FIELD: jet treatment of parts. SUBSTANCE: installation has a tub with drain pipeline, installed in it members to form jets for washing parts in perforated drum connected to the primary washing liquid supply system. Fastener for driven perforated drum is placed in tub. Means for effecting combined washing (jet and immersed) in perforated drum is made as a tray installed for rotation by aid of an actuating device. Installation is provided with members for forming jets to wash parts on suspension rods, the members being connected to additional washing liquid supply system. Installation is also provided with a bar to fasten parts on suspension rod. The tray is installed to reciprocate by agency of corresponding actuators and shafts with axles which are put into bearings and rigidly connected with working media of tray actuators. Some ends of rods are rigidly attached to side ends of tray and the rest connected with working media of actuators to rotate the tray. The latter and corresponding working media are made with recesses. As above-said tray reciprocation and rotation actuators, pneumatic cylinders are used. Their operation control is effected by three-way electromagnetic pneumatic valves. As pneumatic cylinders, piston-type bilateral action pneumatic cylinders are used provided with spring return into initial state. EFFECT: improved design. 3 cl, 2 dwg
