Valve controlled cartridge operated by a pushbutton for the mixing of water and/or for directing water coming from an inlet to one or more outlets

A cartridge for mixing and/or directing water, comprising:

• a piston valve (10) closing and opening fluid flow between at least one inlet and at least one outlet, in which a control valve (30) is arranged within the piston valve and operated by a double position mechanism by which the control valve (30) can be set into open and closed positions by the subsequent pressings of a pushbutton (27),
• wherein the control valve (30), the valve and the double position mechanism constitute a common mechanical unit all having a common axis (15), and the double position mechanism, the control valve (30) and the valve are arranged along the common axis (15) after one another in a housing (13), and the housing (13) is surrounded in a sealed way by a case (41) in which the housing (13) can be turned around the axis (15) within a predetermined angular range, and in the interior of the case (41) under the lower end of the housing (13) a ceramic stationary disc (42, 69, 75, 84) is arranged, and directly above the ceramic stationary disc (42, 69, 75, 84) with a common contacting plane a ceramic moving disc (43, 70, 76, 85) is arranged which can be turned together with the housing (13), and said at least one inlet and said at least one outlet are both arranged at a bottom of the case (41) and leading to the ceramic stationary disc (42, 69, 75, 84),
• wherein said piston valve is flow controlled and has a valve piston (17) guided in an interior of the housing (13) for axial displacement, and a bottom of the piston valve (10) comprises a valve seat (14) belonging to the housing (13),
• wherein the control valve (30) and the valve piston (17) are not directly mechanically connected,
• wherein said at least one inlet is lead through an inlet opening of the ceramic stationary disc (42, 69, 75, 84) and the ceramic moving disc (43, 70, 76, 85) and through a vertical lateral passage (16) completely provided in the interior of the housing (13) to an intermediate space (34) arranged in a closed state of the valve piston (17) between a top of the valve piston (17) and a bottom of the control valve (30), and
• wherein an interior space (12) of the housing (13) located under the valve seat (14) of the valve piston (17) is separated from said lateral passage (16) and constitutes an outlet space (49) communicating through said ceramic moving disc and said ceramic stationary disc to said at least one outlet, and the outlet space (49) is connected through a further passage (31) with an upper space (32) defined directly between the control valve (30) and said double position mechanism, and both said inlet opening and an outlet opening provided in the ceramic stationary disc and the ceramic moving disc (42, 69, 75, 84) and (43, 70, 76, 85) are arranged offset around the common axis, such that they are not coaxial with the common axis (15).
