Abstract

Dispositivo de mando para la regulación de la velocidad de émbolos de trabajo neumáticos y/o hidráulicos y de los elementos de máquina accionados con ellos, en el que, al menos en una parte de la carrera del movimiento del elemento de máquina, se produce una modificación de la velocidad del émbolo de trabajo por medio de la presión dinámica en un líquido que circula paralelamente al movimiento de trabajo, siendo provocada está presión dinámica por orificios de estrangulamiento ajustados de forma fija o modificables en función de la posición del émbolo de trabajo, caracterizado por el hecho de que la primera corriente de líquido, que es arrastrada paralelamente por el émbolo de trabajo y/o por los elementos de máquina unidos al émbolo de trabajo.
