Washing apparatus

A washing apparatus, comprising:

• a washing chamber delimited by two lateral walls, a bottom wall and an upper wall, provided at the front with an inlet aperture for inlet and/or outlet;
• a main distribution circuit for a treatment fluid, configured to distribute the treatment fluid inside the washing chamber;
• at least a trolley-type movement device configured to be removably inserted into said washing chamber via said inlet aperture and comprising a frame configured to support objects to be subjected to a washing cycle in the washing chamber and on which distribution elements for the treatment fluid are mounted, said frame being formed by hollow tubular elements functioning as a secondary distribution circuit for the washing liquid to the distribution elements,
• at least a connector element located on the upper part of the frame and which functions as a delivery element for delivering treatment fluid to the secondary distribution circuit,
• a hydraulic connection pipe mounted on said upper wall, which is configured to hydraulically connect the main distribution circuit to the connector element of the secondary distribution circuit, said hydraulic connection pipe being vertically movable between a first position connected to the connector element and a second position separated from the connector element, and having a movable part and a fixed part with respect to said upper wall of said chamber;
• and
• a linear actuator configured to move the hydraulic connection pipe between the first position connected to the connector element and the second position separated from the connector element, wherein said connector element comprises a funnel and said movable part is provided with a pipe union configured to be inserted and coupled into the funnel for hydraulic connection, and wherein said linear actuator has a piston configured to move the hydraulic connection pipe, wherein said piston is axially offset from said movable part and is connected to said movable part by a joint element.
