PCT No. PCT/AU92/00652 Sec. 371 Date Jun. 6, 1994 Sec. 102(e) Date Jun. 6, 1994 PCT Filed Dec. 3, 1992 PCT Pub. No. WO93/10914 PCT Pub. Date Jun. 10, 1993.The specification discloses a cleaning apparatus (2) for cleaning machine and engine parts comprising a trough (4) in which the cleaning is performed. A lid (6) is connected to the trough (4) and is movable between a closed position covering the trough and an opened position allowing access to the trough. A first cleaning fluid dispenser in the form of a manifold (8) is located within the apparatus (2). Also provided is a portable cleaning fluid dispensing gun (10) or brush (12) which is connectable to the apparatus (2). The lid (6) operatively cooperates with the manifold (8), gun (10) or brush (12) so that when the lid (6) is in the closed position, cleaning fluid is dispensed through the manifold (8) and when the lid (6) is in the opened position, cleaning fluid can be dispensed through the gun (10) or brush (12). A pump (14) is provided for pumping the cleaning fluid to the manifold (8), gun (10) or brush (12). A supply of the cleaning fluid is held within the tank (8) formed integrally with the apparatus (2). A ball valve (32) housed within the pump (14) selectively directs cleaning fluid to the manifold (8) or with the gun (10) and brush (12). The ball valve (32) is provided with a control arm (34), the manipulation of which changes the state of the ball valve. The control arm (34) is pivotably connected to one end of a lever (36). An opposite end of the lever (36) is pivotably connected by pivot pin (37) to arms (38 and 39). An end of the arm (38) distant from lever (36) is pivotably connected to an outside wall of the trough (4) in the vicinity of the lid (6). An end of arm (39) is pivotably connected to the lid (6). By this arrangement of levers, the opening or closing of the lid (6) changes the state of the ball valve (32).
