Abstract
Prensa hidráulica que comprende: - una placa inferior (1) y una placa superior (2) adaptada para ser accionada con un movimiento vertical hacia dicha placa inferior mediante unos medios de control de movimiento y posición adecuados (3, 4, 5, 6), - un cilindro hueco (7) situado debajo de dicha placa inferior y dispuesto con su eje extendiéndose verticalmente, teniendo dicho cilindro su borde superior (8) aplicado con un ajuste sin huelgo contra la superficie inferior (9) de dicha placa inferior (1), - una columna de guía (10) conectada a la parte superior de dicha placa superior y cuyo extremo inferior forma el vástago de un pistón (13) adaptado para desplazarse dentro de dicho cilindro hueco, - un agujero (14) que se extiende a través de dicha placa inferior (1) y que está adaptado para acomodar dicha columna de guía que se desplaza verticalmente, - una abertura (15) provista en la superficie lateral de dicho cilindro hueco (7) y adaptada para permitir que dicho volumen interior (16), situado por encima de dicho pistón, se comunique con el medio hidráulico (17) adaptado para aplicar presión hidráulica dentro de dicho volumen interior cuando dicho pistón está en su posición inferior, caracterizada porque - dicha columna de guía está provista de una cavidad cilíndrica interna (18) que tiene un eje vertical y está llena de líquido hidráulico, extendiéndose dicha cavidad cilíndrica hasta el interior de dicho pistón (13) y saliendo del mismo por el extremo inferior de este, - se proporciona un pistón de tipo émbolo dentro de dicha cavidad cilíndrica interna, estando dicho pistón de tipo émbolo provisto de una parte cilíndrica superior (20) que tiene un diámetro tal que puede taponar dicha cavidad interna, y de una parte inferior (21) que tiene un diámetro menor para impedir que entre en contacto con las paredes de dicha cavidad cilíndrica interna (18), - se proporciona un agujero pasante (22) adaptado para permitir que dicha cavidad cilíndrica interna (18) se comunique con dicho volumen interior (16) cuando dicha parte cilíndrica superior (20) de dicho pistón de tipo émbolo está situada debajo del nivel de dicho agujero pasante.
