    摘要： A mobile apparatus (10) with a fluid pressure-operated implement (26) mounted at a distal end of a boom (20) includes a connection apparatus (42) for selectively rotating the implement (26) about an actuator axis at the distal end (24) of the boom (20). The connection apparatus (42) includes a rotary actuator (60) and a pressurized fluid circuit for delivery of pressurized fluid through the rotary actuator to the implement. The pressurized fluid circuit includes channels establishing a fluidic connection axially through the rotating shaft of the rotary actuator (60). The pressurized fluid circuit facilitates passage of pressurized fluid through an internal, protected environment to the implement (26).

    摘要： Fluidic actuator for a valve (50) or similar device, comprising:
    a housing (2) provided with a side wall (2a), a lower wall (2b) and an upper wall (2c);
    - a piston movable within said housing (2) and provided with a head (3a) and a rod (3b);
    - elastic return means (7) of the piston, which are functionally interposed between said head (3a) of said piston and a wall of said housing (2);
    - a plate (8) constrained to said piston so that to translate integrally to said piston, and arranged in the proximity of said side wall (2a) of said housing (2);
    - an indicator (9) of the position of the piston comprising a rotatable body rotatably constrained to said side wall (2a) of said housing (2) around a rotation axis and provided with a signaling portion at least visible outside of said housing (2) and with a protrusion (9a) of said rotatable body, the protrusion (9a) being arranged in an eccentric manner with respect to the rotation axis of the same rotatable body and arranged inside said housing (2);

    wherein said plate (8) comprises a cam profile and wherein said protrusion (9a) couples to said cam profile in order to make a cam-follower coupling such that the movement of the piston and the plate (8) in said housing (2) results in the at least rotating movement of said protrusion (9a) and, therefore, in the rotation of said rotatable body of said position indicator (9).
