Abstract
Abstract In a single-control mixing cock the proportion of mixing between hot water and cold water and the delivery flow rate are controlled by plates (10,14) of hard material sliding one with respect to the other along plane surfaces and contained within a replaceable cartridge supported in oriented fashion within the body of the cock. In order to avoid the necessity of replacing the articulated joints for the control lever of the cock, plates (10,14), control means (17), guide and motion-limiting means (23), are contained in the shell (5,6) of the cartridge, said control means (17) being provided with a coupling means (22) complementary and reciprocally engageable with coupling means (33) of the control lever (31) connected by the articulated joint (29) to a cap which retains the cartridge within the body of the cock.
