Abstract

Dispositivo, en especial bomba, para la transformación de un movimiento de giro en un mismo sentido en un movimiento oscilante de vaivén, con: ¿ un disco (17), que puede girar alrededor de un eje central (20); ¿ un perno oscilante (18), que está apoyado en el disco (17) en forma giratoria alrededor de un eje (21) situado formando un ángulo respecto al plano del disco; ¿ un perno basculable (22), que está sujeto en el perno oscilante (18) formando un ángulo respecto al eje (21) del perno oscilante (18); y con ¿ un medio de sujeción (23), que impide que el perno basculable (22) realice un movimiento de giro alrededor del eje (20) del disco (17).
