ABSTRACT:
The housing of a distributor valve has a first inlet for admission of a liquid which is maintained at a first pressure, a second inlet for admission of a liquid which is maintained at a higher second pressure, and at least two outlets. The cylindrical valving element has a first passage, one end of which is in permanent communication with the first inlet and the other end of which can be moved into register with a selected outlet in response to rotation of the valving element. The latter has a second passage, one end of which is in permanent communication with the second inlet and the other end of which registers with an outlet other than that which is in register with the other end of the first passage. The second passage and/or the second inlet admits highly pressurized flusing liquid into the clearances between the housing and the valving element to prevent penetration of liquid which is admitted via first inlet. The liquid which flows through the first passage contains solid particles, such as fragments of ore. The first passage resembles an elbow and extends along an arc of less than 46 degrees. The cross-sectional area of the first passage is constant and matches that of the first inlet as well as that of each outlet.
