HYDRODYNAMIC ROTATING POWER UNIT

The device enables rotation of the output shaft of the servo-drive into three positions without the use of additional mechanisms, while achieving simplicity, high driving torques and also relatively small size, weight and decreased acquisition costs. The first piston (4) is inserted by its bottom in...

Beschreibung
Zusammenfassung:	The device enables rotation of the output shaft of the servo-drive into three positions without the use of additional mechanisms, while achieving simplicity, high driving torques and also relatively small size, weight and decreased acquisition costs. The first piston (4) is inserted by its bottom into the cavity of the second piston (5), which is equipped with the inlet groove (19) of the pressure medium on its outer surface. The opening (20) adjoins the inlet groove (19) and opens into the inner space (21), which is created between the outer surface of the bottom of the first piston (4) and the inner surface of the bottom of the second piston (5), while the second piston (5) consists of sealing elements (6) along both sides of the groove (19).
