANNEL (3) CAN BE PREPARED VERY ACCURATELY AND WITHOUT ANY APPROPRIATE COST, FOR EXAMPLE BY SINTERING THE APPLICATION (6`` ''). THE APPLICATION (6`` '') ALSO FORMS THE VALVE GUIDE (12``). ON THE APPLICATION (6) THE SPRING (20) OF THE VALVE IS SUPPORTED. WITH THIS IT IS POSSIBLE THE PRE-ASSEMBLY OF A VALVE MODULE OUTSIDE THE STOCK, WHICH COVERS THE GAS CHANGING VALVE (7), THE SPRING (20) OF THE VALVE, THE SPRING PLATE (21), THE WEDGE (22) OF SPRING PLATE, VALVE STEM SEALING AND EVENTUALLY VALVE SEAT RING (17). THEREFORE, THEY GET TOGETHER WITH AN EXACT CHANNEL GEOMETRY WITH ADDITIONAL ADVANTAGE, A COST REDUCTION IN THE MOUNTING OF THE CYLINDER HEAD.
