Abstract
PURPOSE: To manufacture a rotary valve for fluid control without any complicated control circuit nor mechanism, by using a cylinder and a plug having a turnk fitted loose in the cylinder.
CONSTITUTION: This valve is composed of a cylinder 2 and a plug 19 to be inserted loose to the inner surface 2A of the cylinder. The cylinder 2 has ports 4W9 and 10W 15 on the upper and lower portions, as a pair in positions dividing the external circumference of the cylinder 2 by 60 deg each. The plug 19 is composed of a flange 20 and a trunk 19A with reduced diameter below the flange 20. Grooves 21, 23 and 22, 24 are made on the external surface of the trunk 19A. Grooves 25W28 for fitting O-rings are also made to encircle the said grooves and O-rings 29W32 are fitted in the grooves respectively. The plug 19 has ports 33, 34 to be communicated with ports 15, 10, 11 and 6, 7, 8, 9 respectively and also has a port 35 for venting fluid.
