Abstract: A spray gun having a gun body is provided. A duct extends in the gun body between an inlet mouth and a main outlet mouth. The gun body has a handle, the inlet mouth located in the handle, extending along a handle axis; a barrel, the main outlet mouth formed in the barrel, extending along a barrel axis; and an adjustment element extending onto the barrel around and parallel to the barrel axis. The adjustment element has a central cavity accommodating the barrel and a secondary outlet mouth. The adjustment element is axially movable between a retracted position and a forward position, in which the adjustment element is advanced axially cantilevered on the barrel, with the secondary outlet mouth axially distal to the main outlet mouth, defining, within the central cavity, an adjustment chamber filled with water exiting the main outlet mouth to flow through the secondary outlet mouth.

Abstract: A device (1) for the assisted execution of a physical exercise by a user includes a sitting area (2) in which the user is accommodated. Leg movement devices (3) are suitable for accommodating the right and left foot, respectively, of the user to move them according to a rotatory trajectory with respect to a leg rotation axis (G-G). Arm movement devices (4) are graspable by the user with the right and left hand, respectively, to move them according to a rotatory trajectory with respect to an arm rotation axis (B-B) that extends parallel to the leg rotation axis (G-G). The device further includes an exercise controller (5) operatively connected to the leg movement devices (3) and to the arm movement devices (4) to transmit the respective movement simultaneously.
