VALVE, VALVE ACTUATING DEVICE, CARTRIDGE AND ADAPTER FOR A LIQ-UID TREATMENT SYSTEM

Abstract

A liquid treatment cartridge has a housing, the housing including at least one liquid-permeable window (43a-d) forming a liquid inlet, at least one liquid-permeable window (42a,b) forming a liquid outlet, at least one treatment chamber, e.g. including a liquid treatment medium, situated between and in liquid communication with the liquid-permeable windows (42a-d, 43a,b) forming the liquid inlet(s) and outlet(s), and a device for actuating a valve for regulating a flow of liquid through a channel in a wall of a cartridge seat of a liquid treatment system. The valve includes at least a valve body (15) defining at least one port, and at least one movable valve component (16), movable with respect to the valve body (15). The at least one movable valve component (16) includes a regulating part for selectively obstructing a flow of liquid through the at least one port and an actuating part for engaging the valve actuating device when the valve actuating device is inserted into the cartridge seat. The actuating part includes a member of each of at least one pair of a spiral contour and a part (41a,b;63a,b) for engaging the spiral contour and is comprised in a mechanism for converting linear motion in axial direction of the valve actuating device into rotary motion of the at least one movable valve component (16) about the axis or a parallel axis. A section of the actuating device for engaging the actuating part is insertable in the axial direction through an opening for admitting liquid to the valve, which section is included in the mechanism and includes the other members of the at least one pair. The mechanism includes the parts for engaging a spiral contour and the spiral contours.
