Abstract

Generador solar (G), con un reflector (Y), en particular un colector solar cilindrico parabólico (3) con tubo absorbente (4), y un dispositivo de seguimiento de la altura del sol electrohidráulico para el reflector, que presenta al menos un cilindro hidráulico (5), en el quo entre al menos una linea de trabajo (11, 12, 13, 14) del cilindro hidraulico y una fuente de presión (19, 20) está prevista una valvula de asiento de regulación (V), caracterizado porque el reflector (Y) puede seguir continuamente y sin interrupciones de forma sincrona al curso del sol a traves de la válvula de asiento de regulación (V), y porque la válvula de asiento de regulación (V) presenta en una zona de asiento una superficie de asiento (33) y una superficie obturadora (34), quo en una posición de regulación se sitúan una contra otra con un apriete variable sin elevación con retirada, y entre las quo se puede generar un flujo de medio de presión como fuga controlada a fin de suministrar un flujo de medio de presión a al menos un cilindro hidráulico, y porque al menos la superficie obturadora (34) esta hecha de un material deformable bajo el apriete.
