ABSTRACT:
A rotary slide valve is proposed, in which a cylindrical rotary plug is arranged in a cylindrical bore of a housing. A round passage bore in the rotary plug allows, on the one hand, a connection without jolting in all conveying directions of the likewise aligned first and second connection lines and a connection of the first connection line to a third connection line with a branching off at an angle without a change in terms of area of the passage cross section. In order to achieve a congruent transition of the connection cross sections of the first connection line with the passage bore through the rotary plug even in the case of branching off at an angle, these two bore holes of equal dimensions meet inside the rotary plug on a planar elliptical cutting surface of a median line of the angle. In the case of straight passage through the switch, the passage bore connects the connection lines, an adapted bore hole transition being provided in the second connection line from the exit opening on a cylinder envelope surface of the rotary plug to the round pipe diameter (D) to achieve a passage without jolting in both conveying directions in the second connection line.
