FIELD: pipe-line fittings. SUBSTANCE: invention deals with mixing equipment designed to mix hot and cold water in various proportions. Mixer has hollow body with inlet branch pipes for hot and cold water. Linking member of valve head is installed in body of mixer uniaxially with each inlet branch pipe. Mixing chamber is formed in body of mixer between inlet branch pipes. This chamber communicates through valve distributor with outlet branch pipes for connection of shower or brush and discharge. Mentioned valve distributor includes two shut-off elements with seals and lever located in recess made in body of mixer. This lever is movably coupled to tail parts of shut-off elements. The latter are mounted in proper duct arranged vertically in body of mixer for longitudinal movement and shutting off of seat of outlet hole. Above-mentioned lever is rolling lever contacting bottom of mentioned recess. The latter is overlapped by separable cover. Separable cover has holes. Tail parts of shut-off elements are passed through these holes. Ends of tail parts of shut-off elements protruding outwards function as pressing elements for shifting over of valve distributor. Seats mentioned above are made in separable outlet branch pipes installed in outlet holes. EFFECT: increased functional reliability of mixer, simplified design of flow shifting device, decreased manufacturing cost of mixer. 2 cl, 5 dwg
