Multiple valve core, multiple valve and valve arrangement

Abstract

A valve assembly comprises at least one multiple valve having a duct module which includes at least one elongated fluid duct which extends in a straight line along a longitudinal direction and a plurality of branch ducts which open in openings in the fluid duct which are arranged side by side along the longitudinal direction in the inner wall of the fluid duct. The multiple valve comprises at least one multiple valve core which is inserted into the fluid duct such that each valve seal can seal one of the openings. The multiple valve core comprises an elongated carrier and at least one valve element, the carrier having at least one support portion for abutment against the inner wall of the fluid duct and at least one receiving area in which the valve element is connected to the carrier so as to be non-displaceable in the longitudinal direction of the carrier. A plurality of valve seals for closing the openings which are provided on one or on a plurality of valve elements is provided, the valve seals being arranged successively in the longitudinal direction of the carrier and being movable in a closing direction perpendicular to the longitudinal direction. The duct module forms part of a basic module on which a plurality of valve modules fluidically connected to the branch ducts can be mounted, the valve modules being in particular configured so as to be adapted to actuate pressure pieces in the branch ducts which cooperate with the valve seals of the valves of the multiple valve to permanently open the respective valve.
