PURPOSE:To omit the replenishing labor of a detergent, in a jet washing apparatus adapted to the supercharger of an exhaust gas turbine, by connecting a detergent discharge orifice to detergent supply piping and providing a control valve controlling the supply amounts of compressed air and the detergent to a connection port. CONSTITUTION:Detergent supply piping is connected to the detergent discharge port 28 of a detergent storage tank 27 storing a detergent and a ball valve 30 being a control valve controlling the supply of compressed air and the detergent, the stop of the supply of both of them and the supply amounts of both of them is provided to the connection part of said piping 29. The ball valve 30 has a ball 39 rotating by 360 deg. around its axis in the direction shown by an arrow and having a bore 40 constituting a flow path provided thereto. In such a state that the bore 40 of the ball 39 is in a vertical direction, the detergent 26 enters the bore 40 and, in a jet non-washing state, a jet washing state is obtained in such a state that the ball 39 is rotated by a predetermined angle. This cycle is performed by the half rotation of the ball 39. The ball valve 30 is rotationally driven on the basis of the detection value of the number of rotations of a main shaft by a control circuit but the amount of the detergent injected at once corresponds to the amount in the bore 40 of the ball 39. |
