Title:
FOUR-WAY VALVE
Document Type and Number:
Japanese Patent JPS6037470
Kind Code:
A
Abstract:
PURPOSE:To have every two systems put in communication simultaneously and provide shutting-off altogether by forming two switching passages in parallel with a diametric line between in the valve body installed rotatably at the line intersecting part of four systems. CONSTITUTION:When lines 11a, 11b are to be put in communication as well as lines 11c, 11d in communication, a lever 23 is controlled so that switching passages 20a, 20b in the valve body 2 mate with their corresponding lines. When each line shall be shut in this mode, this lever 23 is controlled so as to provide dislocation of the valve body 2 for an angle of 45 deg.. At this time the lines 11a, 11b are blocked by the shutting surfaces 21a, 21b, respectively. If the valve body is rotated further 45 deg., the lines 11d, 11a are put in communication as well as the lines 11b, 11c in communication.
