Abstract

The telescopic actuator for a bucket loader in which a sliding motion is also combined with a rotary movement, has a main cylindrical housing fitted with end caps and inside which travels a piston (4) inside which fits a lower spindle portion, and integral with the piston is an upper spindle portion (5) passing through the upper end cap (2) and carrying a cup member at the top with distributor channels (18, 19) through it. Inside the upper spindle is an inner control rod (32b) with its head (33b) interacting with the distributor channels and its bottom (30b) which is splined, interacting with a further distributor space between the inside of the piston (4) and the end of the lower spindle portion, so that the splined member can be lifted, assisted by a spring (31b) and engage a grooved portion at the piston bottom.
