Abstract
A sequential mixing cartridge (,), for use with a cold and hot water mixing device, comprises with entry openings (,) for cold water and hot water and with a delivery opening (,) for mixed water. The interior of the body houses a sequential mixing slide valve (,) as well as operating members (,) for this mechanism partially protruding from the body. The shape and outside dimensions of the body as well as the arrangement of the inlet openings for cold water and hot water and for delivery of mixed water substantially match the construction and dimensions of a thermostatic mixing cartridge, thus achieving complete interchangeability with it. The sequential mixing mechanism (,) is preferably constructed to provide a delivery shut-off control member extension (,) for regulating the flow rate. Preferably, the body has inlet openings (,) for cold water and hot water on its outer surface and the delivery opening (,) for mixed water at its axial end that is axially opposite to the control member (,).
