Abstract

476,379. Fluid - actuated valves. WINDSOR, G. P. July 21, 1936, No. 20264/37. Divided out of 478,516, [Group II] [Class 135] A valve for controlling the exhaust from, and the admission to, the air or gas chambers of a jigging apparatus for the treatment of coal or like materials, in which an alternating flow of water through a filtering screen is produced by regulating the flow of air or gas into a chamber, to the lower part of which the water has access, comprises a stationary cylindrical body 11 with internal passages 19, 20 for connection to a compressed-air or gas supply and to the chambers of the jigging apparatus respectively. A further passage 21 is provided for a controlling fluid which is delivered to the interior of a cap-like obturating member 15 for shifting it upon the body 11 to control the opening of the passage 20 to atmosphere through ports 16, 17 in the member 15 and corresponding ports 13, 14 in the body 11, and the communication between the air or gas inlet passage 19 to the passage 20 through an annular communicating channel 18 in the member 15 and ports 12 in the body. In a modified arrangement, a further exhaust passage is provided in the body 11 instead of exhausting direct to atmosphere, which passage is also controlled by the annular channel 18 in the obturating member 15.
